Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If an internal loop antenna is used in the hearing device, then the device maintains a compact size, but the antenna efficiency and bandwidth are insufficient
Solution Approach 1:
The patent combines the antenna function with the existing coupling element (wire connecting behind-ear and in-ear portions) by integrating an electrically conducting element into it. This merging approach allows the coupling element to serve dual purposes: mechanical/electrical connection and wireless communication antenna, thereby improving antenna efficiency without increasing device volume
Solution Approach 2:
The coupling element is designed to perform multiple functions simultaneously: it acts as both the mechanical connector between device portions and the antenna for wireless communication. This multi-functionality eliminates the need for separate antenna structures, maintaining compact device size while achieving sufficient antenna performance
2Length of moving object
If the hearing device is made smaller than the wavelength, then the device meets size requirements, but the antenna bandwidth and efficiency are adversely affected
Solution Approach 1:
The patent extends the electrically conducting element of the antenna along the length of the coupling element, utilizing the longitudinal dimension to achieve sufficient antenna length for adequate bandwidth and efficiency. This dimensional approach allows the antenna to function effectively despite the overall compact device size
3Reliability
If external antenna solutions are used, then antenna efficiency is improved, but the device size and complexity increase
Solution Approach 1:
The patent merges the antenna function with the existing coupling element structure by integrating an electrically conducting element into it. This eliminates the need for separate external antenna components, thereby maintaining antenna efficiency while avoiding increased device complexity
Solution Approach 2:
The coupling element serves itself by performing dual functions: it provides the mechanical and electrical connection between device portions while simultaneously acting as the antenna for wireless communication. This self-service approach eliminates the need for additional dedicated antenna components
