Solution Overview

Problem

Audio processing apparatuses, such as audio mixers, require a reduction in the number of controls to minimize size while maintaining operability and functionality.

Innovation Solution

The audio processing apparatus is designed with a unique operation panel configuration that integrates multiple controls in a compact form, utilizing a combination of angled surfaces and strategically placed display elements to reduce depth and size while enhancing user accessibility, and employs a single encoder for both screen and channel modes to minimize physical controls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the number of controls is reduced to minimize size, then the overall size of the apparatus is reduced, but the operability and functionality may be compromised

Engineering Contradiction:
Improveoverall sizeVSAvoidoperability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The encoder is designed to perform multiple functions: it can operate as a screen encoder for navigating display options and as a channel strip encoder for adjusting audio parameters. This multi-functionality allows the apparatus to maintain full operational capabilities while using fewer physical controls, directly resolving the contradiction between size reduction and operability maintenance

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The encoder's function is made dynamic through switching between screen encoder mode and channel strip encoder mode. The control panel dynamically reconfigures the encoder's purpose based on operational context, allowing a single control element to adapt to different operational requirements without sacrificing functionality or increasing size

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a single encoder is used for both screen and channel modes, then the number of physical controls is minimized, but the complexity of control assignment increases

Engineering Contradiction:
Improvenumber of physical controlsVSAvoidcontrol assignment flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary assignment of parameters to the encoder before operation. Parameters are pre-configured and assigned to specific encoder positions or modes, so that during actual use, the encoder can directly access these pre-arranged functions without requiring complex real-time configuration, thus maintaining simplicity while preserving adaptability

Inventive Principle:
Principle #10Preliminary action

3Length of stationary object

If controls are integrated in a compact form, then the depth and size are reduced, but the accessibility and visibility of controls may be affected

Engineering Contradiction:
ImprovedepthVSAvoidaccessibility
Core Design Contradiction:
Length of stationary objectVSEase of operation

Solution Approach 1:

The control panel utilizes angular surfaces and three-dimensional positioning to arrange controls. By transitioning from a flat two-dimensional layout to an angled three-dimensional configuration, the design achieves compact depth while maintaining accessible positioning and visibility of controls through strategic spatial arrangement

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
