Eyewear Temple Assembly with Metal Insert for Secure Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear designs that combine with additional equipment, such as helmets and hearing protection, often cause user discomfort and limit functionality due to improper pressure distribution and interference.
Innovation Solution
The eyewear features temple assemblies with a metal insert and a pliable covered portion, configured to apply a spring load for secure fitting and reduce pressure discomfort, allowing for comfortable wear with additional equipment while maintaining functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eyewear is permanently attached to helmet or hearing protection equipment, then the eyewear can be securely held in place, but user comfort is reduced and functionality is limited
Solution Approach 1:
The temple assembly is divided into separate functional components: a temple substrate for structural support, a spring mechanism for adjustable pressure, and a covered portion for comfort. This segmentation allows each component to be optimized independently, achieving secure fit without permanent attachment.
Solution Approach 2:
The spring mechanism provides dynamic, adjustable pressure distribution along the temple assembly. This allows the eyewear to adapt to different head shapes and sizes while maintaining comfort, eliminating the need for permanent attachment to helmets or hearing protection.
2Adaptability or versatility
If eyewear uses short temple pieces or deformable temple pieces to fit with additional equipment, then the eyewear can be worn with helmets and hearing protection, but user comfort is reduced and functionality is limited
Solution Approach 1:
The covered portion is specifically designed with different material properties than the temple substrate. The covered portion uses softer, more compliant material to distribute pressure locally behind the ear, while the temple substrate maintains structural rigidity for compatibility with helmets and hearing protection.
Solution Approach 2:
The temple assembly combines different materials with complementary properties: a rigid temple substrate for structural integrity and compatibility with protective equipment, and a soft covered portion for pressure distribution and user comfort. This composite structure enables both adaptability and comfort simultaneously.
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 design ensures comfortable and secure fit of eyewear with additional equipment, reducing discomfort and maintaining functionality, enabling wear with head and hearing protection without interference.
Implementation Method 1
The metal insert is configured to impose a spring load against a head of a user to secure the eyewear to the head

AI summary
An example embodiment includes eyewear. The eyewear includes a lens, a brow piece, and two temple assemblies. The brow piece is configured to secure the lens. The two temple assemblies are coupled to the brow piece by two hinges. Each temple assembly includes a temple substrate, a covered portion, and a metal insert. The covered portion is formed on the temple substrate. The metal insert is located within the temple substrate. The metal insert is configured to impose a spring load against a head of a user to secure the eyewear to the head.
