Eyeglass Retainer Cinch Loop Adjusts Strap Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass retainers often interfere with the head or neck of the wearer due to the strap not being maintained in a fixed position, leading to discomfort and potential loss of the glasses.
Innovation Solution
An eyeglass retainer system comprising a first and second cinch with a base and a lace that forms loops to securely hold the temples of the eyeglasses, using flexible materials and adjustable beads for tension adjustment, preventing the strap from interfering with the head or neck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the strap of the eyeglass retainer is made adjustable and fixed in positions, then the comfort for the wearer is improved, but the device complexity increases
Solution Approach 1:
The retainer system incorporates adjustable straps with multiple fixed positions that can adapt to different wearer needs. The strap transitions from a static single-position design to a dynamic multi-position system, allowing the wearer to select the most comfortable configuration. This resolves the contradiction by making the device adaptable rather than fixed, improving comfort while maintaining reasonable complexity through standardized adjustment mechanisms.
Solution Approach 2:
The invention changes the positional parameter of the strap from a single fixed position to multiple discrete fixed positions. By providing several predetermined positions along the strap length, the system allows optimization of comfort parameters without requiring continuous adjustment mechanisms, thus balancing improved ease of operation with controlled device complexity.
2Ease of operation
If the strap is made longer to avoid interfering with the head or neck, then the comfort is improved, but the reliability of holding the eyeglasses decreases
Solution Approach 1:
The adjustable strap length allows the system to dynamically adapt between different effective lengths. When maximum holding reliability is needed, the strap can be positioned to create a shorter effective loop. When comfort is prioritized, the strap can be extended. This dynamic positioning capability resolves the contradiction by allowing optimization of both reliability and comfort based on specific usage conditions.
Solution Approach 2:
The strap is effectively segmented into multiple positionable sections through the adjustable mechanism. Rather than being a single continuous length, the functional strap length can be divided and reconfigured, allowing the portion that provides holding force to be optimized separately from the portion that contacts the wearer. This segmentation enables independent optimization of reliability and comfort parameters.
