Diving Mask Lens Mounting With Cam-Release Inner Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for assembling and disassembling diving masks are impractical, often requiring significant physical effort, risking damage to the mask components and potential injury to the user.
Innovation Solution
A cam-based locking/unlocking mechanism that induces elastic deformation of the inner frame, allowing the outer frame to be released from the inner frame through rotation, facilitated by a screwdriver for easy assembly and disassembly without damaging the mask components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If interlocking teeth are used to assemble the parts, then the assembly is secure, but it becomes difficult to disassemble and may damage the plastic parts
Solution Approach 1:
The patent employs a dynamic elastic deformation mechanism where the inner frame is temporarily deformed to release the interlocking teeth from their engaged position. This allows the same interlocking structure to provide strong assembly security while enabling easy disassembly through controlled elastic deformation, resolving the contradiction between secure assembly and easy disassembly.
2Reliability
If assembly screws are used to tighten the frames, then the seal is watertight, but the assembly process becomes laborious
Solution Approach 1:
The patent extracts the fastening function from traditional screws and replaces it with an elastic deformation-based locking mechanism. The inner frame's elasticity itself provides the clamping force needed for the watertight seal, eliminating the need for separate fastening components and simplifying the assembly process while maintaining seal reliability.
3Strength
If considerable effort is required to disassemble the mask, then the parts may be securely held, but it risks injuring the user's fingers
Solution Approach 1:
The patent introduces elastic deformation as an intermediary mechanism between the user's action and the part retention force. By deforming the elastic inner frame, the user can safely release the locking teeth without applying excessive force directly to the rigid components, thereby maintaining secure part retention while eliminating the risk of finger injury.
