Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sound control function is used to operate electronic devices, then the operation can be performed without manual control, but the user experience remains simple and limited

Engineering Contradiction:

Improvemanual controlVSAvoiduser experience

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic switching between different face images based on sound intensity levels. The system transitions from a static display to a dynamic one where the user's face image changes in real-time according to their voice volume, creating a more engaging and adaptive interaction experience

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent utilizes sound intensity as a variable parameter to control the switching between different face images. By monitoring changes in sound intensity and mapping them to specific face image selections, the system transforms a simple sound control function into a versatile interaction mechanism

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple face images are switched based on sound intensity, then user participation and immersion are enhanced, but the device complexity increases

Engineering Contradiction:

Improveuser participationVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the sound detection mechanism serve multiple functions: it not only controls the switching between different face images but also potentially triggers other interactive responses. This multi-functionality reduces the need for separate components for each function, thereby managing complexity while enhancing user participation

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements a feedback loop where the user's sound input is detected, processed, and immediately reflected in the display through face image switching. This real-time feedback creates an immersive experience without requiring complex intermediate processing steps

Inventive Principle:

Principle #23Feedback

AI summary

A data processing method and apparatus, and a readable medium and an electronic device. The method comprises: collecting a facial image of a user by means of a terminal, and taking the collected facial image as a first facial image (11); displaying the first facial image in a user display area of a terminal screen (12); where the terminal screen displays a target object, collecting a sound signal of the user, and taking the collected sound signal as a target sound signal (13); and if the sound intensity of the target sound signal is within a first intensity range, switching a display state of the target object, and switching the first facial image in the user display area to a second facial image (14), wherein the second facial image is obtained on the basis of the first facial image. In this way, the sense of participation and timeliness of a user when operating a terminal can be enhanced, and manual control of the user is not needed, thereby improving the experience of the user when using the terminal.
