Solution Overview

Problem

The complexity and number of assembly steps increase significantly when connecting multiple storage batteries in series, leading to complicated wiring and connection work.

Innovation Solution

A storage battery connection module with a base plate of integrated insulating plates, connection terminals, and power lines that connect terminals in series, along with a dedicated wire harness for each type of storage battery, simplifies the assembly process by pre-wiring power lines and terminals, reducing the need for extensive wiring and connection work.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large number of storage batteries are connected in series using conventional wiring methods, then the power storage system can achieve high capacity, but the number of assembly steps and wiring work increases significantly

Engineering Contradiction:
Improvenumber of storage batteriesVSAvoidnumber of assembly steps
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines multiple wiring functions into a single integrated base plate structure. The base plate integrates multiple connection terminals and power lines into one component, allowing multiple batteries to be connected simultaneously through a single assembly operation rather than requiring separate wiring steps for each connection.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base plate is pre-configured with connection terminals and power lines before assembly. The wiring layout is predetermined and fixed on the base plate, so that during assembly, workers only need to connect batteries to the pre-wired base plate without performing complex wiring operations on the assembly line.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple storage batteries are connected in series with individual wiring, then each battery can be independently connected, but the wiring connection work becomes complicated

Engineering Contradiction:
Improveindependent battery connectionVSAvoidwiring connection work
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The base plate serves multiple functions simultaneously: it provides mechanical support for multiple batteries, contains pre-configured power lines for electrical connections, and houses connection terminals for interfacing. This multi-functional design eliminates the need for separate wiring operations while maintaining the ability to connect multiple batteries independently.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If conventional wiring methods are used to connect storage batteries, then flexibility in connection configuration is maintained, but the number of power lines and signal lines increases

Engineering Contradiction:
Improveconnection configuration flexibilityVSAvoidnumber of power lines and signal lines
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The base plate creates a standardized connection template that can be replicated for multiple batteries. Instead of creating unique wiring paths for each battery connection, the same base plate design with integrated power lines and terminals is used repeatedly, reducing the overall number of individual wires needed while maintaining connection flexibility.

Inventive Principle:
Principle #26Copying
