Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lens is exposed to protect the device functionality, then the device can perform its optical function, but the lens is vulnerable to dust, debris, scratches, and cracks
Solution Approach 1:
The protective system is divided into multiple segments: a removable lens cap for basic protection, an anti-reflection element for optical control, and a sliding member with apertures for selective light control. This segmentation allows each component to perform its specific function independently while working together to solve the contradiction between protection and functionality.
Solution Approach 2:
The sliding member can dynamically move between different positions to change the aperture configuration, allowing the system to adapt between fully protected state and various functional states. The elastic cord provides dynamic retention, automatically securing the cap when attached while allowing easy removal when needed.
2Object-affected harmful factors
If the lens is covered to prevent reflections and accidental light emissions, then the user's location is concealed, but the device cannot perform its optical function
Solution Approach 1:
The anti-reflection element serves as an intermediary component between the lens and the external environment. It selectively blocks harmful reflections and accidental light emissions while allowing the optical function to proceed when the sliding member is in the appropriate position. The apertures in the sliding member act as controlled intermediaries for light passage.
Solution Approach 2:
The anti-reflection element provides localized optical control by treating only the specific areas where reflections occur, while the sliding member with its apertures provides selective local openings for necessary light passage. This localized approach maintains overall device functionality while addressing specific harmful effects.
3Reliability
If a protective cover is added to the lens, then the lens is protected from physical damage, but the device complexity increases
Solution Approach 1:
The lens cap assembly is designed as a universal protective system that can be applied to various optical devices. Each component serves multiple functions: the cap provides physical protection and secures via elastic cord, the anti-reflection element controls reflections and can serve as a structural component, and the sliding member provides both protection and optical control through its aperture configuration. This multi-functionality reduces the need for separate components.
Solution Approach 2:
The invention merges multiple protective and control functions into a single integrated assembly. The cap, anti-reflection element, and sliding member are combined into one removable unit that attaches to the device together, simplifying the attachment process while providing comprehensive protection and control capabilities that would require multiple separate components otherwise.
