Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible, elongate structure modules face challenges when used in modular beam structures due to tensional, compressive, and torsional forces, particularly in applications where a lying beam structure is required, as existing solutions are not directly applicable.
Innovation Solution
A collapsible, elongate support structure module with a dead center mechanism at the hinge connection and a releasable locking device, allowing for adjustable angles between side elements and enabling secure engagement of adjacent edges, which forms a beam structure capable of changing direction and resisting loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If collapsible structure modules are used in modular beam structures, then the structure can be assembled and disassembled, but the module cannot adequately resist tensional, compressive, and torsional forces
Solution Approach 1:
The side elements are divided into multiple parts connected by hinge connections, allowing the structure to be segmented for easy assembly and disassembly while maintaining structural integrity when locked
Solution Approach 2:
The hinge connections enable dynamic adjustment of side elements to different angles, allowing the module to adapt to various beam configurations while the locking device provides static stability when loaded
2Volume of moving object
If the side elements are made collapsible for easy storage and transport, then the module volume is reduced, but the structure becomes less stable under load
Solution Approach 1:
The side elements can dynamically transition between collapsed and unfolded states through hinge connections, providing volume reduction for storage while maintaining stability when locked in the unfolded position
Solution Approach 2:
The locking device automatically engages to stabilize the side elements when they are unfolded and loaded, providing self-stabilization without requiring additional support structures
3Stability of the object's composition
If a releasable locking device is added to interlock adjacent edges of side elements, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The locking device is designed to automatically engage and lock adjacent edges of side elements when they are positioned correctly, providing self-stabilization without requiring complex control mechanisms or additional components

AI summary
A modular beam structure consisting of one or more collapsible, lockable and interconnectable support structure modules, and any transition module to change longitudinal direction of the structure. In addition, it is possible to attach onto one or more support structure modules a collapsible platform and/or wall or fence. The structure is at an upstream end or start end attachable, via a module end element, onto an attachment device, e.g. a wall or attachment block, via a support frame which is fixedly attached to the attachment device.
