The connection between the wire and the printed circuit board in existing connector converters is prone to detachment due to small welding areas, leading to instability and poor performance.

Innovation Solution

A connector converter design featuring a metal plate embedded in the digital signal board, providing both electrical and mechanical connections via a connecting terminal, instead of welding, to enhance stability and prevent detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If spot welding is used to connect the wire to the printed circuit board, then the manufacturing process is simple, but the connection is prone to detachment and reliability is poor

Engineering Contradiction:
Improvewelding process simplicityVSAvoidconnection stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The wire connection structure is segmented into multiple components: the wire body, the metal plate, and the connecting terminal. This segmentation allows each component to perform its specific function optimally - the metal plate provides a large embedding area for mechanical stability, while the connecting terminal ensures reliable electrical connection to the circuit board, resolving the contradiction between simple manufacturing and reliable connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solution employs composite material structure by combining the metal plate (providing mechanical strength and embedding capability) with the connecting terminal (providing electrical conductivity and board mounting). This composite approach creates a connection system that simultaneously achieves both mechanical stability and electrical reliability, overcoming the limitations of single-material spot welding.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If spot welding is used to connect the wire to the printed circuit board, then the manufacturing process is simple, but the welding area is small and mechanical connection strength is insufficient

Engineering Contradiction:
Improvewelding process simplicityVSAvoidmechanical connection strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The connection approach transitions from two-dimensional spot welding (small area contact) to three-dimensional embedding connection (large volume engagement). The metal plate is embedded within the wire cross-section, creating a multi-dimensional mechanical interlock that dramatically increases connection strength while maintaining manufacturing feasibility through standardized embedding processes.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The metal plate and connecting terminal are merged into an integrated assembly that combines mechanical embedding function with electrical connection function. This merging eliminates the need for separate welding operations while providing both strong mechanical attachment and reliable electrical conductivity, simultaneously addressing manufacturing simplicity and connection strength requirements.

Inventive Principle:
Principle #5Merging (Combining)
