Engineering Contradiction Analysis
1Reliability
If the optical lens is polished directly without extending the second main surface, then the polishing process is simple and quick, but the polishing tool suffers premature damage due to sharp edges
Solution Approach 1:
A support device is introduced as an intermediary element between the optical lens and the polishing tool. This support device extends the second main surface of the lens, providing a protective barrier that prevents the polishing tool from直接接触 the sharp edges of the lens. The support device absorbs the mechanical stress and wear that would otherwise damage the polishing tool, thereby extending tool lifespan while maintaining a relatively simple overall system architecture.
Solution Approach 2:
The support device is pre-positioned and secured to the optical lens before the polishing process begins. By extending the second main surface in advance, the sharp edges are protected from the outset, preventing premature tool damage before the polishing operation commences. This preliminary protective measure ensures the polishing tool can complete its full operational life without encountering damaging sharp edges.
2Duration of action of moving object
If a support device is introduced to extend the second main surface, then the polishing tool lifespan is extended, but the device complexity increases
Solution Approach 1:
The support device serves as a mediating component that extends the second main surface of the optical lens. This intermediary structure protects the polishing tool from sharp edges while maintaining operational simplicity. The support device can be made from materials like foam or elastomers that provide the necessary structural extension without adding excessive complexity to the mounting system.
Solution Approach 2:
The support device changes the geometric parameters of the lens assembly by extending the second main surface. This parameter change creates a protective overhang that prevents the polishing tool from contacting the sharp edges. By modifying the surface extension parameter rather than changing the fundamental polishing mechanism, the solution extends tool life without significantly increasing system complexity.
3Reliability
If the support device contact surface is covered with a membrane, then the polishing tool wear is reduced, but the manufacturing complexity increases
Solution Approach 1:
The support device combines multiple materials with complementary properties: a base material (such as foam or elastomer) provides structural support and surface extension, while a membrane coating (such as rubber or polymer film) provides a protective, low-friction interface with the polishing tool. This composite structure reduces polishing tool wear through the membrane's protective properties while keeping the overall device manufacturable through standard composite material fabrication techniques.
Solution Approach 2:
A thin membrane film is applied to the contact surface of the support device. This flexible film provides a protective barrier that reduces wear on the polishing tool by preventing direct contact between the tool and the potentially sharp edges or rigid support device surface. The thin film nature of this solution minimizes manufacturing complexity while effectively extending tool lifespan.
