Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesive material is used to attach lenses to the tubular body, then the lenses can be fixed in position, but the adhesive material damages the phosphor layer on LEDs and deteriorates from heat causing lens separation
Solution Approach 1:
The adhesive material is completely removed from the system. Instead of using adhesive to attach lenses to the tubular body, the patent uses a mechanical retention structure where the lens holder's retention portion physically secures the lens without any adhesive material, thereby eliminating the source of phosphor layer damage and heat deterioration
Solution Approach 2:
A lens holder is introduced as an intermediary component between the lens and the tubular body. This lens holder with its retention portion provides a mechanical interface that secures the lens in place without requiring adhesive material, thus protecting the LED phosphor layer while maintaining lens attachment stability
2Stability of the object's composition
If adhesive material is used to attach lenses, then lenses can be secured, but the adhesive deteriorates from LED heat causing separation of lenses from the tubular body
Solution Approach 1:
The adhesive material is completely removed from the system. Instead of using adhesive to attach lenses to the tubular body, the patent uses a mechanical retention structure where the lens holder's retention portion physically secures the lens without any adhesive material, thereby eliminating the source of phosphor layer damage and heat deterioration
Solution Approach 2:
The chemical bonding mechanism (adhesive) is replaced with a mechanical retention system. The lens holder with its retention portion provides a purely mechanical interface that secures the lens through physical engagement, eliminating the thermal deterioration issues associated with adhesive materials
