Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the vertical orientation of one lighting module is adjusted, then the orientation of that module is improved, but the light distribution of the overall beam is modified which may not meet statutory requirements

Engineering Contradiction:

Improveadjustment of lighting module orientationVSAvoidcompliance with statutory lighting requirements

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The lighting system is divided into multiple independently adjustable lighting modules (first lighting module and second lighting module), each with its own adjustment mechanisms (first adjustment device and second adjustment device). This segmentation allows individual modules to be adjusted without affecting the statutory compliance of other modules, resolving the contradiction between adjustment flexibility and regulatory compliance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lighting modules are designed with dynamic adjustment capabilities through mechanical connection devices that allow vertical and horizontal orientation changes. The first and second adjustment devices enable the system to dynamically adapt module orientations while maintaining the ability to provide complex light beams that meet statutory requirements through coordinated control of multiple modules.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple lighting modules are used to provide complex light beams, then the lighting functions are improved, but the control of light beam positions and orientations becomes more complex

Engineering Contradiction:

Improvelighting functionsVSAvoidcontrol of light beams

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mechanical connection device serves multiple functions: it connects the first and second lighting modules, provides vertical adjustment through the first adjustment device, provides horizontal adjustment through the second adjustment device, and maintains relative positioning. This multi-functionality reduces the need for separate control mechanisms for each degree of freedom, simplifying the overall control system while enabling complex lighting functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the orientation of each lighting module can be adjusted independently, then the adaptability is improved, but the structural complexity increases

Engineering Contradiction:

Improveorientation adjustmentVSAvoidmechanical structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment mechanisms are merged into a coordinated system where the first adjustment device (for vertical orientation) and the second adjustment device (for horizontal orientation) work together through the mechanical connection device. This merging of adjustment functions into an integrated mechanical structure reduces overall complexity compared to having completely independent adjustment systems for each lighting module.

Inventive Principle:

Principle #5Merging (Combining)
