Eyewear Strap with Bendable Transition Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear with a rigid arc-shaped strap struggles to accommodate diverse user head shapes and hairstyles, leading to interference and instability in the snap-together bridge connection, causing difficulties in fitting and secure wear.
Innovation Solution
Incorporating transition segments with a wire core that can be bent to change shape, allowing the arc-shaped base to adjust its position along the user's head, ensuring a secure and comfortable fit by being flexible enough to conform to individual head shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid arc-shaped base is used in the strap, then the strap can maintain its configured orientation and structural stability, but it cannot adapt to diverse user head shapes and hairstyles, causing interference and connection instability
Solution Approach 1:
The arc-shaped base is divided into multiple segments (first arc-shaped segment and second arc-shaped segment) that can move relative to each other. This segmentation allows the base to change its configuration from a fixed rigid structure to a flexible multi-segment structure that can adapt to different head shapes while maintaining structural stability through controlled segment movement.
Solution Approach 2:
The arc-shaped base transitions from a static rigid structure to a dynamic structure where segments can change position relative to each other. The base can dynamically adjust its curvature and orientation to accommodate different head shapes and hairstyles, while the temples and connectors provide dynamic adjustment capabilities to maintain proper positioning during wear.
2Adaptability or versatility
If the arc-shaped base is made springy and bendable, then it can conform to user head shapes, but it may lose its configured orientation and require users to adapt to the eyewear rather than vice versa
Solution Approach 1:
The arc-shaped base incorporates dynamic segments that can be intentionally repositioned by the user during fitting. The springy segments allow the base to conform to head shapes while maintaining enough structural memory to return to a configured orientation, enabling both adaptability and ease of operation through controlled flexibility.
Solution Approach 2:
The physical parameters of the arc-shaped base (curvature, segment spacing, orientation) can be changed by the user during fitting to match their head shape. The springy segments allow parameter adjustment while maintaining structural integrity, enabling the base to adapt to different head shapes without requiring users to adapt to a fixed configuration.
3Reliability
If the releasable connectors are designed to snap together securely, then the eyewear maintains a stable connection when worn, but they may resist joinder and snap apart easily when users have diverse head shapes
Solution Approach 1:
The temples are designed as telescoping structures that can dynamically adjust their length, allowing the connectors to reach each other properly regardless of head shape variations. This dynamic adjustment capability ensures reliable connection stability while maintaining compatibility with diverse head shapes and sizes.
Solution Approach 2:
The strap is segmented into multiple adjustable components (parallel legs, arc-shaped segments, transition segments) that can independently adjust to accommodate different head shapes. This segmentation allows the connectors to maintain secure joining across various user anatomies by distributing the adaptation requirements across multiple flexible elements rather than requiring a single rigid structure.
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 flexible transition segments enable the eyewear to adapt to various head shapes and hairstyles, maintaining a secure connection and preventing the releasable connectors from snapping apart, thus ensuring a comfortable and secure fit for users with different head sizes and styles.
Implementation Method 1
the wire core being bendable by a user causing the transition segments to change from its first shape to a second shape and to maintain its second shape unless bent further by a user

AI summary
The present eyewear includes a pair of lenses, a pair of releasable connectors connected to respective inner ends of the lenses, temples pivotally connected to respective outer ends of the lenses and a rigid strap connected between the rear ends of the temples. The strap is further characterized as having parallel legs connected to the rear ends of the temples, transition segments having a first shape extending from the substantially parallel legs to an arc-shaped base which extends along the back of the user's head when worn. The transition segments are bendable by a user causing them to change from their first shape to a second shape and to maintain the second shape unless bent further by the user.
