Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power supplies are used for each LED fixture, then power distribution is achieved, but installation and maintenance convenience deteriorates
Solution Approach 1:
The patent combines multiple power supplies into a single centralized power facility that can serve multiple LED fixtures simultaneously. This consolidation reduces the number of separate power supplies needed, thereby simplifying installation and maintenance while still achieving reliable power distribution across the lighting system.
Solution Approach 2:
The centralized power facility is designed to perform multiple functions: it provides power distribution to multiple fixtures, incorporates heat dissipation capabilities through integrated fins, and includes shielding channels to protect LEDs from heat. This multi-functional design eliminates the need for separate dedicated power supplies for each fixture.
2Device complexity
If power facility is integrated into housing, then system complexity is reduced, but heat dissipation becomes more difficult
Solution Approach 1:
The patent merges the power facility with the housing structure by integrating heat dissipation fins directly into the housing. This combination reduces system complexity by eliminating separate heat dissipation components while effectively managing heat through the integrated fin structure.
Solution Approach 2:
The power facility is nested within the housing structure, with heat dissipation fins integrated into the housing walls. The shielding channel is also nested within the housing to protect LEDs from heat generated by the power facility, creating a compact nested arrangement that simplifies the overall system.
3Object-affected harmful factors
If shielding channel is provided for LEDs, then LED protection from heat is improved, but device complexity increases
Solution Approach 1:
The shielding channel is merged with the housing structure rather than being a separate component. The housing serves dual purposes: providing structural support and housing the shielding channel that protects LEDs from heat. This integration reduces device complexity while maintaining effective heat protection.
