Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If separate circuit carriers and optics are used for LED retrofitting in decorative lights, then energy efficiency is improved, but assembly complexity and alignment difficulty increase
Solution Approach 1:
The patent combines the circuit carrier with integrated LEDs and the optical system into a single unified lighting unit. This merging eliminates the need for separate assembly of multiple components, directly reducing assembly complexity while maintaining the energy-efficient LED technology. The circuit carrier and optics are integrated such that they function as one cohesive unit that can be installed as a single replacement component.
2Use of energy by moving object
If conventional light sources are replaced with LED lighting units, then energy consumption is reduced, but installation and replacement difficulty increases due to complex assembly requirements
Solution Approach 1:
By integrating the circuit carrier, LEDs, and optical system into a single lighting unit, the patent enables straightforward installation and replacement procedures. The unified design allows the entire LED assembly to be installed as one component, eliminating complex multi-step assembly processes and making retrofitting as easy as replacing a single light source.
Solution Approach 2:
The lighting unit is pre-assembled with all necessary components (circuit carrier, LEDs, optics) integrated and aligned before delivery to the customer. This preliminary assembly action eliminates the need for on-site alignment and complex installation procedures, allowing end-users to simply replace the pre-integrated unit as a single component.
3Manufacturing precision
If circuit carrier is directly attached to optics to form integrated unit, then alignment precision is improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the circuit carrier and optical system into a single manufacturing unit, allowing alignment to be established during the manufacturing process rather than during installation. This merging enables precise alignment to be built-in during production, eliminating the need for complex post-assembly alignment procedures while the integrated design simplifies the overall manufacturing process by treating the combination as one unit.
