Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate mechanical and electrical attachment procedures are used, then secure attachment is achieved, but installation time and complexity increase

Engineering Contradiction:
Improvesecure attachmentVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines mechanical attachment and electrical connection into a single integrated fastening device. The retaining bolt simultaneously provides mechanical retention and electrical contact through its conductive structure, eliminating the need for separate mechanical and electrical attachment procedures while maintaining secure attachment and reducing installation time

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If separate mechanical and electrical attachment procedures are used, then secure attachment is achieved, but installation complexity increases

Engineering Contradiction:
Improvesecure attachmentVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fastening device integrates mechanical retention components (retaining bolt, housing) and electrical connection components (contact elements, terminals) into a single unified structure. This merging reduces installation complexity by eliminating separate procedures while ensuring secure attachment through the coordinated action of integrated components

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If additional tools are required for assembly, then precise assembly is achieved, but assembly speed decreases

Engineering Contradiction:
Improveassembly precisionVSAvoidassembly speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The fastening device is designed to be self-assembling without requiring additional tools. The retaining bolt can be manually inserted and secured, and the electrical contacts automatically engage when the mechanical components are assembled. This self-service design maintains assembly precision through built-in alignment features while significantly increasing assembly speed

Inventive Principle:
Principle #25Self-service
