Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical instruments require multiple controllers to vary multiple parameters simultaneously, which is cumbersome and time-consuming to set up.
Innovation Solution
A parameter control device with a master knob that collectively controls multiple parameter values using a value acquiring unit and parameter output unit, based on a setting information and correspondence relation between an indicating value and coordinates in a defined area, allowing simultaneous control of multiple parameters with a single controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple controllers are used to vary multiple parameters simultaneously, then parameter control capability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
A single operation element is designed to control multiple parameters simultaneously through a mapping relationship with coordinate axes. Each coordinate axis corresponds to a different parameter, allowing one controller to perform the function of multiple controllers while maintaining full parameter control capability
Solution Approach 2:
The operation element's control space is extended from one dimension to multiple dimensions by mapping it to a coordinate system with multiple axes. Each axis represents a parameter that can be independently adjusted, enabling multi-parameter control through a single element by moving in different directional dimensions
2Adaptability or versatility
If multiple controllers are used to vary multiple parameters simultaneously, then parameter control capability is improved, but ease of operation worsens
Solution Approach 1:
The single operation element serves multiple functions by controlling multiple parameters at once. Users can adjust multiple parameters through one operation instead of coordinating multiple controllers, significantly simplifying the operation process while maintaining comprehensive parameter control
Solution Approach 2:
Multiple control functions that would normally require separate controllers are merged into a single operation element. The mapping mechanism combines multiple parameter adjustments into one unified control action, reducing operational complexity
3Adaptability or versatility
If multiple controllers are used to vary multiple parameters simultaneously, then parameter control capability is improved, but setup time increases
Solution Approach 1:
By designing a single operation element with multi-parameter control capability from the outset, the system eliminates the need to set up and configure multiple separate controllers. The mapping relationship is established once, allowing immediate use without time-consuming setup procedures

AI summary
A parameter control device according to an embodiment includes a value acquiring unit and a parameter output unit. The value acquiring unit acquires an indicating value of a first operation element. The parameter output unit outputs a plurality of parameter values corresponding to the acquired indicating value, based on setting information and a correspondence relation between the indicating value and a coordinate in an area defined by a plurality of coordinate axes. The setting information is for setting a relation between a plurality of parameter values and a coordinate. The plurality of parameter values being for controlling a state of content.
