Wave-Shaped Temple Insert for Eyewear Comfort and Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eyewear often causes discomfort due to pressure points on the head and is not suitable for various head shapes, leading to poor retention and potential deformation or breakage.
Innovation Solution
The eyewear features wave-shaped temple inserts that distribute inward force and allow for rotation and bending, conforming to the head shape and reducing pressure points while maintaining secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional rigid temple assemblies are used, then structural strength is maintained, but comfort deteriorates due to pressure points on the head
Solution Approach 1:
The temple assembly is divided into multiple segments including a temple substrate, wave-shaped insert, and covered portion. The wave-shaped insert contains multiple spans that can independently deflect, allowing the temple to conform to head contours while maintaining overall structural integrity through the distributed segmented structure.
Solution Approach 2:
The temple assembly incorporates a wave-shaped insert with multiple spans that act as a flexible element within the temple substrate. This flexible structure allows the temple to bend and conform to the user's head shape, distributing pressure along multiple contact points rather than concentrating force at single points, thereby improving comfort while maintaining strength.
2Object-affected harmful factors
If temple assemblies are designed for large heads, then comfort is improved, but retention deteriorates on narrow heads
Solution Approach 1:
The temple assembly employs a dynamic structure with a wave-shaped insert that can deflect and adapt to different head sizes and shapes. The multiple spans in the wave-shaped insert allow the temple to adjust its configuration based on the user's head dimensions, providing both comfort for larger heads and secure retention for narrower heads through its ability to conform dynamically.
Solution Approach 2:
The wave-shaped insert changes its deflection parameters based on the applied load and head shape. For larger heads, the temple deflects more to accommodate the increased circumference, while for narrower heads, the deflection is reduced to maintain secure retention. This parameter adaptation allows a single temple design to serve multiple head types effectively.
3Object-affected harmful factors
If temple assemblies are made flexible to conform to head shapes, then comfort is improved, but structural strength deteriorates
Solution Approach 1:
The temple assembly uses a composite structure combining a temple substrate, wave-shaped insert, and covered portion. This composite design allows the wave-shaped insert to provide flexibility for comfort while the temple substrate and covered portion maintain structural strength. The combination of these different elements creates a temple assembly that is both comfortable and strong.
4Object-affected harmful factors
If wave-shaped inserts with multiple spans are used, then comfort is improved through force distribution, but device complexity increases
Solution Approach 1:
The wave-shaped insert is nested within the temple substrate, with multiple spans contained within the overall temple assembly structure. This nesting approach allows the complex wave-shaped structure to be integrated into the temple without significantly increasing external dimensions or apparent complexity, while still providing the comfort benefits of force distribution across multiple contact points.
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 solution provides comfort and secure retention of eyewear on different head shapes, allowing for wear with additional equipment like helmets or headphones without causing discomfort.
Implementation Method 1
The horizontal span is configured to dictate the deflection of a first portion of the temple substrate and enable rotation of the first portion of the temple substrate about the horizontal span. The vertical portion is configured to dictate a torsional stiffness of a second portion of the temple assembly.

AI summary
An aspect includes a temple assembly that is configured to retain one or more lenses relative to a head of a user. The temple assembly may include a temple substrate and an insert. The temple substrate may be comprised of one or more polymers. The insert may be located at least partially within the temple substrate. The insert is configured to impose a spring force against the head of the user and is configured to allow at least a portion of the temple substrate to rotate axially about at least a portion of the insert such that the portion of the temple substrate deforms relative to the insert and at least partially independently of the insert.
