Portable Structure Joint With Pole-Integrated Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable structures, such as tents and umbrellas, face challenges in terms of portability, ease of erection, strength, and affordability, particularly in adverse weather conditions where complex locking mechanisms complicate the process.
Innovation Solution
A joint design for portable structures that incorporates a pivotable body with a support pole acting as part of the latching mechanism, featuring a resilient member for secure engagement and automatic retraction/extension, reducing the number of parts and steps required for erection and collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex locking mechanisms with multiple parts are used to maintain support poles in the erected position, then the strength and reliability of the structure is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The support pole is merged with the latching mechanism by integrating the retention arrangement directly onto the support pole itself. The support pole includes a retention protrusion that engages with a retention recess in the body, combining the structural support function and the latching function into a single integrated component, thereby reducing part count while maintaining structural strength
Solution Approach 2:
The support pole serves multiple functions: it provides structural support for the portable structure, acts as a latching member through its retention protrusion, and serves as a grip surface for the user. This multi-functionality eliminates the need for separate latching components while ensuring reliable structure maintenance
2Reliability
If complex locking mechanisms with multiple parts are used to maintain support poles in the erected position, then the strength and reliability of the structure is improved, but the ease of operation deteriorates

Solution Approach 2:
The latching mechanism is designed to automatically engage when the support pole is inserted into the body. The retention protrusion on the support pole automatically engages with the retention recess without requiring manual manipulation of separate latching components, allowing the structure to latch itself during the erection process
3Reliability
If multiple parts and steps are required for the latching mechanism, then the reliability of the structure is improved, but the productivity and speed of erection deteriorate

The support pole includes a retention protrusion that engages with a retention recess in the body, combining the structural support function and the latching function into a single integrated component, thereby reducing part count while maintaining structural strength

4Ease of operation
If the support pole is exposed to environmental conditions, then the ease of operation is improved, but the durability and strength deteriorate
Solution Approach 1:
The support pole is nested within the body of the joint when in the retracted position, with only the necessary portion exposed for operation. The retention protrusion engages within a retention recess in the body, allowing the support pole to be partially housed and protected from environmental conditions while maintaining user accessibility

AI summary
A joint for a portable structure for proving temporary protection for at least one person from environmental conditions, the joint comprising: a body having a first section and a second section configured to be pivotable relative to each other about a pivot axis between a collapsed position and an erected position; a first support pole and a second support pole pivotable relative to the first support pole, wherein the first pole is connected to the first section and the second pole is connected to the second section; and a latching mechanism configured to releasably secure the first section to the second section in the erected position, wherein the latching mechanism comprises: a retention arrangement located on the second section; and the first support pole; and wherein the first support pole is axially moveable relative to the first section between a retracted position and an extended position, and wherein in the extended position the first support pole is configured to extend within the second section of the body to engage with the retention arrangement and achieve latching.
