Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controls for medical apparatuses with numerous movable segments are cumbersome and lack intuitive operation, particularly for operating tables, due to the increased number of buttons or soft keys, and do not provide efficient control over the speed and direction of motion.
Innovation Solution
A remote control equipped with sensors to detect position and motion, emitting control signals based on the remote control's motion and the actuation of a release switch, allowing intuitive control of movable components through simple button or soft key actuation, and featuring a display for verification and adjustment of motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of buttons or soft keys is increased to control numerous movable segments, then the control capability is improved, but the ease of operation deteriorates due to cumbersome operation and difficulty in finding appropriate buttons
Solution Approach 1:
The remote control device uses a single release button that serves multiple functions: it releases the lock for any selected movable segment and enables motion control in multiple directions. The sensor detects the remote control's orientation and motion to determine the desired movement direction, eliminating the need for separate buttons for each direction and segment.
Solution Approach 2:
The system uses the remote control device itself as the input mechanism for direction control. Instead of requiring the user to press specific buttons for each direction, the sensor automatically detects the remote control's orientation and motion, allowing the remote control to serve its own purpose for both selection and direction indication.
2Measurement precision
If multiple switches are provided for each movable segment to control motion in different directions, then the control precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a sensor-based detection system. The sensor detects the remote control's orientation and motion in space, converting physical movements into control signals. This eliminates the need for multiple mechanical switches while maintaining precise directional control through spatial detection.
Solution Approach 2:
The control interface moves from a two-dimensional button matrix to three-dimensional spatial control. The sensor detects the remote control's orientation and motion in three-dimensional space, allowing directional control through spatial positioning rather than through multiple discrete buttons on a flat surface.
3Ease of operation
If intuitive operation with speed adjustment is provided, then the ease of operation is improved, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent replaces manual speed adjustment mechanisms with sensor-based detection. The sensor measures the speed and distance of the remote control's motion, automatically converting these physical parameters into appropriate control signals for the movable segments. This provides intuitive speed control without requiring separate speed adjustment buttons or dials.
Solution Approach 2:
The system incorporates feedback by using the sensor to continuously monitor the remote control's motion characteristics (speed, distance, direction) and automatically adjusting the control signals accordingly. This feedback loop enables intuitive operation where the movable segments respond naturally to the user's motion inputs without requiring manual intervention for speed and position adjustments.
