Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same amount of tactile stimulation is output regardless of position information, then the device is simple to operate, but the tactile stimulation cannot be adjusted according to the target position
Solution Approach 1:
The patent applies local quality by assigning different stimulation amounts to different tactile stimulation units based on their positions. The control device calculates position information for each unit and determines appropriate stimulation amounts individually, allowing the system to adapt tactile feedback to specific target positions while maintaining a relatively simple overall control structure.
2Measurement precision
If waveform analysis is used to confirm tactile presentation effects, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical approach of waveform analysis with a computational approach. The control device calculates position information and determines stimulation amounts through arithmetic operations on coordinate data, eliminating the need for complex waveform analysis while maintaining measurement precision and improving ease of operation.
