Eyeglass Temple With Retractable Support Wire Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support wires for glasses are inconvenient as they require separate handling and can cause hindrances when storing or wearing glasses, often resulting in knots that are difficult to manage.
Innovation Solution
A temple design with a serpentine-shaped housing that integrates a support wire, allowing it to be easily extracted and retracted using elastic means, eliminating the need for separate handling and preventing knotting, with features like ultrasonic welding and adjustable locking mechanisms for secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support wire is entirely separated from the temples, then the wire can be freely handled and adjusted, but the wire can constitute a hindrance, get knotted, and require separate handling and storage
Solution Approach 1:
The patent merges the support wire with the temple structure by integrating the wire into a housing within the temple. The wire is no longer a separate component but is combined with the temple through the housing mechanism, allowing automatic retraction and eliminating the need for separate handling and storage of the wire.
Solution Approach 2:
The support wire is nested within the housing of the temple. The wire can be extracted when needed and automatically returns to its nested position within the housing when not in use, similar to a nested doll structure where one element is contained within another.
2Ease of operation
If the wire is made visible and accessible for easy extraction, then the user can easily access the wire, but the wire becomes visible and creates a less aesthetic appearance
Solution Approach 1:
The opening in the housing acts as an intermediary element that allows wire extraction while maintaining aesthetic appearance. The opening is positioned and sized to enable functional access to the wire while remaining imperceptible or minimal in visual impact, serving as a mediator between functionality and aesthetics.
3Volume of moving object
If the temple is made compact and integrated, then the overall size is reduced and aesthetics are improved, but the housing for the wire becomes more constrained in space
Solution Approach 1:
The housing for the wire is configured in a serpentine pattern with multiple loops and bends, utilizing three-dimensional space efficiently. This allows the housing to accommodate a sufficient length of wire within the constrained volume of the compact temple structure by distributing the wire length across multiple spatial dimensions rather than requiring a single long linear space.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The temple design ensures the wire is always attached to the glasses, invisible externally, and allows for easy neck support and storage without knotting, providing a convenient and organized solution for managing the support wire.
Implementation Method 1
means for returning the wire inside its housing when it is not used, as an elastic band, a spring or other means which allows the recovery of the wire
Implementation Method 2
The parts are shaped in such a way to form complementary parts of a wall which delimitates a cavity... in accordance with the invention, by adopting the idea of providing a temple in two parts harmoniously coupled, for example by ultrasonic welding
