Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with fixed screen positions require users to manually adjust the screen to be within their sight range, affecting the user experience.
Innovation Solution
A wearable device with at least two screen display areas and an inertial sensor that determines the screen display area corresponding to the user's sight range based on measured actions, such as wrist raising or turning, and automatically lights up the appropriate screen area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen display area is fixed at a specific position, then the device structure is simple, but the user cannot view content conveniently when the screen is not within their sight range
Solution Approach 1:
The screen display area is transformed from a fixed position to a movable configuration. The wearable device includes multiple screen display areas that can be selectively activated at different positions (front surface, rear surface, left side, right side) based on real-time detection of user wrist posture, enabling dynamic adaptation to user needs while maintaining operational simplicity
Solution Approach 2:
The system automatically determines the appropriate screen display area based on inertial sensor detection of user wrist posture. The processor selectively activates the corresponding screen display area without requiring manual user input or adjustment, allowing the device to serve itself by autonomously adapting to user positioning
2Adaptability or versatility
If multiple screen display areas are provided at different positions, then the adaptability to user sight range is improved, but the device complexity increases
Solution Approach 1:
The display system is segmented into multiple independent screen display areas located at different positions (front surface, rear surface, left side, right side). Each screen display area can be independently controlled and activated based on real-time detection of user wrist posture, enabling selective display optimization without requiring all screens to be always active
Solution Approach 2:
The system changes the operational parameters of different screen display areas based on detected wrist posture. The processor determines which screen display area should be activated by analyzing inertial sensor data, dynamically adjusting the display configuration to match the user's current position and viewing angle requirements
3Ease of operation
If the screen automatically adjusts based on user action, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The inertial sensor continuously monitors user wrist posture in a periodic manner, and the processor selectively activates screen display areas based on detected posture changes. This periodic detection combined with selective activation ensures that energy is consumed only when and where needed, rather than continuously powering all display areas
Solution Approach 2:
The system uses inertial sensor data to automatically determine user posture and selectively activate the appropriate screen display area without requiring continuous user input. This self-service mechanism reduces the need for manual screen adjustment operations while optimizing energy consumption by activating only the necessary display area
