Solution Overview

Problem

Existing volume level settings on electronic devices do not adapt to the diverse preferences of users, with some finding volumes too loud or too soft regardless of adjustments.

Innovation Solution

The electronic device adjusts its volume curve by altering the number of levels, the volume differences between levels, and the range of volumes available, based on user habits, environment, and connected devices, allowing for more personalized volume adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed volume levels are set before delivery, then device complexity is reduced and ease of manufacture is improved, but adaptability to different user preferences deteriorates

Engineering Contradiction:
Improveadaptability to user preferencesVSAvoidvolume adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic volume level adjustment by allowing the system to modify the number of volume levels (N to M) and the volume differences between levels based on user behavior patterns. The volume curve is no longer fixed but adapts dynamically according to detected user operations and environmental conditions, resolving the contradiction between fixed simplicity and adaptive versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes key parameters of the volume curve including the number of levels, volume differences between adjacent levels, and the overall volume range. By adjusting these parameters based on user habits and environmental context, the system achieves adaptability to different user preferences while maintaining a relatively simple underlying adjustment mechanism.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If fixed volume levels are set before delivery, then ease of operation is improved for simple use, but the need for manual adjustment increases when user preferences differ

Engineering Contradiction:
Improvevolume adjustment convenienceVSAvoidtime for manual adjustment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically adjusts volume levels by detecting user operations and environmental conditions, eliminating the need for manual intervention. The device monitors user behavior patterns (such as frequent adjustments between certain levels) and autonomously modifies the volume curve to better suit user preferences, thereby reducing the time users would otherwise spend on manual adjustments while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates feedback mechanisms by monitoring user volume adjustment operations and environmental conditions. This feedback is used to automatically refine the volume curve, creating a closed-loop system that continuously improves ease of operation by reducing the need for manual adjustments over time.

Inventive Principle:
Principle #23Feedback

3Object-affected harmful factors

If volume levels are adjusted to meet individual preferences, then user comfort is improved, but device complexity increases

Engineering Contradiction:
Improveuser discomfort from volumeVSAvoidadaptive volume system
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies local quality by customizing the volume curve specifically for each user's preferences and environmental context rather than using a uniform adjustment approach. The system detects user-specific patterns (such as sensitivity to certain volume ranges) and adjusts the volume differences between levels locally to eliminate discomfort, thereby achieving personalized comfort without requiring complete system redesign.

Inventive Principle:
Principle #3Local quality

AI summary

A volume adjustment method and an electronic device are provided. The electronic device includes N volume levels, the N volume levels include a first level and a second level, the first level corresponds to first volume, the second level corresponds to second volume, and a difference between the first volume and the second volume is a first difference. The electronic device adjusts the N volume levels to M volume levels when a first condition is satisfied, where the M volume levels include a third level and a fourth level, the third level and the first level are a same level, the fourth level and the second level are a same level, the third level corresponds to third volume, the fourth level corresponds to fourth volume, and a difference between the third volume and the fourth volume is a second difference. The M volume levels satisfy at least one of the following: M is not equal to N; the third volume is not equal to the first volume; the fourth volume is not equal to the second volume; or the second difference is not equal to the first difference. In this manner, volume of the electronic device can meet requirements of different users.
