Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless peripheral devices, such as mice, face challenges in power consumption due to the high energy requirements of components like radio transceivers, leading to short battery life and potential performance reductions when power-saving measures diminish capabilities.
Innovation Solution
Implementing an asymmetric reporting frequency scheme that reduces the activation frequency of high power-consuming components and increases data packet size, allowing for less frequent wireless transmissions while maintaining device performance by using larger data buffers and increased data transmission per cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wireless transceiver is activated frequently to maintain high performance and responsiveness, then device performance is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by using asymmetric reporting frequencies where the wireless transceiver is activated less frequently than internal components. The system reports wirelessly at a lower frequency while maintaining high-frequency internal processing, thereby reducing power consumption while preserving device performance through strategic timing of data transmissions.
Solution Approach 2:
The patent applies dynamics by implementing adaptive reporting frequencies that can adjust based on device state and requirements. The system dynamically adjusts the frequency of wireless transmissions versus internal component activation, allowing optimal balance between power consumption and performance based on real-time conditions.
2Use of energy by moving object
If the activation frequency of high power-consuming components is reduced to save power, then power consumption is reduced, but device responsiveness may be compromised
Solution Approach 1:
The patent segments the data transmission process into internal component communication and wireless transmission stages. By segmenting the reporting frequency asymmetrically, internal components operate at high frequency for responsiveness while wireless transmission occurs at lower frequency for power savings, resolving the contradiction between speed and energy consumption.
Solution Approach 2:
The patent implements asymmetry through asymmetric reporting frequencies where the frequency of internal data collection differs from the frequency of wireless transmission. This asymmetric approach allows the system to optimize for both responsiveness (high internal frequency) and power consumption (lower wireless frequency) simultaneously.
3Use of energy by moving object
If data packet size is increased to reduce transmission frequency, then power consumption is reduced, but data processing requirements increase
Solution Approach 1:
The patent changes the parameter of data packet size by implementing variable-length packets that adapt to the asymmetric reporting frequency scheme. By adjusting packet size parameters, the system reduces the number of transmissions while managing processing requirements through efficient data aggregation and compression techniques.
