Integrated system for distribution box design + quotation: A must-have tool for merchants, enabling them to go from drawings to quotations in just 10 minutes

AI intelligent recognition system diagram, automatic selection, visual layout design, and one-click generation of quotation sheets, making it an essential efficiency tool for merchants

Preface: I understand the pain points of merchants too well

I have been involved in industrial automation for 20 years and have run an electrical company, so I fully understand the difficulties faced by merchants in the distribution box industry.

Have you often encountered these situations?

Scenario 1: The customer sends a system diagram, but you can't understand it

The customer sends a WeChat message: "Mr. Wang, can this distribution box be made? Please provide a quotation."
You look at the drawing for a long time:

• What component is this? Schneider or ABB?
• What does this symbol represent?
• How is the layout inside the box? How many rows of guide rails should be placed?
• How many circuit breakers and contactors are needed?

Asking about technology, the technician said, "Let me research it and get back to you tomorrow."
Customer: "Too slow, I've found someone else."

Scenario 2: Slow design, prone to errors

The technician uses CAD to draw:

• Drawing components one by one, time-consuming
• Size calculation error, discovered during production
• Missing a component, requiring a drawing revision
• Customer says "make changes", and start all over again

Scenario 3: Inaccurate quotation, loss of money

Salesperson quotes based on experience:

• Missing 2 circuit breakers
• Box thickness is calculated too thin
• Insufficient estimation of copper bar usage
• End up with a loss of 15,000

Scenario 4: Customer wants to change the plan, but response is slow

Customer: "Can we replace Schneider with ABB?"
You: "I'll wait for the technical team to calculate."
Customer: "Then I'll ask other companies first."

The most troublesome thing is:

• that every project requires redesign, resulting in repetitive work
• Newcomers can't design, leading to high training costs
• Design and quotation are separated, resulting in low efficiency
• Customers are in a hurry, and we can't afford to wait

I know all these pain points.

Therefore, I have developed thisintegrated system for distribution box design and quotation.

. It is not meant to replace manual labor, but rather tohelp merchants reduce costs and increase efficiency.

. First, core functions: why do merchants say it's good?

1.1 AI intelligent recognition: upload photos, automatically identify components

Function description:

The system automatically identifies when customers send system diagrams (photos/PDFs/CADs):

① Intelligent component recognition

• Circuit breakers, contactors, relays, PLCs, instruments...
• Automatically identify brands (Schneider/ABB/Siemens/Chint...)
• Automatically identify models, specifications, and quantities

② Confidence Score

• Each recognition result has a confidence level (such as 95%)
• For components with low confidence, manual review is required
• For those with high confidence, they can be directly adopted

③ Material Matching

• Matched: The system has found the corresponding model
• To be confirmed: Requires manual confirmation
• Unmatched: Not found in the library, manual addition is required

④ Intelligent Completion

• Automatic reminder for missing items
• "3 circuits detected, but only 2 circuit breakers selected, do you want to complete?"
• Avoid missing or incorrect items

Usage Scenario:

客户发来一张配电箱系统图照片

II. Merchant Cases: Real Effects

Case 1: A distribution box factory in Zhejiang

Background:

• Main products: PZ30, XL-21, GGD distribution boxes
• Team: 5 salespersons + 3 technicians + 10 workers
• Pain points: Slow design, slow quotation, many errors and omissions

After using the system:

The boss said:

, "In the past, we had to work overtime every day on drawing and quotation, but it was still slow. Now, salespeople can design and quote on their own, propose solutions on the spot, and sign deals on the spot. We've done an additional 2.7 million yuan of business in one month, which is so worth it!"

Case 2: An electrical company in Jiangsu

Background:

• Main business: GGD, GCK, MNS distribution cabinets
• Team: 3 salespeople + 2 technicians
• Pain points: Newcomers can't design, and the training cost is high

After using the system:

• Newcomer training period: 3 months → 1 week
• Design standardization: Consistent designs across different salespeople
• Reduced turnover risk: No longer reliant on personal experience

Sales manager said:

"In the past, when recruiting a new person, we needed experienced salespeople to train them for 3 months. Now, after just 1 week of training, they can use the system and design and quote more accurately than the experienced salespeople. Plus, there's no need to worry about the experienced salespeople leaving, because all the experience is stored in the system."

Case 3: A Power Equipment Company in Guangdong

Background:

• Main Business: Box-type Substations, Ring Main Units
• Team: 10 Salespeople + 5 Technicians
• Pain Points: Complex Projects, Long Design Cycles

After Using the System:

• Solution Generation Time: 5 Days → 10 Minutes
• Customer Satisfaction: 60% → 95%
• Repurchase Rate: 25% → 65%

General Manager Says:

"When we do box-type substation projects, each project can cost hundreds of thousands or even millions. In the past, it took 5 days to design. Now, the system can generate a solution in 10 minutes, and the customer can confirm it on the spot. The repurchase rate has also increased because the solution is professional and the price is transparent.

VI. Applicable Objects

Suitable for the following merchants to use:

✅ Distribution box manufacturers (PZ30, XL-21, GGD, GCK, etc.)
✅ Complete equipment factories (distribution cabinets, control cabinets)
✅ Electrical companies (agents of Schneider, ABB, Siemens)
✅ Power equipment companies (box transformers, ring main units)
✅ Automation companies (PLC control cabinets, frequency conversion cabinets)
✅ Engineering companies (electromechanical installation, power distribution engineering)

Not suitable:

❌ Pure retail (single-item sales, no need for a plan)
❌ Used equipment (non-standard models)
❌ Completely non-standard customization (no standard configuration)

VII. Lastly

I developed this system not to replace human labor.

Instead, it's to liberate human resources.

It allows salespeople to stop waiting for technology, technology to stop repetitive work, and bosses to stop worrying about quotation errors.

It allows everyone to spend their time on more valuable things:

• Sales: maintaining customer relationships
• Technology: solving complex problems
• Boss: Strategic Planning

Tools are not enemies, but helpers.

Merchants who make good use of tools will eliminate those who do not.

I hope this system can help more peers.
