Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate spring elements and optical elements are used as in prior art, then the optical system can be adjusted, but the manufacturing and assembly costs increase
Solution Approach 1:
The spring element and optical element are merged into a single integrally formed component. The spring element is formed as an integral part of the optical element, eliminating the need for separate spring components and reducing assembly steps while maintaining the adjustable optical function.
Solution Approach 2:
The integrally formed spring-optical element serves multiple functions simultaneously: it provides the optical function (light transmission and focusing), the spring function (restoring force for adjustment), and the structural function (holding the optical element in position). This multi-functionality reduces the overall number of components needed in the system.
2Reliability
If multiple separate components are used for adjustment, then the optical system can be reset, but the resetting functionality is limited
Solution Approach 1:
The integrally formed spring element provides dynamic resetting capability. When the optical element is displaced from its initial position, the spring element automatically generates a restoring force that pushes the optical element back to its original position, enabling reliable resetting without additional mechanisms.
Solution Approach 2:
The spring element is designed to automatically return the optical element to its initial position without requiring external intervention or additional resetting mechanisms. The system serves itself by using the inherent elastic properties of the spring element to restore the optical configuration.
3Manufacturing precision
If traditional mounting arrangements are used, then the optical element can be positioned, but the sealing properties are compromised
Solution Approach 1:
The spring element is formed from a flexible material that can be elastically deformed. This flexibility allows the spring element to adapt to sealing surfaces and create effective seals while maintaining precise positioning of the optical element, overcoming the limitation of rigid traditional mounting arrangements.
