Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If tight tolerances are required for positioning optical elements relative to light sources, then positioning precision is improved, but manufacturing complexity and costs increase
Solution Approach 1:
The patent introduces a positioning element as an intermediary component between the light source and the optical element. This positioning element provides reference surfaces and mechanical constraints that enable precise positioning without requiring tight tolerances on the sleeve itself. The positioning element acts as a mediator that transfers and stabilizes the spatial relationship between components.
Solution Approach 2:
The positioning element incorporates self-aligning features such as self-centering mechanisms and self-adjusting reference surfaces. These features enable the optical element to automatically position itself relative to the light source during assembly, eliminating the need for complex external alignment tools or procedures and reducing the skill level required for assembly.
2Manufacturing precision
If tight tolerances are required for positioning optical elements relative to light sources, then positioning precision is improved, but manufacturing costs increase
Solution Approach 1:
The positioning element serves as a cost-effective intermediary that provides precise positioning functionality without requiring expensive tight-tolerance machining on the sleeve. By concentrating the precision requirements on a dedicated positioning component rather than the entire assembly, manufacturing costs are reduced while maintaining positioning accuracy.
Solution Approach 2:
The patent segments the positioning function from the structural support function. The sleeve provides structural support with relaxed tolerances, while the positioning element provides precise positioning with concentrated tolerances. This segmentation allows each component to be manufactured independently with appropriate tolerances, reducing overall manufacturing cost.
3Manufacturing precision
If complex configurations are used to position optical elements, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The positioning element consolidates multiple positioning functions into a single intermediary component. Instead of using complex configurations involving multiple adjustment mechanisms and reference features distributed across multiple parts, the positioning element provides all necessary positioning functionality in one integrated component, simplifying the overall device configuration.
