Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems require multiple actuators and additional display units to control different operating parameters or variables, which increases complexity and component count, whereas the proposed system uses a single rotary actuator with magnetic fixation to control various parameters or variables on a larger screen without additional actuators or display units.
Innovation Solution
A control system with a screen and magnetically fixed rotary actuator, featuring multiple actuation areas for positioning, where sensors detect angular and rotational movements to control different parameters or variables, and magnetic attraction guides the actuator's movement between positions, eliminating the need for additional actuators and display units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple actuators and additional display units are used to control different operating parameters, then the control capability is improved, but the device complexity increases
Solution Approach 1:
A single rotary actuator is designed to perform multiple functions by being positioned at different locations on the control panel. The actuator can control different operating parameters (volume, temperature, speed, etc.) depending on its position, eliminating the need for multiple dedicated actuators and display units while maintaining full control capability
Solution Approach 2:
The patent combines multiple control functions into a single actuator unit. By merging the functionality of what would traditionally require separate actuators and display units into one multi-position actuator, the system achieves the same control capability with reduced complexity
2Device complexity
If a single rotary actuator is used to control multiple parameters, then the device complexity is reduced, but the ability to distinguish different actuation areas must be improved
Solution Approach 1:
The patent replaces complex mechanical position-detection mechanisms with magnetic field sensing. Sensors detect the angular position of the rotary actuator through magnetic field interactions, enabling precise detection of which actuation area the actuator is in without requiring complex mechanical switches or contacts
Solution Approach 2:
Magnetic fields serve as an intermediary between the rotary actuator and the sensors. The magnetic coupling allows the sensors to detect the actuator's angular position and identify its actuation area without direct mechanical contact, simplifying the detection system while improving reliability
