Solution Overview
Problem
Existing acoustic apparatuses face challenges in providing optimal wearing comfort and stability due to inadequate support structures, leading to discomfort and potential device displacement during use.
Innovation Solution
The acoustic apparatus incorporates a support assembly with a first portion that is hung between the ear and the head, and a second portion that contacts the ear, applying a compressive force. This assembly includes a third portion that connects the first and second portions and adapts to the ear's thickness, forming a lever structure to enhance stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support structure is used, then the device complexity is reduced, but the wearing stability deteriorates
Solution Approach 1:
The support structure is divided into multiple portions (first portion, second portion, third portion) that can independently contact different parts of the ear. This segmentation allows each portion to be optimized for specific functions while collectively providing enhanced stability without excessive complexity.
Solution Approach 2:
The support structure extends into multiple spatial dimensions by having portions that contact the ear from different directions and depths. The third portion adapts to ear thickness, creating a three-dimensional support configuration that significantly improves wearing stability.
2Ease of manufacture
If a simple support structure is used, then the manufacturing cost is reduced, but the wearing comfort deteriorates
Solution Approach 1:
The support structure is divided into multiple portions that can be manufactured using standard processes and then assembled. This segmentation allows each portion to be optimized for comfort while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The third portion is designed to adapt to ear thickness by changing its dimensional parameters. This parameter adjustment capability provides customized comfort for different users without requiring complex manufacturing processes.
3Stability of the object's composition
If the support structure applies compressive force, then the wearing stability is improved, but the pressure on the ear increases
Solution Approach 1:
The compressive force is distributed across multiple portions contacting different areas of the ear. This segmentation of force application reduces localized pressure while maintaining overall stability through cumulative supportive effect.
Solution Approach 2:
The support structure distributes force across three-dimensional space by contacting the ear from multiple directions and depths. The third portion adapts to ear thickness, spreading the compressive force throughout the ear's volume rather than concentrating it at a single point.
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 described support structure significantly improves the wearing comfort and stability of the acoustic apparatus by distributing the weight evenly and providing a secure fit, thereby enhancing the overall user experience.
Implementation Method 1
The second contact point may be located between the first contact point and a first connection point between the first portion and the third portion to cause the first portion to form a lever structure with the second contact point as a fulcrum. A force provided by the head and directed toward an outside of the head at the second contact point may be converted by the lever structure into a force directed toward the head at the first connection point.
