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

VSEngineering 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

Engineering Contradiction:
Improvestructural strengthVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvestructural strengthVSAvoiderection ease
Core Design Contradiction:
ReliabilityVSEase of operation

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvestructural strengthVSAvoiderection speed
Core Design Contradiction:
ReliabilityVSProductivity

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

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

Inventive Principle:

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

Engineering Contradiction:
Improvegrip surface availabilityVSAvoidenvironmental exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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

Inventive Principle:
Principle #7Nested doll (Nesting)
