Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape is used to fix connectors, then the connectors are held together, but the adhesive force is insufficient and the adhesive easily remains on objects' surface

Engineering Contradiction:

Improveconnector connection reliabilityVSAvoidadhesive residue on surface

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the chemical bonding mechanism of adhesive tape with a mechanical fastening system consisting of a fixing piece with buckling sections that engage with buckling slots in the connectors. This mechanical interlocking provides reliable connection without leaving adhesive residues on surfaces.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The fixing piece utilizes elastic deformation of its buckling sections to achieve a snap-fit connection. The elastic material allows the buckling sections to deform during assembly and then maintain a fixed position, providing reliable mechanical fastening without the drawbacks of adhesive.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If silicone is used to fix connectors, then the connectors are held together, but it takes time to solidify the silicone

Engineering Contradiction:

Improveconnector connection reliabilityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the time-dependent chemical curing process of silicone with an immediate mechanical snap-fit system. The elastic buckling sections provide instant mechanical engagement upon assembly, eliminating the waiting time required for adhesive solidification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If iron wire or cable tie is used to fix connectors, then the connectors are held together, but the operation is difficult and assembly and disassembly efficiency is decreased

Engineering Contradiction:

Improveconnector connection reliabilityVSAvoidassembly and disassembly convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fixing piece is designed to be self-fastening through the snap-fit mechanism. The elastic buckling sections automatically engage with the buckling slots when the connectors are inserted, providing self-service fastening without requiring complex tying or wrapping operations.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The fixing piece incorporates elastic buckling sections that can dynamically deform during assembly and disassembly. This elasticity allows for easy insertion and removal of connectors while maintaining a secure fixed position during operation, improving both ease of operation and connection reliability.

Inventive Principle:

Principle #15Dynamics

4Ease of operation

If connectors are inserted and connected without a fixing piece, then assembly is simple, but the connectors are easily separated when pulled by external force

Engineering Contradiction:

Improveassembly simplicityVSAvoidconnector connection reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a mechanical fastening system with buckling sections and buckling slots that provides secure mechanical interlocking between connectors. This maintains the simplicity of connector insertion while adding reliable mechanical retention to prevent separation under external forces.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The elastic buckling sections provide dynamic mechanical retention that secures connectors during normal operation while allowing for controlled disassembly. The elastic deformation capability maintains connection reliability without overly complicating the assembly process.

Inventive Principle:

Principle #15Dynamics
