Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If indirect positioning mode through radiator is used, then assembly is simplified, but positioning precision is low and light form effect is influenced
Solution Approach 1:
The invention extracts the positioning function from the radiator, which previously served dual purposes of heat dissipation and positioning. By removing the positioning function from the radiator and implementing direct positioning between optical elements and circuit board, the patent achieves high positioning precision without compromising assembly simplicity.
2Ease of manufacture
If base part and reflector main body are made of resin, then manufacturing is easier, but heat resistance is very low and service life is influenced
Solution Approach 1:
The invention employs composite material construction where the base part and reflector main body are made of heat-resistant materials (metal or high-temperature resistant polymer) rather than ordinary resin. This composite approach maintains manufacturing feasibility while significantly improving heat resistance and service life under high-temperature operating conditions.
3Device complexity
If radiator and circuit board are integrated pieces, then device complexity is reduced, but dimming function is lost and light form alignment is poor
Solution Approach 1:
The invention segments the integrated radiator-circuit board structure into separate components. The circuit board is designed as an independent component with positioning plugs that directly position optical elements, while the radiator serves solely for heat dissipation. This segmentation enables the circuit board to incorporate dimming structures and adjust reflector positions to achieve proper light form alignment.
4Manufacturing precision
If positioning plugs and sockets are used for direct positioning, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The positioning plugs and sockets are integrated into the existing circuit board and optical element structures, allowing these components to serve dual purposes: structural support and precise positioning. The circuit board's positioning plugs directly position the reflectors and light shields, eliminating the need for separate positioning mechanisms and reducing overall structural complexity.
