Dynamic Control Interface for Audio Parameter Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to distinguish between parameter settings controlled individually and those controlled interlockedly using multiple controls or a common control in audio devices like digital mixers, making it hard to understand and manage parameter settings effectively.
Innovation Solution
A method that allows users to switch between a first mode for individual parameter control and a second mode for interlocked control using a one-knob mode, where individual elements are displayed as operable or non-operable based on the mode, ensuring easy recognition and management of parameter settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple individual controls are provided for each parameter, then each parameter can be controlled independently with high precision, but the device complexity increases and it becomes difficult for users to recognize whether parameters are controlled individually or interlockedly
Solution Approach 1:
The control interface dynamically changes its state based on the selected mode. In individual control mode, multiple individual controls are displayed and enabled. In interlocked control mode, the interface transitions to show only a common control. This dynamic reconfiguration resolves the contradiction by adapting the interface complexity to the current operational requirement.
Solution Approach 2:
The patent uses visual state changes (analogous to color changes) to indicate the operational mode. Controls transition between enabled and disabled states, and the display updates to reflect whether individual or interlocked control is active. This visual feedback mechanism helps users immediately recognize the current control mode without confusion.
2Ease of operation
If one common control is used to control multiple parameters in an interlocked manner, then the ease of operation improves for coordinated parameter adjustment, but it becomes difficult for users to recognize that the parameters are being controlled interlockedly rather than individually
Solution Approach 1:
The display provides continuous feedback about the current operational mode. When in interlocked control mode, the display clearly indicates this state and shows which parameters are being controlled together. This feedback mechanism prevents loss of information about the control mode, allowing users to understand whether they are adjusting parameters individually or as an interlocked group.
Solution Approach 2:
The patent adds a temporal dimension to the control interface by switching between different display configurations. The interface transforms from showing multiple individual controls to showing a single common control based on the selected mode. This dimensional transformation in the interface presentation preserves control mode information while maintaining ease of operation.
3Adaptability or versatility
If both individual controls and common control are combined, then both individual parameter adjustment and coordinated control are enabled, but the device complexity increases and user understanding becomes more difficult
Solution Approach 1:
The control interface dynamically switches between individual control mode and interlocked control mode based on user selection. When in individual control mode, only individual controls are active and displayed. When in interlocked control mode, only the common control is active and displayed. This dynamic separation maintains versatility while preserving user understanding by ensuring that at any given time, the interface presents a clear, unambiguous control paradigm.

AI summary
A first mode (one-knob off mode) and a second mode (one-knob on mode) are provided as modes for setting parameters. In the first mode, individual elements corresponding to respective parameters of a parameter set are displayed in an operable state, allowing setting of individual parameters. In the second mode, the individual elements are displayed in a non-operable state, and one-element is displayed in an operable state, and a plurality of parameters of the parameter set are controlled by operating the one-element. At the time of switching from the first mode to the second mode, the parameter set is initialized.
