Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional pressing rings glued on inner wall are used to limit lenses, then lens stability is maintained, but outline dimension becomes large
Solution Approach 1:
The patent replaces the conventional mechanical pressing ring structure with a magnetic field-based adsorption system. Magnetic adsorption members are embedded in the lens barrel, interacting with magnetic components in the lens mounting brackets to provide holding force without requiring physical contact or large structural elements, thus reducing outline dimension while maintaining lens stability.
Solution Approach 2:
The patent changes the physical state and interaction mechanism from mechanical contact (pressing rings) to magnetic field interaction. By utilizing magnetic field strength parameters and distribution, the system achieves effective lens retention with smaller structural dimensions, resolving the contradiction between compact size and stability.
2Reliability
If extensive fixing portions are used to secure lenses, then lens reliability is improved, but radial dimension increases
Solution Approach 1:
The patent replaces extensive mechanical fixing portions with a magnetic adsorption system. The magnetic interaction between embedded magnets in the lens barrel and magnetic components in the lens mounting brackets provides secure lens retention without requiring large radial extensions or complex mechanical fastening structures.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary force to transmit the holding action from the lens barrel to the lenses. This magnetic mediation allows for compact structural design while maintaining reliable lens securing, as the magnetic field can exert force without physical contact or large structural components.
3Device complexity
If pressed structure with pressing rings is used, then lens assembly is simple, but device volume is large
Solution Approach 1:
The patent replaces the pressed structure with pressing rings by implementing a magnetic adsorption system. The lens mounting brackets with magnetic components interact with embedded magnets in the lens barrel to provide automatic holding force, eliminating the need for pressing rings and complex pressed assembly structures, thus reducing device volume while maintaining assembly simplicity.
Solution Approach 2:
The magnetic adsorption system provides self-holding capability through magnetic attraction between the lens barrel and lens mounting brackets. This self-service mechanism eliminates the need for external pressing structures, reducing overall device volume while maintaining simple assembly through the inherent magnetic retention force.
