Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible fabric structures, such as tents, have complex and prone-to-misplacement frames that are difficult to assemble, disassemble, and pack efficiently, particularly for large-scale applications.
Innovation Solution
A modular shelter system with self-resetting joint locks and a quick release foot mechanism, allowing for automatic locking and unlocking of joints during setup and teardown, and enabling rapid deployment and disassembly, along with a sliding locking frame and lock-out bar mechanism for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional separate frame pieces are used, then the structure can be assembled, but the frames become misplaced and are complicated to assemble, disassemble and pack
Solution Approach 1:
The patent combines multiple separate frame pieces into an integrated frame assembly with interconnected components. The frame pieces are merged through coordinated locking mechanisms and guiding features, transforming the complex task of assembling multiple independent pieces into a simpler single-unit assembly process.
Solution Approach 2:
The frame assembly incorporates self-aligning features and automatic locking mechanisms that guide components into correct positions during assembly. The design enables the frame to self-assemble through inherent mechanical guidance, reducing the need for complex manual alignment procedures.
2Productivity
If multiple separate frame pieces are used, then the structure can be formed, but they are complicated to pack for shipment
Solution Approach 1:
The frame assembly is designed to collapse into a compact nested configuration where smaller frame components fit within larger ones. This nesting arrangement significantly reduces the packed volume compared to storing multiple separate frame pieces independently, improving packaging efficiency for shipment.
3Productivity
If manual locking mechanisms are used, then joints can be secured, but they require manual intervention and are time-consuming
Solution Approach 1:
The joint locking mechanism is designed to automatically engage and secure joints without requiring manual intervention. As frame components are positioned during assembly, the locking mechanism self-activates through the natural movement and positioning of the components, rapidly securing joints without time-consuming manual operations.
4Reliability
If simple locking mechanisms are used, then assembly is fast, but the structure may not be secure in high winds
Solution Approach 1:
The locking mechanism incorporates a lock-out bar that provides enhanced security specifically at the joint locations where it is most critical. This localized reinforcement of the locking function ensures joint security in high winds without requiring complex mechanisms throughout the entire frame structure.

Implementation Method 1
when the locking pin is received in the pin-receiving slot the first and second frame elements are locked in the open position
Implementation Method 2
first biasing means for biasing the sliding locking frame towards the first end of the second frame element
Implementation Method 3
second biasing means for biasing said lock-out bar away from said sliding locking frame to an upward position
Implementation Method 4
first and second frame elements pivotally attached for relative rotation about a first axis of rotation

AI summary
A modular tent frame system comprises a number of folding frame elements which permit the shelter to be rapidly deployed. The folding elements incorporate joints with self-resetting lock mechanisms. During set up they automatically lock the joints into place and once unlocked they reset to automatically lock the joints into place on the next setup.
