Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are provided to support different frequency standards, then the hearing aid can communicate with various devices, but the weight, manufacturing costs, and installation space increase
Solution Approach 1:
The patent implements a single antenna structure that can operate across multiple frequency standards (Bluetooth, WLAN, UWB) by adjusting resonant frequencies through variable capacitors and inductors, eliminating the need for separate antennas for each standard. This multi-functional design reduces weight while maintaining compatibility with various communication protocols.
Solution Approach 2:
The patent combines multiple antenna functions into a single integrated antenna structure with two feed points and multiple resonant frequencies. By merging what would traditionally require separate antennas into one unified component, the design achieves weight reduction while supporting multiple frequency standards through electronic tuning.

4Use of energy by moving object
If the resonant frequency of the antenna is matched to the operating frequency, then energy consumption is reduced, but supporting multiple standards requires multiple antennas
Solution Approach 1:
The patent employs dynamic frequency tuning capabilities where the antenna's resonant frequency can be adjusted in real-time to match different operating frequencies for Bluetooth, WLAN, and UWB standards. This dynamic adaptation allows a single antenna to maintain optimal energy efficiency across multiple frequency standards by electronically reconfiguring its resonant characteristics.
Solution Approach 2:
The patent changes the electrical parameters (capacitance and inductance) of the antenna system to adjust its resonant frequency. By varying these parameters through variable capacitors and inductors, the antenna can be tuned to match different operating frequencies, enabling energy-efficient operation across multiple communication standards without requiring separate antennas.
