Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art hearing aid devices are difficult for users to operate, especially when worn, due to complex battery door mechanisms and on/off functions.
Innovation Solution
A hearing aid device with a rotably mounted battery drawer that incorporates a finger engagement portion for easy opening and closing, serving as both a battery placement mechanism and a push button for on/off switching, utilizing a spring mechanism and nail grip member for simplified operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex battery door mechanism is used to secure the battery, then the battery is held firmly, but the device becomes difficult to operate especially when worn
Solution Approach 1:
The patent combines the battery door and on/off switch into a single integrated component. The battery door serves dual functions: securing the battery through its closed position and activating the on/off function through a push button mechanism. This merging eliminates the need for separate mechanisms, reducing operational complexity while maintaining reliable battery securing.
Solution Approach 2:
The battery door is designed as a multi-functional element that simultaneously performs mechanical securing of the battery and electrical switching functions. The same component that holds the battery in place also acts as the on/off switch when pressed, making it a universal element that handles multiple critical functions with a single structure.
2Adaptability or versatility
If separate mechanisms are provided for battery door operation and on/off function, then each function can be optimized, but the overall device complexity increases
Solution Approach 1:
The patent merges the battery door mechanism and on/off switch into a single integrated assembly. The battery door structure incorporates a push button that directly actuates the switching mechanism, eliminating the need for separate components and reducing overall device complexity while maintaining functional versatility.
Solution Approach 2:
The battery door is designed as a universal component that performs both mechanical retention and electrical switching functions. This multi-functionality approach allows a single component to handle multiple tasks that would traditionally require separate mechanisms, thereby reducing complexity without sacrificing adaptability.
3Ease of operation
If a push button mechanism is integrated into the battery door, then on/off function is simplified, but the battery door structure becomes more complex
Solution Approach 1:
The push button mechanism is merged directly into the battery door structure, using the door itself as part of the switching mechanism. This integration allows the on/off function to be activated simply by pressing the battery door, simplifying operation while the added structural complexity is minimized through the merging approach.
