Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all biological signals are processed through multiple electrodes, then comprehensive user input is achieved, but computation and power consumption increase
Solution Approach 1:
The patent segments the biological signal processing by dividing electrodes into multiple groups, where each group is responsible for processing specific types of biological signals. This segmentation allows the system to activate only the necessary electrode groups for each control operation, reducing overall power consumption while maintaining comprehensive input capability.
Solution Approach 2:
The patent implements dynamic channel activation where the system selectively activates or deactivates electrode channels based on the current control context. When a specific control operation is detected, only the relevant channels are activated, and irrelevant channels are deactivated, making the system adaptive and energy-efficient.
2Adaptability or versatility
If multiple electrode channels are continuously active, then all biological signals can be received, but computation efficiency decreases
Solution Approach 1:
The patent performs preliminary detection of the control context before activating electrode channels. By first detecting what type of control operation is needed, the system can pre-determine which electrode channels should be activated, avoiding unnecessary computation and signal processing for irrelevant channels.
Solution Approach 2:
The patent changes the operational parameters of the electrode system by dynamically adjusting which channels are active based on the detected control context. This parameter change optimizes computation efficiency by processing only the necessary biological signals rather than all possible signals continuously.
3Use of energy by moving object
If context-based selective signal reception is implemented, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The patent creates a universal control framework where the context detection mechanism and channel activation logic can handle multiple different control operations through a single unified system. This multi-functional approach manages complexity by providing a general-purpose solution rather than separate dedicated circuits for each control type.
