Headband Assembly Spring Member Clamping Force Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headband assemblies for headphones often fail to provide a sufficient clamping force to maintain the headphones in place comfortably and securely on different head sizes and shapes while also being aesthetically pleasing.
Innovation Solution
A headband assembly featuring a continuous curved compliant spring member coupled with a cushion member and a spine, which is integrated with a cap to provide adjustable earcup positioning and a uniform appearance, using materials like biocompatible silicone and spring steel for comfort and clamping force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a rigid headband structure is used to provide sufficient clamping force, then the headphones can be securely maintained on the head, but the comfort and adaptability to different head sizes and shapes deteriorate
Solution Approach 1:
The headband incorporates a spring member that enables dynamic adjustment of the clamping force. The spring member can compress and expand to adapt to different head sizes and shapes while maintaining sufficient clamping force, transforming the rigid structure into a dynamic, adaptable system.
Solution Approach 2:
The spring member changes its physical state (compression/expansion) to adjust the clamping force parameter. This allows the headband to provide different levels of clamping force for different head sizes and shapes, resolving the contradiction between maintaining sufficient force and adapting to versatility.
2Stability of the object's composition
If a rigid headband structure is used to maintain secure positioning, then the headphones stay in place, but the comfort and visual appeal deteriorate
Solution Approach 1:
The headband uses a flexible spring member instead of a rigid structure. This flexible component can deform to match the contours of the user's head, providing both secure positioning and enhanced comfort, while also improving visual appeal through a more ergonomic design.
3Adaptability or versatility
If a complex adjustment mechanism is added to provide adjustable earcup positioning, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent combines the adjustment functionality into the existing headband structure by utilizing the spring member's inherent flexibility. This merging of adjustment capability with the basic headband structure provides adaptable earcup positioning without adding separate complex adjustment mechanisms.
