Solution Overview

Problem

Conventional glare reduction hoods for touchscreen displays block all sides, making it difficult and cumbersome to utilize touch functions while attempting to reduce ambient light glare.

Innovation Solution

A glare reduction hood with a closure structure that is mountable on a touchscreen display, featuring a pierceable panel with an openable and predisposably closed access slit, allowing easy access and continuous glare reduction by intimately conforming around piercing objects to prevent light transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional glare reduction hood blocks all sides of the display, then glare reduction is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveglare reductionVSAvoidtouchscreen access

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The hood is divided into multiple panels, with at least one panel being pierceable to create selective access points. This segmentation allows the hood to maintain its glare-blocking function while providing localized access to the touchscreen display through the pierceable panel.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pierceable panel is positioned at a specific location on the hood to provide localized access to the touchscreen. This allows users to interact with the display through the pierceable panel while other areas of the hood continue to block ambient light effectively.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If a glare reduction hood is added to a touchscreen display, then glare reduction is improved, but device complexity increases

Engineering Contradiction:

Improveambient light blockingVSAvoidhood structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The hood utilizes a flexible pierceable panel that can be penetrated by touch input devices. This flexible panel design simplifies the overall structure compared to rigid mechanisms, while still providing effective glare reduction and touchscreen access functionality.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A glare reduction hood for a touchscreen display includes an elongated closure structure having an open mounting end and an opposite, open viewing end. The mounting end is mountable on the touchscreen display such that the hood projects outwardly from the touchscreen display. The elongated closure structure includes a pierceable panel disposed between the mounting and viewing ends and having an openable and predisposably closed access. The closure structure shields the touchscreen display, the access is pierceable by a piercing object and intimately fitable around the piercing object preventing light from passing through the access, and the touchscreen display is viewable through the viewing end and contactable via the access.
