Retractable Flexible Display for 1:1 Scale Blueprint Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper drawings in the AEC industry are cumbersome and difficult to manage, update, and view accurately due to their large size, while digital solutions either lack portability or fail to provide an ideal viewing experience at 1:1 scale.
Innovation Solution
A retractable electronic blueprint display device featuring a flexible display housed in a cylindrical structure with a core that allows partial or full extraction, enabling a 1:1 scale representation of drawings and easy updating, with control features and modular design for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If paper drawings are used to view full-size drawings, then 1:1 scale viewing is achieved, but portability and ease of management deteriorate
Solution Approach 1:
The patent uses a flexible electronic display that can be rolled up like paper but provides digital copying capabilities. The display shows drawings at 1:1 scale similar to paper, yet incorporates electronic storage and transmission functions, allowing digital copies to be easily managed while maintaining accurate scale representation for viewing.
Solution Approach 2:
The flexible display technology enables the viewing surface to change from a compact rolled state to a fully extended flat state, altering its physical parameters (area, shape) while maintaining the 1:1 scale viewing capability. This parameter change allows the device to transition between portable and viewing modes.
2Ease of manufacture
If paper drawings are used, then ease of updating is poor, but manufacturing simplicity is maintained
Solution Approach 1:
The electronic display system replaces physical paper drawings with digital copies that can be instantly updated. The flexible display shows electronic versions of drawings that can be modified and refreshed without requiring physical reproduction, significantly improving update efficiency while the device itself remains relatively simple in construction.
Solution Approach 2:
The system transitions from static paper drawings to dynamic electronic displays that can be updated in real-time. The flexible display adapts its content dynamically, allowing drawings to be changed, updated, or replaced electronically without physical manipulation of the drawing medium.
3Ease of operation
If digital displays are used for viewing, then portability improves, but viewing experience at 1:1 scale deteriorates
Solution Approach 1:
The flexible display technology fundamentally changes the physical parameters of the viewing surface by enabling it to be rolled up for portability and then fully extended to provide a large flat viewing area. When extended, it maintains the 1:1 scale viewing capability that was previously only available with paper, thus resolving the contradiction between portability and viewing scale accuracy.

AI summary
Provided is a modular display device for providing a digital representation of a blueprint. In one example, the device includes an elongated housing having an elongated opening parallel to a longitudinal axis of the housing. A core is configured to fit inside the housing in a rotatable manner. A flexible display is configured to move between one state where a majority of the flexible display is positioned inside the housing and rolled around the core and another state where a majority of the flexible display is moved out of the housing through the opening and positioned outside of the housing to form a viewing surface. A height and a width of the flexible display are sufficient to provide a 1:1 scale view of a drawing having dimensions defined by a drawing standard used in at least one of an architectural industry, an engineering industry, or a construction industry.
