Eyewear Accessory Attachment via Elastic Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear accessory attachment features require significant time and effort for attachment and detachment, limiting customization and personalization options.
Innovation Solution
The design of eyewear frames with accessory attachment openings that include a tapered shape and elastic deformable materials, allowing for easy ingress and egress of accessories in a perpendicular direction, with a keyhole shape that secures accessories through a combination of receiving and mounting portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple accessory attachment features are used, then device complexity is reduced, but ease of operation deteriorates due to significant time and effort needed for attachment and detachment
Solution Approach 1:
The accessory attachment feature incorporates an elastic deformable material that dynamically changes its physical state during attachment and detachment operations. The material deforms elastically to allow accessory insertion and returns to its original shape to secure the accessory, providing adaptive operation without complex mechanical components.
Solution Approach 2:
The elastic deformable material changes its physical parameters (shape, volume, stiffness) in response to applied forces during accessory attachment and detachment. This parameter change enables the simple structure to achieve complex functionality through material property variations rather than mechanical complexity.
2Reliability
If secure accessory attachment is achieved, then reliability is improved, but ease of operation deteriorates due to difficulty in detachment
Solution Approach 1:
The elastic deformable material provides dynamic attachment security - it maintains strong holding force when the accessory is stationary (reliability) but allows easy detachment when force is applied (ease of operation). The material transitions between constrained and deformed states based on operational needs.
Solution Approach 2:
The attachment and detachment process follows a periodic cycle where the elastic material is deformed during attachment, holds the accessory securely, and then returns to its original shape during detachment. This periodic deformation and recovery enables both secure attachment and easy removal.

AI summary
An article of eyewear includes a frame. The frame includes a front frame defining a left aperture and a right aperture. The frame also includes a left temple arm and a right temple arm. The left temple arm is supported by the front frame and the right temple arm is supported by the front frame. The frame further includes an accessory attachment opening adapted to detachably receive an accessory. The accessory attachment opening extends through a portion of the frame in a thickness direction. The accessory attachment opening includes an open side adapted to facilitate ingress and egress of the accessory from the accessory attachment opening in a direction substantially perpendicular to the thickness direction.
