Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If skin sensation stimulation is used for notification, then visual icons are eliminated, but erroneous operations and camera shake occur
Solution Approach 1:
The patent replaces skin sensation stimulation with a reaction force generation mechanism that provides tactile feedback through controlled mechanical resistance during operation unit manipulation. This substitution eliminates the harmful effects of skin sensation stimulation while maintaining non-visual notification capabilities through tactile means.
Solution Approach 2:
The system implements feedback by generating reaction forces that correspond to imaging-related information. The reaction force varies based on the imaging state, providing continuous tactile feedback to the user about camera status without causing erroneous operations or shake.
2Ease of operation
If reaction force is generated during operation, then tactile feedback is provided, but device complexity increases
Solution Approach 1:
The operation unit serves multiple functions: it detects user input operations and simultaneously generates reaction forces for tactile feedback. This multi-functionality reduces the need for separate notification mechanisms, thereby limiting the increase in device complexity while providing effective tactile feedback.
