Innovation Solution

A wiring device with a first terminal assembly and a second terminal assembly, featuring sliding structures, guiding structures, and a mounting structure that facilitate easy connection and disconnection of wiring terminals without affecting the wiring holes, along with a protective cover plate for stability and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wires are placed in the electronic control box in a conventional manner, then the air conditioner can operate, but the production efficiency of plugging and closing the cover is very low due to chaotic wire arrangement

Engineering Contradiction:
Improveproduction efficiencyVSAvoidwire management convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The wire management system is segmented into multiple wire storage slots and guide structures, dividing the chaotic space into organized sections. Each wire type has its designated storage location and routing path, transforming the undifferentiated wire mass into structured, manageable segments that can be efficiently assembled and disassembled.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If wires are arranged chaotically in the electronic control box, then installation is simple, but jamming and crimping phenomena occur easily, increasing quality hidden dangers

Engineering Contradiction:
Improveinstallation simplicityVSAvoidwire connection reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

Wire guide structures and storage slots act as intermediary elements between the wires and the final assembled position. These intermediaries provide controlled pathways that prevent direct contact and potential damage between wires, eliminating jamming and crimping while maintaining installation simplicity through the guiding function.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If wiring terminals are used to organize wires, then wire management improves, but both ends of the wiring terminals are difficult to cooperate with each other, increasing mounting difficulties

Engineering Contradiction:
Improvewire management convenienceVSAvoidmounting difficulty
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wiring terminals are pre-configured with matching connection structures during manufacturing. The male and female connectors are designed with complementary geometries and positioning features that ensure automatic alignment and easy engagement, eliminating the cooperation difficulties that would otherwise arise during assembly.

Inventive Principle:
Principle #10Preliminary action
