Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If gluing or fasteners are used to connect parts, then connection strength is improved, but manufacturing complexity increases and automation becomes difficult

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

Solution Approach 1:

The lamp holder is divided into multiple modular sections (first lamp holder section, second lamp holder section, end cap) that can be independently manufactured and then assembled through simple plug-in operations, reducing overall manufacturing complexity while maintaining connection strength

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection structure integrates the fixing hole, convex portion, and guide groove into a unified plug-in mechanism that combines alignment and fixation functions, eliminating the need for separate gluing or fastening operations

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If manual assembly is used, then connection precision is improved, but production efficiency decreases

Engineering Contradiction:
Improveconnection precisionVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The guide groove and convex portion are pre-formed during manufacturing, establishing precise alignment features before assembly. This preliminary preparation enables automated systems to achieve high precision connections without manual intervention

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The plug-in structure with guide groove and convex portion enables self-alignment and self-fixation during assembly. The components automatically find their correct positions and secure themselves, eliminating the need for manual positioning and adjustment

Inventive Principle:
Principle #25Self-service

3Extent of automation

If plug-in fitting is used for end cover and lamp holder, then automation is improved, but connection reliability may decrease

Engineering Contradiction:
Improveautomation capabilityVSAvoidconnection reliability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The connection structure uses a combination of metal lamp holder and plastic/nylon end cap materials. The material complementarity provides both the precision needed for automated plug-in assembly and the mechanical strength for reliable connections, with the harder metal providing structural integrity and the softer plastic providing friction-based locking

Inventive Principle:
Principle #40Composite materials
