Motion-Based Function Restriction in Electronic Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices lack effective functionality restriction mechanisms based on user movement states, potentially leading to unsafe or distracting operations during certain activities.
Innovation Solution
Incorporating an acceleration sensor to detect movement states and a controller to restrict device functions accordingly, such as limiting functionality during walking or vehicle use to prevent user distraction and ensure safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functions are restricted during movement, then safety and distraction reduction are improved, but device versatility and user convenience deteriorate
Solution Approach 1:
The function restriction policy is dynamically adjusted based on detected movement states. The system transitions between different restriction levels (e.g., from full functionality during stationary use to restricted functionality during movement), allowing the device to adapt its operational characteristics to current user conditions rather than applying static restrictions
Solution Approach 2:
The system changes the operational parameters of the device by modifying which functions are available based on movement detection. When movement is detected, specific functions are restricted while others remain available, creating a parameter-based control mechanism that balances safety with functional versatility
2Object-affected harmful factors
If function restriction is implemented, then distraction reduction is improved, but ease of operation deteriorates
Solution Approach 1:
The system continuously monitors movement through sensors and provides feedback to the controller, which automatically adjusts function availability. This closed-loop feedback mechanism ensures that restrictions are applied only when movement is detected, maintaining ease of operation during stationary use while preventing distraction during movement
Solution Approach 2:
The device autonomously detects movement states and applies appropriate function restrictions without requiring user input or manual configuration. The system self-regulates its operational characteristics based on sensor data, eliminating the need for users to manually manage function availability
