Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If LED chips are densely configured to increase light output, then light efficiency improves, but heat dissipation becomes more difficult
Solution Approach 1:
The electrode plates are patterned with multiple segmented regions (first electrode plate with first set of LED chips, second electrode plate with second set of LED chips) that are spatially separated. This segmentation allows heat from each LED chip group to be dissipated independently through its own electrode plate, preventing heat accumulation while maintaining high light output capacity.
Solution Approach 2:
The invention transitions from a single-plane LED configuration to a three-dimensional arrangement where LED chips are distributed across multiple electrode plates positioned at different spatial locations. The plastic shell maintains predetermined spacing between electrode plates, creating vertical and horizontal separation that enhances heat dissipation pathways without reducing light efficiency.
2Volume of moving object
If multiple LED chips are arranged closely to reduce module size, then device compactness improves, but heat dissipation efficiency deteriorates
Solution Approach 1:
The module is divided into multiple independent electrode plate units, each carrying a set of LED chips. This segmentation allows compact arrangement of multiple chip sets while providing separate heat dissipation pathways for each unit, preventing heat interference between closely positioned LED groups.
Solution Approach 2:
The plastic shell acts as an intermediary structure that maintains predetermined spacing between electrode plates while holding them in close proximity within the module. This intermediary component enables compact overall module size while ensuring adequate thermal separation through the insulating plastic material.
3Length of stationary object
If electrode plates are positioned close together to reduce spacing, then module compactness improves, but heat dissipation and light uniformity deteriorate
Solution Approach 1:
The invention optimizes the spacing parameter between electrode plates to a predetermined distance that balances two competing requirements: close enough to maintain module compactness, but far enough to ensure effective heat dissipation and uniform light distribution. This parameter optimization resolves the contradiction between compactness and thermal performance.
