Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch type operating elements require multiple operating elements and a display for parameter switching, resulting in a complex configuration and user-unfriendliness.
Innovation Solution
A parameter controlling apparatus with an operation input portion that detects different operation manners for value change and type switching, allowing for parameter value adjustment and type selection using a single touch type operating element without additional displays or elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating elements and a display are used for parameter switching, then parameter switching functionality is achieved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The touch type operating element is designed to perform multiple functions: it can change parameter values through sliding operations and switch parameter types through pressing operations. This multi-functionality eliminates the need for separate operating elements and displays, resolving the contradiction between versatility and device complexity
Solution Approach 2:
The invention merges the functions of multiple operating elements and a display into a single touch type operating element. By combining these components, the system achieves parameter switching functionality while reducing configuration complexity and improving ease of operation
2Adaptability or versatility
If multiple operating elements and a display are used for parameter switching, then parameter switching functionality is achieved, but ease of operation deteriorates
Solution Approach 1:
The touch type operating element serves as a universal control interface that handles both parameter value adjustment and parameter type switching through different operation modes. This eliminates the need for users to learn and operate multiple different elements, significantly improving ease of operation while maintaining full parameter switching functionality
3Device complexity
If a single touch type operating element is used for both value change and type switching, then device complexity is reduced and ease of operation is improved, but detection precision requirements increase
Solution Approach 1:
The detection portion uses different detection methods for different operation types: it detects sliding operations for parameter value changes and pressing operations for parameter type switching. By applying localized detection strategies to different operational contexts, the system maintains simple configuration while effectively distinguishing between different operation manners

AI summary
A parameter controlling apparatus has a CPU 201 and operation input portion 302, 303 and 305 which include an operating area 303 whose operated position can be detected, and accept input operation. The CPU 201 detects whether the operation input portion is operated in the first manner or the second manner in accordance with the accepted input operation, and detects the content of the input operation of the operating area 303. In a case where the first manner has been detected, the CPU 201 also changes a value of a target parameter in accordance with the content of the input operation of the operating area 303. In a case where the second manner has been detected, the CPU 201 also switches a type of a target parameter in accordance with the content of the input operation of the operating area 303.
