Operating Unit Load Profile Adjustment for Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating apparatuses struggle to provide a suitable tactile feel when the operating member does not achieve sufficient moving speed at a predetermined push position, leading to inadequate load variation and feedback.
Innovation Solution
The operating apparatus includes a load application unit that adjusts load characteristics based on the moving speed of the operating unit after reaching a predetermined position. This adjustment extends the first period of load decrease when the moving speed is less than a predetermined speed, ensuring sufficient load variation and tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the operating member moves slowly when reaching the predetermined position, then the moving speed is insufficient, but extending the first period of load decrease can provide sufficient tactile feedback
Solution Approach 1:
The patent dynamically adjusts the load characteristics based on the actual moving speed of the operating unit. When the moving speed is insufficient, the control unit extends the first period of load decrease, making the system adaptive to varying operational conditions and ensuring reliable tactile feedback regardless of speed variations
Solution Approach 2:
The patent changes the temporal parameter (duration of first period) of the load characteristics based on the detected moving speed. By extending the first period when speed is low, the system maintains effective tactile feedback through parameter adjustment rather than requiring constant high speed operation
2Reliability
If the load is sharply decreased to provide tactile feel, then the tactile feedback is enhanced, but the moving speed may become insufficient to achieve proper feedback timing
Solution Approach 1:
The control unit continuously monitors the moving speed of the operating unit and uses this feedback to adjust the load characteristics. This closed-loop control ensures that the tactile feedback is provided at the appropriate moment by extending the first period when speed is low, maintaining the relationship between speed and feedback timing
3Reliability
If the first period is extended for slow moving speeds, then sufficient load variation is achieved, but the control complexity increases
Solution Approach 1:
The control unit automatically detects the moving speed and self-adjusts the load characteristics without requiring external intervention or complex control algorithms. The system serves itself by monitoring its own operational state and making appropriate adjustments to the first period duration, keeping the control complexity manageable

AI summary
An operating apparatus includes an operating unit capable of a movement operation, a load application unit configured to apply a load to the movement operation of the operating unit based on predetermined load characteristics, and an adjustment unit configured to adjust the load characteristics based on a moving speed of the operating unit after the operating unit reaches a predetermined position. The load characteristics include a first period in which the load is decreased after the operating unit reaches a predetermined position and a second period in which the load is increased after the first period. The adjustment unit adjusts the load characteristics of the first period based on the moving speed in the first period, wherein, when the moving speed in the first period is less than a predetermined speed, the adjustment unit adjusts the load characteristics of the first period so as to extend the first period.
