Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional cover accessories for electronic devices hinder the viewing of displayed information and consume excessive battery life due to the need for separate circuits and light sources, particularly when a flashlight is positioned at the rear, leading to visibility issues and diminished battery efficiency.

Innovation Solution

A cover accessory featuring a front cover with a fluorescent material and a light reflection layer, which transfers and enhances the display light without requiring a separate circuit or light source, allowing for improved visibility and marketability while reducing battery consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a separate circuit or light source is used in the cover accessory to transfer information, then information transfer capability is improved, but battery consumption increases

Engineering Contradiction:

Improveinformation transfer capabilityVSAvoidbattery consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The cover accessory utilizes the display light from the electronic device itself to transfer information, rather than requiring a separate power source. The fluorescent material and light reflection layer work passively with the existing display light, allowing the system to serve itself without additional energy input.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The fluorescent material and light reflection layer act as intermediaries to transfer information from the display to the user's eye. These materials mediate the interaction between the display light and the user, enabling information transfer without requiring active electronic components or additional power sources in the cover.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Illumination intensity

If a flash light source is positioned at the rear surface of the electronic device, then information visibility is improved, but the position becomes skewed to one side and visibility deteriorates when viewed from the front

Engineering Contradiction:

Improveinformation visibilityVSAvoidlight source position alignment

Core Design Contradiction:

Illumination intensityVSShape

Solution Approach 1:

Instead of using a light source at the rear surface that shines forward, the invention inverts the approach by using the display light itself and reflecting it through fluorescent materials in the cover. This reverses the traditional illumination direction and eliminates the need for rear-mounted light sources.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The fluorescent material in the cover changes the color or wavelength of the display light, enhancing visibility and adding design elements. This color transformation allows the cover to actively participate in light manipulation without requiring additional light sources.

Inventive Principle:

Principle #32Color changes

3Productivity

If a light reflection layer is formed in the central area of the front cover, then light transfer efficiency is improved, but the edge area visibility may be reduced

Engineering Contradiction:

Improvelight transfer efficiencyVSAvoidedge area visibility

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The light reflection layer is selectively positioned in the central area of the front cover rather than uniformly across the entire surface. This localized placement optimizes light transfer efficiency for the display area while leaving the edge areas with different optical properties, balancing overall visibility and aesthetic appearance.

Inventive Principle:

Principle #3Local quality
