Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual welding of wires is used to connect electrode to driver board, then electrical connection is achieved, but production process becomes complicated and inefficient

Engineering Contradiction:
Improveelectrical connectionVSAvoidproduction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual welding process with a mechanical insertion system. The insert terminal is simply inserted into the elastic clamping portion formed by the connection sheets, eliminating the need for welding equipment and manual welding operations. This mechanical substitution dramatically improves production efficiency while maintaining reliable electrical connection through the elastic clamping force.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual welding of wires is used, then electrical connection is achieved, but production process becomes complex

Engineering Contradiction:
Improveelectrical connectionVSAvoidproduction process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the wire threading and welding operations from the connection process. Instead of using separate wires that need to be manually threaded through electrode pins and welded to the driver board, the invention integrates the electrical connection function into a single insert terminal that connects directly to the elastic clamping portion, simplifying the overall production process.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The elastic clamping portion formed by the connection sheets acts as an intermediary between the insert terminal and the electrode connection board. This intermediary structure provides both mechanical support and electrical connection in one component, eliminating the need for separate wires and welding operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If wires are manually threaded and welded, then electrical connection is achieved, but automated production becomes difficult

Engineering Contradiction:
Improveelectrical connectionVSAvoidautomated production capability
Core Design Contradiction:
ReliabilityVSExtent of automation

Solution Approach 1:

The patent replaces the complex manual welding process with a simple mechanical insertion operation. The insert terminal is designed to be inserted into the elastic clamping portion, which automatically secures the connection through elastic force. This mechanical substitution enables automated production as the insertion process can be easily automated without requiring welding equipment or skilled operators.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If wires are used for connection, then electrical connection is achieved, but positioning and arrangement becomes difficult

Engineering Contradiction:
Improveelectrical connectionVSAvoidpositioning and arrangement
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent removes the wires from the connection system and replaces them with a rigid insert terminal that has fixed positioning features. The insert terminal is designed with specific dimensions and insertion direction, making positioning and arrangement straightforward during assembly, unlike flexible wires that require manual threading and positioning.

Inventive Principle:
Principle #2Taking out (Extraction)
