Foldable Display Stand With Internal Elastic Ties And Spacers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing point-of-sale advertising displays, such as 'TOTEM' devices, require complex and expensive mechanisms for volume deployment and are difficult to fold back due to the use of elastic members under tension, making manufacturing and folding challenging.
Innovation Solution
A display stand with automatic deployment using a sheath of semi-rigid material featuring internal elastic links and spacers, where the spacers allow tensioning of the elastic links to open the display and retain them in place, eliminating the need for pre-tensioned elastic members during manufacturing and enabling easy folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If elastic members are placed under tension during manufacturing, then automatic deployment is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The elastic members are installed in their relaxed state during manufacturing, and the sheath is pre-folded along longitudinal lines. The actual tensioning action is deferred to a later stage when the sheath is unfolded, eliminating the need for complex tensioning mechanisms during assembly while still achieving automatic deployment functionality
Solution Approach 2:
The sheath is divided into multiple foldable sections along longitudinal lines, allowing it to be collapsed into a compact flat state for transport and then automatically deployed when the elastic members are tensioned during the unfolding process
2Extent of automation
If elastic members are placed under tension during manufacturing, then automatic deployment is achieved, but manufacturing cost increases
Solution Approach 1:
The sheath is pre-folded and elastic members are installed in their relaxed state during manufacturing, avoiding the need for expensive tensioning mechanisms. The tensioning action is performed later during the unfolding process, simplifying the manufacturing process and reducing costs
3Extent of automation
If elastic members under tension are used, then automatic deployment is achieved, but folding the support becomes difficult
Solution Approach 1:
The elastic members dynamically adjust their tension state: during folding operations, the sheath can be compressed which relaxes the elastic members, allowing easy folding. During deployment, the sheath is unfolded which automatically tensions the elastic members, providing the restoring force for automatic deployment
4Strength
If the sheath is made rigid for volume use, then structural integrity is maintained, but folding becomes difficult
Solution Approach 1:
The sheath is segmented into multiple foldable sections along longitudinal lines, allowing it to be collapsed into a compact flat state for transport while maintaining structural integrity when deployed. The segmented structure enables both rigidity in use and flexibility during folding
Solution Approach 2:
The sheath utilizes a flexible semi-rigid material that can maintain its shape and structural integrity when deployed in volume, yet can be easily folded along pre-defined longitudinal lines when collapsed, providing both strength and foldability
