Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices generate noise due to circuit-related or mechanical characteristics, particularly during periodic communication, which can be audible and disturb users.
Innovation Solution
An electronic device equipped with a processor that identifies whether it is worn and the function being executed, and adjusts the output power of its communication module accordingly to minimize noise generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication module operates at high output power to maintain communication quality, then communication reliability is improved, but internal noise increases and disturbs the user
Solution Approach 1:
The patent applies dynamics by making the communication module's output power adjustable rather than fixed. The processor dynamically changes the output power level based on real-time detection of wear state and active function, allowing the system to optimize between communication reliability and noise generation for each operating condition
Solution Approach 2:
The patent changes the operational parameter (output power) of the communication module based on detected conditions. When wear state and function indicate low noise risk, the system reduces output power to minimize noise; when communication quality is prioritized, it increases output power to maintain reliability
2Reliability
If the communication module continuously operates to maintain connectivity, then communication availability is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action by activating the communication module only during specific periods when wear state and function indicate it is necessary. Rather than continuous operation, the module operates periodically based on detected conditions, reducing overall energy consumption while maintaining availability when needed
Solution Approach 2:
The patent applies dynamics by making the communication module's operational state adjustable rather than fixed. The processor dynamically changes the output power level based on real-time detection of wear state and active function, allowing the system to optimize between communication reliability and noise generation for each operating condition
3Object-generated harmful factors
If the device reduces communication module output power to minimize noise, then user disturbance is reduced, but communication quality deteriorates
Solution Approach 1:
The patent changes the operational parameter (output power) of the communication module based on detected conditions. When wear state and function indicate low noise risk, the system reduces output power to minimize noise; when communication quality is prioritized, it increases output power to maintain reliability
Solution Approach 2:
The system implements feedback by continuously monitoring wear state and active function, then using this information to adjust communication module output power. The processor receives feedback about the current operating conditions and modifies the communication parameters accordingly to balance noise reduction with communication quality
