Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design and manufacturing of hearing devices are complicated and costly due to the need to accommodate coil antennas, which are not universally used, requiring unnecessary space on the circuit board and in the housing, regardless of whether they are actually installed.
Innovation Solution
A hearing device with a switching module that includes a movable switching element with a hollow space for the coil antenna, allowing it to be integrated separately from the housing and circuit board, enabling flexible manufacturing and easy retrofitting without altering the device's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coil antenna is mounted on the circuit board inside the housing, then the inductive transmission function is achieved, but the design complexity and manufacturing cost increase due to non-optimized arrangement of electronic components
Solution Approach 1:
The coil antenna is extracted from the circuit board and housing structure, and mounted separately on the external surface of the housing. This separation allows the antenna to be added without affecting the internal arrangement of electronic components, thereby reducing design and manufacturing complexity while maintaining the inductive transmission function
2Adaptability or versatility
If space is allocated for the coil antenna on the circuit board and in the housing, then the antenna can be installed, but the manufacturing cost increases due to non-optimized component arrangement
Solution Approach 1:
The coil antenna is extracted from the internal housing structure and mounted on the external surface. This eliminates the need to reserve space within the housing and circuit board, allowing for optimized component arrangement and reduced manufacturing costs while maintaining the capability to install the antenna
Solution Approach 2:
The hearing device is segmented into functional modules: the main housing with optimized component arrangement, and the separately mounted coil antenna on the housing surface. This segmentation allows independent optimization of each module, reducing overall manufacturing cost while maintaining versatility
3Adaptability or versatility
If the housing and circuit board are designed with space for the coil antenna, then the antenna can be fitted, but the design costs increase due to additional fitting requirements
Solution Approach 1:
The coil antenna is extracted from the housing design and mounted on the external surface. This allows the housing and circuit board to be designed without dedicating space for the antenna, reducing design costs and complexity while maintaining antenna compatibility through external mounting
4Stability of the object's composition
If the coil antenna is integrated into the housing and circuit board, then the structure is unified, but the difficulty of manufacture increases
Solution Approach 1:
The coil antenna is extracted from the internal structure and mounted on the external housing surface. This separation simplifies manufacturing by allowing the housing and antenna to be produced independently and assembled separately, reducing the difficulty of manufacture while maintaining structural integrity
Solution Approach 2:
The device is segmented into the main housing unit and the separately mounted antenna. This segmentation allows each component to be manufactured independently using optimized processes, then assembled together, reducing overall manufacturing difficulty while maintaining unified structure
