Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional coupling methods are used to connect stand base and stand neck, then connection strength is improved, but assembly and disassembly complexity increases

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The coupling hole and elastic block are integrated into the coupling portion structure, merging the fastening function and locking function into a single integrated component. This eliminates the need for separate coupling members while maintaining both connection strength and ease of assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elastic block automatically engages with the coupling hole through elastic deformation when the stand neck is inserted, and automatically locks without requiring external tools or additional coupling members. The structure serves itself by using the elastic property of the block to create automatic engagement and locking.

Inventive Principle:
Principle #25Self-service

2Reliability

If secure locking mechanism is implemented, then reliability of connection is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The elastic block automatically engages with the coupling hole through elastic deformation when the stand neck is inserted, and automatically locks without requiring external tools or additional coupling members. The structure serves itself by using the elastic property of the block to create automatic engagement and locking.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elastic block changes its physical state through elastic deformation, transitioning from a compressed state during insertion to an expanded state during locking. This parameter change enables the block to provide secure locking while maintaining ease of operation through simple insertion and removal motions.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If tool-free assembly is implemented, then ease of operation is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveassembly easeVSAvoidcoupling precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The elastic block changes its physical state through elastic deformation, transitioning from a compressed state during insertion to an expanded state during locking. This parameter change enables the block to provide secure locking while maintaining ease of operation through simple insertion and removal motions.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The coupling mechanism is divided into distinct functional elements: the coupling hole, the elastic block, and the coupling portion. This segmentation allows each component to be manufactured with standard tolerances while achieving precise engagement through the elastic deformation of the block, reducing overall manufacturing precision requirements.

Inventive Principle:
Principle #1Segmentation
