Solution Overview

Problem

In audio mixers, it is challenging for users to operate controls when they are away from the main operation controller, and providing multiple operation controllers for each display increases complexity and size.

Innovation Solution

A parameter setting apparatus with a single mode operation controller that adjusts send levels or other parameters, using a processor to control displays and select buses, reducing the number of operation controllers needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple operation controllers are provided for each display, then each user can operate independently, but the number of operation controllers increases and device complexity increases

Engineering Contradiction:

Improveuser operabilityVSAvoidnumber of operation controllers

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The operation controller is designed to perform multiple functions by switching between a first adjustment mode for adjusting a send level of a selected bus and a second adjustment mode for adjusting a parameter other than the send level. This allows a single operation controller to serve multiple purposes, eliminating the need for separate controllers for different functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The operation controller dynamically switches between different adjustment modes based on user input. The mode operation controller receives designation of either the first adjustment mode or the second adjustment mode, and the processing controller accordingly changes the function of the operation controller, allowing it to adapt its behavior to different operational needs.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If a single operation controller is used for multiple functions, then the number of controllers is reduced, but the controller must handle multiple parameters including send level and other parameters

Engineering Contradiction:

Improvenumber of operation controllersVSAvoidparameter adjustment capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of the operation controller by switching between modes. In the first adjustment mode, the operation controller adjusts the send level parameter, while in the second adjustment mode, it adjusts other parameters. This parameter switching allows one controller to manage multiple different parameters effectively.

Inventive Principle:

Principle #35Parameter changes

AI summary

A parameter setting apparatus includes a first display device, a first operation controller, a mode operation controller configured to receive either designation of a first adjustment mode for adjusting a send level or a second adjustment mode for adjusting a first parameter other than the send level, and a processing controller. The controller includes a processor. The processor controls the first display device to display a bus selection screen on the display device, selects a bus based on an operation on the displayed selection screen, causes the first operation controller to adjust a send level of the selected bus upon the mode operation controller receiving the designation of the first adjustment mode, and causes the first operation controller to adjust the first parameter upon the mode operation controller receiving the designation of the second adjustment mode.
