Wireless Headphone Parietal Temporal Bone Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audio reproducing hardware struggles to maintain position on a user's head during mobility activities, leading to degraded audio quality and reduced mobility potential due to dislocation during continuous or sporadic movements.
Innovation Solution
A wireless audio reproducing headphone with a headband featuring parietal and temporal elements that provide three concurrent points of contact on strategic areas of the user's head, utilizing a curvilinear extension to secure the device on the temporal and parietal bones, combined with customizable cushions and materials for optimal retention and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional headband design is used, then the headphone can be easily manufactured and worn, but the headphone dislocates during movement and cannot maintain position on the user's head
Solution Approach 1:
The headband is divided into multiple functional segments: a main body portion and separate parietal and temporal features. Each segment contacts different bones (parietal bone and temporal bone) to create multiple anchoring points, preventing dislocation during movement while maintaining a relatively simple overall structure.
Solution Approach 2:
The headband transitions from a single-plane contact design to a multi-dimensional contact system by adding the parietal feature that extends posteriorly to contact the parietal bone. This creates three-dimensional anchoring points (frontal, parietal, and temporal) that work together to maintain headphone position stability during various movements.
2Ease of operation
If the headband contacts only the frontal bone, then the structure remains simple, but the headphone cannot be controlled during movement
Solution Approach 1:
The headband is segmented into distinct contact features: a main body portion contacting the frontal bone, a parietal feature contacting the parietal bone, and temporal features contacting the temporal bones. This segmentation allows each feature to independently anchor to different skull regions, providing comprehensive control during movement without excessive complexity.
Solution Approach 2:
The parietal feature incorporates a curvilinear extension that conforms to the curvature of the parietal bone. This curved design enhances contact area and anchoring effectiveness during head movement, improving ease of operation while maintaining reasonable structural complexity.
3Reliability
If the headband uses a simple single-point contact design, then manufacturing is easy and comfort is maintained, but the headphone dislocates during continuous or sporadic movements
Solution Approach 1:
The single contact point is segmented into multiple contact points: frontal bone contact, parietal bone contact via the curvilinear extension, and temporal bone contact. This multi-point anchoring system significantly improves retention during continuous or sporadic movements while adding only moderate structural complexity.
Solution Approach 2:
The headband incorporates different materials with specific properties: a flexible main body portion for comfort and adaptability, and rigid or semi-rigid parietal and temporal features for stable bone contact. This composite approach enhances retention reliability while keeping the design practically manufacturable.

AI summary
A headphone can have at least one wireless audio reproducing element attached to a headband. The headband may have parietal and temporal features with the temporal feature contacting a user's temporal bone and the parietal feature having a curvilinear extension from the temporal feature that contacts a predetermined portion of a user's parietal bone.
