Field Tent Arch Frame Channel Coupling for Rapid Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medium-sized field tents for civil defense or military use require excessive time for unfolding and lack sufficient load-bearing capacity and thermal insulation for medium-long term use, with existing quick unfolding tents failing to maintain structure integrity and insulation in adverse conditions.
Innovation Solution
A field tent and mounting kit featuring arch frames with structural elements and pulling cables, along with an inner and outer sheet configuration, allowing for rapid assembly while maintaining load-bearing and insulation capabilities through a kedler-type coupling system and additional thermal insulation layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medium-sized residential tents are used for medium-long term use, then load-bearing capacity and thermal insulation are maintained, but assembly time becomes excessive (up to 45 minutes)
Solution Approach 1:
The tent structure is divided into modular components: arch frames with integrated structural elements, separable outer and inner sheets, and distinct pulling cable assemblies. This segmentation allows for rapid assembly while maintaining the structural integrity needed for medium-long term use, reducing assembly time from 45 minutes to a faster deployment without sacrificing load-bearing capacity.
Solution Approach 2:
The structural elements are pre-integrated into the arch frames during manufacturing, with channels and coupling mechanisms prepared in advance. The outer sheet is pre-formed with enlarged edge portions that fit into these channels. This preliminary preparation eliminates the need for complex field assembly operations, enabling quick deployment while ensuring the structure maintains its load-bearing capacity for extended use.
2Loss of time
If quick unfolding tents are used, then assembly time is reduced (about 10 minutes), but load-bearing capacity and thermal insulation deteriorate
Solution Approach 1:
The invention merges the quick assembly features with the structural elements needed for medium-long term durability. The arch frames combine structural support function with integrated channels for sheet attachment. The pulling cables are integrated into the arch frame structure rather than being separate temporary components. This merging allows the tent to assemble quickly like temporary structures while maintaining the load-bearing capacity and insulation properties of permanent structures.
Solution Approach 2:
The arch frames serve multiple functions simultaneously: providing structural support, guiding the outer sheet through integrated channels, and supporting the pulling cable mechanism. The structural elements are designed to perform both quick assembly operations and long-term load-bearing functions. This multi-functionality eliminates the need for separate temporary and permanent structure components, allowing quick deployment with sustained durability.
3Strength
If special tie-rods are installed to increase load-bearing features, then structural strength is improved, but device complexity and assembly time increase
Solution Approach 1:
The structural elements are nested within the arch frame structure itself. The channels with open annular sections are integrated into the arch frame, and the enlarged edge portions of the outer sheet are nested within these channels. The pulling cables are routed through and integrated with the arch frame structure. This nesting eliminates the need for external tie-rods and separate bracing components, maintaining structural strength while reducing overall complexity.
Solution Approach 2:
The arch frames are self-sufficient in providing structural support without requiring external tie-rods or additional bracing components. The integrated structural elements within the arch frames perform the load-bearing function that would otherwise require separate tie-rod assemblies. The structure serves itself, eliminating the need for complex external support systems and simplifying both assembly and maintenance.

AI summary
A quick assembly field tent (1), comprises a plurality of arch frames (10, 11, 12) each comprising at least one structural element (100) having a pair of first channels with an open annular section (150, 151) which extend along a prevailing direction of the structural element. The field tent (1) further comprises at least one outer sheet (2), comprising at least one enlarged edge portion (21) received in a channel of the pair of first channels with an open annular section (151) of the structural element. An inner sheet (3) is shaped so as to comprise a roof portion (31) and vertical side walls (32) joined to the roof portion (31), said inner sheet (3) being arranged internally to the outer sheet (2) and at least partially spaced from the outer sheet (2). The inner sheet (3) comprises a hooking portion (33) for its installation.
