Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the object navigation device has a symmetric shape (cylindrical or rod-shaped) without specific marks, then the device structure is simple and manufacturing is easier, but the user cannot easily determine the correct direction of the navigation device
Solution Approach 1:
The navigation device automatically determines its own orientation by detecting the touch object's orientation through the touch sensing surface. The control circuit sets the device direction based on the detected touch condition, allowing the device to self-configure without requiring external markings or manual orientation setup.
Solution Approach 2:
The device changes its operational parameters (direction setting) based on the detected touch conditions. By analyzing the number, position, shape, and tilting angle of touch regions, the control circuit dynamically adjusts the navigation direction to match the user's intended orientation.
2Device complexity
If the object navigation device has a fixed direction, then the device structure is simple, but the device cannot adapt to different hand modes and touch configurations
Solution Approach 1:
The navigation device transitions from a static fixed-direction design to a dynamic orientation system. The touch sensing surface continuously detects touch object characteristics, and the control circuit dynamically adjusts the device direction based on real-time touch conditions, enabling adaptation to different hand modes and usage scenarios.
Solution Approach 2:
The touch sensing surface serves multiple functions: detecting touch presence, determining touch object orientation, and providing input for direction control. This multi-functional approach allows the device to adapt to various usage scenarios without requiring separate components for each function.
3Adaptability or versatility
If the object navigation device uses a touch sensing surface to automatically set direction, then the adaptability to different hand modes is improved, but the device complexity increases
Solution Approach 1:
The patent combines the touch sensing function and direction control function into an integrated system. The touch sensing surface and control circuit work together to automatically determine and set the navigation direction, merging multiple functions into a unified operational mechanism that reduces the need for separate components.
