Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a fixed frequency band gain mode audio equalizer is used, then the device complexity is reduced, but the adaptability to user preferences deteriorates

Engineering Contradiction:
Improveequalizer adjustment complexityVSAvoiduser preference matching
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system automatically performs iterative selection and evaluation of equalizer curves based on user feedback, eliminating the need for manual adjustment by users. The audio device itself conducts the optimization process by presenting curve pairs, receiving user preferences, and automatically converging to the optimal equalizer settings through multiple iterations.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If a customizable frequency band gain mode audio equalizer is used, then the adaptability to user preferences is improved, but the device complexity increases

Engineering Contradiction:
Improveuser preference matchingVSAvoidequalizer adjustment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system introduces an intermediary automated selection process that mediates between the user's simple preference indication and the complex equalizer parameter space. Instead of directly exposing users to complex frequency band adjustments, the system acts as an intermediary that translates simple user feedback into precise equalizer curve selections through iterative optimization.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The equalizer adjustment process is segmented into multiple iterative steps, where each step presents only two candidate curves to the user for selection. This segmentation breaks down the complex task of adjusting multiple frequency bands into a series of simple binary choices, reducing the cognitive load on users while maintaining precision in the final result.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If iterative selection with group evolutionary strategy is used, then the manufacturing precision of equalizer parameters is improved, but the loss of time increases

Engineering Contradiction:
Improveequalizer parameter accuracyVSAvoidparameter setting time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system employs periodic iterative action where equalizer curves are selected and evaluated in repeated cycles. Each iteration refines the parameter accuracy further, and the process continues for a predetermined number of iterations or until convergence is achieved. This periodic refinement balances the need for high precision with acceptable time consumption by establishing a clear termination criterion.

Inventive Principle:
Principle #19Periodic action

AI summary

This application discloses an equalizer parameter setting method, an audio system, a device, and a readable storage medium. A computing device receives an initial equalizer population; and iteratively selects a first equalizer curve and a second equalizer curve from the initial equalizer population. An audio device selects, based on user preference data, the first equalizer curve or the second equalizer curve as a target equalizer curve. The computing device determines an iterative equalizer population based on the target equalizer curve to acquire an iterative target equalizer curve. After determining a number of iterations reaches a preset value, the computing device determines the final iterative target equalizer curve, and causes the audio device to set the corresponding equalizer parameters based on the final iterative target equalizer curve. This application iteratively selects based on the initial equalizer population, and utilizes a group evolution strategy to achieve a reduction in the search space range, improve convergence speed, and enhance the accuracy of matching between final set equalizer parameters and user preference data.
