Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If incandescent light bulbs are used, then light is produced through simple resistive heating, but energy efficiency is poor and bulb lifespan is short
Solution Approach 1:
The patent replaces the traditional incandescent resistive heating mechanism with LED light emitting diodes that convert electrical energy directly to light through electroluminescence, eliminating the inefficient thermal conversion process and dramatically improving energy efficiency
Solution Approach 2:
The invention changes the fundamental operating parameters from thermal radiation (incandescent) to electroluminescence (LED), operating at much lower temperatures and voltages while producing comparable or superior light output with significantly reduced energy consumption
2Illumination intensity
If LED light sources are arranged in complex geometric configurations, then light distribution uniformity is improved, but structural complexity increases
Solution Approach 1:
The patent divides the LED array into multiple independent modules, each forming a geometric shape (triangle, square, rectangle, hexagon, or octagon), allowing complex light distribution patterns to be achieved through simple repeating units that can be manufactured and assembled independently
Solution Approach 2:
The invention transitions from planar LED arrangements to three-dimensional geometric configurations with LEDs positioned at vertices and along edges of polyhedral structures, enabling superior light distribution uniformity by utilizing spatial dimensionality to optimize illumination patterns from multiple angles
3Reliability
If frames with consecutive conductive and insulating segments are used, then electrical connection reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs frames constructed from composite structures combining conductive and insulating segments in alternating sequences, where the insulating segments prevent unwanted electrical pathways while conductive segments provide necessary electrical connections, achieving reliable electrical isolation and connection simultaneously
Solution Approach 2:
The insulating segments act as intermediary elements between conductive segments, preventing direct electrical contact where isolation is needed while allowing mechanical continuity of the frame structure, thus mediating between electrical connection requirements and structural integrity
