Solution Overview

Problem

Conventional display apparatuses for vehicle passengers require complex operations to split the screen, are prone to remote controller misplacement, and limit the display area due to layout constraints, making it time-consuming and inefficient to utilize wasted space for landscape-oriented images.

Innovation Solution

A display apparatus with a touch-sensitive screen that detects finger movements to split the display by calculating transfer length and location shift, allowing simple screen splitting operations without the need for dedicated remote controllers or layout limitations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screen split keys or selection keys are provided on the display apparatus or remote controller, then the display screen can be split into multiple regions, but the operation becomes complex and time-consuming

Engineering Contradiction:

Improvescreen split capabilityVSAvoidoperation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display screen itself serves as the operation interface by detecting finger touch and movement directly on the screen. The system automatically detects touch start point, touch end point, and calculates transfer length to determine split position, eliminating the need for separate control keys or remote controllers.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The control functionality is extracted from physical buttons and remote controllers and integrated directly into the touch-sensitive display screen. The screen now performs both display and control functions, allowing users to operate the device by touching the screen surface directly.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If escutcheon switches or selection keys are laid out on the display apparatus, then screen splitting can be controlled, but the display area is reduced due to layout space requirements

Engineering Contradiction:

Improvescreen split controlVSAvoiddisplay area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The control interface is merged with the display surface. The same touch-sensitive screen that displays images also detects finger touches and movements for control operations. This integration eliminates the need for separate physical control elements that would occupy display area.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Control functionality is moved from a two-dimensional button layout to the entire screen surface as the interaction dimension. By utilizing the full screen area for both display and control, the system maximizes display space while maintaining control capabilities through touch gestures.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If a remote controller is used for screen splitting, then the display apparatus can be operated, but the remote controller may be misplaced or lost

Engineering Contradiction:

Improveremote control operationVSAvoidremote controller availability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The display screen performs its own control function by detecting finger touches directly on its surface. This eliminates the dependency on an external remote controller, ensuring that control functionality is always available as long as the display screen is accessible.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The display screen serves multiple functions: it displays images and simultaneously acts as the control interface for screen splitting operations. This multi-functionality integrates the control system into the display itself, removing the need for a separate remote controller.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If selection keys are displayed on the touch panel, then the interface can be updated dynamically, but the operation takes time every time switching is needed

Engineering Contradiction:

Improveinterface flexibilityVSAvoidscreen switching time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of finger touch position and movement on the screen surface. By continuously monitoring touch input and calculating transfer length in real-time, the system is ready to execute the split operation immediately when the gesture is completed, eliminating the need to display and select from multiple keys each time.

Inventive Principle:

Principle #10Preliminary action

AI summary

A touch location detection section (103) detects the location on a display screen where the operator's finger touches. A transfer length calculation section (104) calculates the transfer length La of the operator's finger from the touch start location S to the touch end location E. A transfer length judgment section (105) judges whether or not the transfer length La is greater than a reference transfer length Ls. A location shift calculation section (106) calculates the location shift δ of the operator's finger. A location shift judgment section (107) judges whether or not the location shift δ is less than a predetermined reference location shift δs. When La>Ls and δ<δs, a screen split control section (108) controls the operation of an image display section so as to split a display screen 101.
