Solution Overview

Problem

Existing outdoor advertisement and disaster prevention systems require constant deployment of large-sized displays, which is inefficient and wasteful, as they are always visible and consume resources even when not in use.

Innovation Solution

A support type display device featuring a flexible display panel that can be rolled and unrolled as needed, utilizing shape maintaining means such as shape storage alloys or gas injection mechanisms to transition between rolled and unrolled states, allowing for efficient deployment only when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large-sized advertising board or screen is constantly deployed outdoors, then the visual transfer effect is enhanced and advertisement/disaster prevention functionality is available, but resource waste increases and energy consumption occurs even when not in use

Engineering Contradiction:
Improveadvertisement and disaster prevention functionalityVSAvoidresource waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The display panel is designed to be dynamically deployable and storable. It can be unrolled and fixed to the support when advertisement or disaster prevention is needed, and rolled up and stored when not in use. This dynamic configuration allows the system to adapt between deployed and stored states, providing functionality only when required and eliminating constant resource consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display panel is temporarily deployed for specific purposes (advertisement or disaster prevention) and then recovered by rolling it up and storing it. This approach allows the system to discard the deployed state when not needed and recover the panel for future use, thereby reducing resource waste while maintaining functionality when required.

Inventive Principle:
Principle #34Discarding and recovering

2Loss of substance

If a flexible display panel is made rollable and unrollable, then resource efficiency is improved and energy is conserved when not in use, but the device complexity increases due to shape maintaining means

Engineering Contradiction:
Improveresource efficiencyVSAvoidshape maintaining means
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The display panel is designed to be nested within itself when rolled up, forming a compact cylindrical structure. The shape maintaining means includes a support structure that provides a mounting point for the rolled panel, allowing it to be neatly stored in a compact form factor while maintaining structural integrity during storage and deployment.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The shape maintaining means is pre-configured with a support structure and fixing mechanism before deployment. When the display panel needs to be deployed, it is simply unrolled and fixed to the support, and when storage is needed, it is rolled up and fixed to the same support. This preliminary configuration of the support structure eliminates the need for complex active control mechanisms during deployment and storage operations.

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If the display panel is rapidly deployed for disaster prevention, then the response time is reduced, but the mechanical stress on the shape maintaining means increases

Engineering Contradiction:
Improvedeployment timeVSAvoidmechanical stress resistance
Core Design Contradiction:
Loss of timeVSStrength

Solution Approach 1:

The display panel and shape maintaining means are designed to work together in a dynamic deployment system. The flexible nature of the display panel allows it to be quickly unrolled and fixed to the support structure, enabling rapid deployment for disaster prevention while the support structure absorbs and distributes the mechanical stress during this quick transition.

Inventive Principle:
Principle #15Dynamics
