Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure lens retention mechanism is used, then lens stability during athletic activities is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is segmented into discrete functional elements: a spring element providing biasing force, a lock element with latches for engagement, and a release element for actuation. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity and reliability in lens retention during athletic activities.
Solution Approach 2:
The spring element automatically biases the lock element into the locked position without requiring external power or complex control systems. The mechanism self-locks when the lens is inserted, and the release element provides a simple manual override when needed, eliminating the need for electronic controls or multiple actuation stages.
2Ease of operation
If a kerf-like slotted spring lock mechanism is used, then ease of lens insertion is improved, but manufacturing precision requirements increase
Solution Approach 1:
The kerf-like slots are designed with specific dimensional parameters that balance ease of insertion with manufacturing feasibility. The slots are positioned and dimensioned to allow the lock element to flex open sufficiently for lens insertion while maintaining precise engagement surfaces for the latches and detents, accommodating standard manufacturing tolerances.
Solution Approach 2:
The lock element is designed as a dynamic component that flexes elastically within the kerf-like slots during lens insertion. This dynamic behavior allows the mechanism to accommodate minor variations in slot dimensions and latch positions, reducing the stringency of manufacturing precision requirements while maintaining reliable engagement.
3Adaptability or versatility
If interchangeable lens capability is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The lock element and receptor are designed as universal components that can accommodate various lens types through a standardized interface. The same spring element, lock element with latches, and release element work with different lens configurations, allowing the frame to serve multiple functions with interchangeable lenses without requiring separate mechanisms for each lens type.

Function Achieved in This Case
The solution provides a versatile and cost-effective means for interchangeable lenses, ensuring secure retention and ease of use, even during athletic activities.
Implementation Method 1
a kerf-like slotted spring lock. The kerf-like slotted spring lock releases under pressure to allow the insertion of a lens and once inserted, provides sufficient force to retain the lens in position

AI summary
A lens receptor that includes relief mechanism, such as a kerf-like slotted spring lock, that releases under pressure to allow the insertion of the lens and once inserted, provides sufficient force to retain the lens in position even during athletic activity. The lock includes an interior space that includes latches. The lens includes catches and detents that correspond to the latches. In operation, the lock is forced into the open position as the catches of the lens are forced to the backside of the latches, and as the lock closes, the latches are forced into the detents thereby securing the lens to the lock.
