Solution Overview

Problem

Users of multimedia electronic devices in vehicles face difficulties in operating various functions due to the complexity and narrow spacing of buttons, leading to malfunctions and inconvenience.

Innovation Solution

A gesture device with an input module, gesture processing unit, and control unit that acquires images, extracts gestures, and changes the locked state mode to an idle state mode based on recognized gestures, allowing users to perform functions through intuitive gestures rather than button operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If various buttons are installed in the exterior of the multimedia electronic device, then the device can perform various functions, but the user finds it inconvenient to operate and may cause malfunction due to wrong button selection

Engineering Contradiction:

ImprovefunctionalityVSAvoidoperation convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical button-pressing system with an optical gesture recognition system. The input module captures images of the user's hand gestures, and the gesture processing unit analyzes these images to determine intended commands. This substitution eliminates the need for physical buttons while maintaining diverse functionality, thereby improving ease of operation without sacrificing adaptability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a virtual representation of button functions through gesture recognition. Instead of requiring physical buttons, the system captures visual information of hand gestures and maps them to corresponding device functions. This copying approach allows multiple functions to be accessed through spatially separated gesture zones, solving the contradiction between functionality and operational convenience.

Inventive Principle:

Principle #26Copying

2Volume of moving object

If the multimedia electronic device is made small-sized, then the device becomes more portable, but the gap between buttons becomes narrow causing malfunction due to wrong button selection

Engineering Contradiction:

Improvedevice sizeVSAvoidmalfunction occurrence

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent replaces the mechanical button system with an optical gesture recognition system that is not constrained by physical space. The input module and gesture processing unit can distinguish between different gestures even in a compact device, eliminating the risk of wrong button selection while maintaining small device dimensions. This substitution allows the device to remain portable while improving reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If the user presses buttons one by one to perform functions, then the device can execute commands, but the operation process becomes very inconvenient

Engineering Contradiction:

Improvefunction executionVSAvoidoperation convenience

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the sequential mechanical button-pressing operation with parallel gesture-based command input. Multiple functions can be accessed through different gesture types captured simultaneously by the input module, eliminating the need for sequential button pressing. This substitution improves both productivity and operation convenience by allowing intuitive, direct control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Speed

If gesture control is implemented without locked state mode, then the device responds to gestures quickly, but malfunction occurs when gestures are taken in locked state mode

Engineering Contradiction:

Improveresponse speedVSAvoidmalfunction prevention

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent implements a locked state mode that is activated before gesture recognition begins. This preliminary state prevents any gesture input from being processed, thereby eliminating the risk of malfunction. When the locked state is deactivated, the system quickly responds to gestures. This preliminary action resolves the contradiction by ensuring reliability is maintained while preserving fast response speed when needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The locked state mode serves as a preliminary anti-action that blocks gesture processing before it can cause malfunction. By establishing this protective state in advance, the system prevents erroneous gesture interpretation while maintaining the capability for quick response when the locked state is properly deactivated. This approach ensures reliability without permanently sacrificing response speed.

Inventive Principle:

Principle #9Preliminary anti-action
