Vehicle Touch Screen Stabilizing Member for Hand Anchoring

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Large touch screen displays in vehicles pose challenges due to unintended motion caused by turbulence or rough roads, leading to relative motion between the operator's hand and the screen, resulting in undesired control inputs, as traditional hand rests are inadequate for stabilizing hands across the entire screen surface.

Innovation Solution

A touch screen display assembly featuring a bezel with an integrated stabilizing member that allows operators to anchor their hands at various positions around the periphery, using materials with higher friction coefficients and contours to prevent hand movement relative to the screen, such as ribs, raised surfaces, or recessed finger anchors, ensuring stable interaction even in turbulent environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional hand rest is provided adjacent the bottom side of the display screen, then hand stabilization is improved for small screens, but hand stabilization deteriorates for large screens where operators need to reach remote portions

Engineering Contradiction:

Improvehand stabilizationVSAvoidcoverage across screen surface

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The stabilizing member is divided into multiple segments or contact points distributed around the periphery of the display screen. Each segment can independently contact the operator's hand at different positions, allowing the operator to stabilize their hand at various locations around the screen rather than being limited to a single hand rest position.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stabilizing member extends around the periphery of the display screen in a distributed manner, transitioning from a single-point stabilization (traditional hand rest) to multi-point stabilization across different spatial dimensions. This allows hand anchoring at multiple positions around the screen's perimeter.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the display screen is made relatively large to provide comprehensive control interface, then control capability is improved, but hand stabilization deteriorates due to increased distance from hand rest to remote portions

Engineering Contradiction:

Improvedisplay screen areaVSAvoidhand stabilization

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The stabilizing member is segmented into multiple contact points distributed around the periphery of the large display screen. This segmentation allows operators to stabilize their hands at various positions close to different sections of the large screen, eliminating the need to reach distant remote portions and maintaining hand stabilization across the entire screen surface.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If unanticipated motion of the vehicle occurs, then operational context is improved for mobile applications, but control precision deteriorates due to unintended relative motion between operator's finger and touch sensitive screen

Engineering Contradiction:

Improvemobile application capabilityVSAvoidcontrol input accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The stabilizing member provides preliminary hand stabilization before vehicle motion occurs. By anchoring the operator's hand to the stabilizing member that is rigidly connected to the display assembly, the system creates a stable reference frame that counteracts the effects of vehicle motion, preventing unintended relative motion between the operator's finger and the touch sensitive screen.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The stabilizing member converts the potential harm of vehicle motion into a benefit by providing a stable anchoring point. The rigid connection between the stabilizing member and the display assembly ensures that any vehicle-induced motion is transferred uniformly, maintaining the relative position between the operator's hand and the touch screen, thereby preserving control input accuracy despite external disturbances.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A touch screen display assembly including, but not limited to, a touch sensitive screen, a bezel at least partly framing the touch sensitive screen, and a stabilizing member connected to the bezel and disposed proximate the touch sensitive screen. The stabilizing member is configured to stabilize a hand of an operator at multiple positions around a periphery of the touch sensitive screen when the operator interacts with the touch sensitive screen.
