Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays for point-of-sale advertising are inefficient in terms of transportation and deployment, as they often require manual assembly and lack mechanisms for maintaining an erect state without additional support.
Innovation Solution
Self-erectable pop-up displays with a tubular shroud structure that includes internal support structures and elastic members, allowing for easy folding and transportation, and automatic deployment to an erect state using lines of weakness and elastic biasing forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional displays are used for point-of-sale advertising, then they can provide advertising information, but they require manual assembly and additional support structures, increasing device complexity and manual effort
Solution Approach 1:
The display structure is divided into multiple segments connected by hinge joints, allowing each segment to be independently folded and positioned. The stop members are also segmented with translating components that can move independently within slots, enabling simplified assembly while maintaining structural integrity when deployed
Solution Approach 2:
The elastic members provide automatic biasing forces that cause the display structure to self-erect and maintain its deployed position without requiring manual assembly or additional support structures. The stop members with translating elements automatically engage with the hinge joints to maintain segment spacing, eliminating the need for complex assembly procedures
2Stability of the object's composition
If conventional displays are used, then they can display information, but they lack mechanisms for maintaining an erect state, requiring additional support structures
Solution Approach 1:
The elastic members function as counterbalancing elements that provide continuous biasing forces to counteract gravitational and external forces acting on the display structure. This allows the display to maintain its erect state without additional support structures, as the elastic members internally compensate for destabilizing forces
Solution Approach 2:
The stop members with translating elements automatically engage with the hinge joints to maintain proper segment spacing and structural configuration. The translating stop elements move within slots to accommodate structural changes while maintaining stable engagement, enabling the display to self-maintain its erect state without external support
3Adaptability or versatility
If displays are made foldable for easy transportation, then they can be easily transported and stored, but they require complex hinge joints and stop members to maintain structural integrity
Solution Approach 1:
The display structure is divided into multiple foldable segments connected by hinge joints, enabling compact folding for transportation and storage. The stop members are segmented with translating components that move within slots, allowing the structure to fold while maintaining structural integrity when deployed
Solution Approach 2:
The stop members incorporate translating elements that can dynamically move within slots along the hinge joints. This dynamic capability allows the stop members to accommodate structural changes during folding and deployment, maintaining structural integrity without requiring complex fixed mechanisms

AI summary
A pop-up display apparatus includes a shroud having first and second sheets disposed in opposition to one another, the first and second sheets being connected to one another at a first side by a first joint and at a second side by a second joint. A stop member is disposed between the first and second sheets between the first and second joints and is connected to the first and second joints at a first height of the shroud. The stop member includes first and second stop elements arranged for translational movement in opposite directions relative to one another between a first and a second position. An elastic member, separate from the stop member, is connected to the first and second joints at a second height, the elastic member and being configured to bias the first joint toward the second joint. The first position of the stop member corresponds to a stowed state of the pop-up display and a substantially flat shroud profile and the second position of the stop member corresponds to a deployed state of the pop-up display and a convex shroud profile.
