Solution Overview

Problem

Conventional portable rooms attached to collapsible shelters face instability issues due to wind and other elements, primarily because the rigid frame of the shelters does not provide adequate stability, and the assembly process is cumbersome.

Innovation Solution

A multi-point attachment system is introduced, featuring flexible straps and adjustable attachment points on the shelter's frame, allowing for secure fastening of structures like flags, banners, and sidewalls both internally and externally, and a flexible strap connecting the portable room's roof to the shelter's peak links for enhanced wind resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rigid frame is used for the portable shelter, then structural strength is improved, but stability against wind and elements deteriorates

Engineering Contradiction:

Improvestructural strengthVSAvoidstability against wind

Core Design Contradiction:

StrengthVSStability of the object's composition

Solution Approach 1:

The patent applies the dynamics principle by replacing the rigid frame with a flexible frame that can dynamically adapt to external forces. The flexible frame members are capable of bending and deforming under wind load, allowing the structure to move with the force rather than resist it statically, thereby improving stability against wind while maintaining structural integrity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the physical parameter of the frame from rigid to flexible. This parameter change allows the frame to exhibit different mechanical properties under different conditions - maintaining strength while gaining flexibility to respond to environmental forces, thus resolving the contradiction between structural strength and wind stability

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If conventional attachment methods are used, then assembly is simple, but attachment security and stability deteriorate

Engineering Contradiction:

Improveassembly simplicityVSAvoidattachment security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies segmentation by dividing the attachment system into multiple discrete attachment points distributed along the frame rather than using a single attachment method. This allows the structure to be secured at multiple locations, improving overall attachment security while maintaining ease of assembly through standardized connection elements at each segment

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the portable room is attached to the shelter frame, then integration is improved, but stability in wind conditions deteriorates

Engineering Contradiction:

ImproveintegrationVSAvoidwind stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies the flexible shells principle by using flexible frame members that can bend and deform under wind load. This flexibility allows the integrated portable room structure to absorb wind forces through controlled deformation rather than rigid resistance, improving wind stability while maintaining good integration with the shelter frame

Inventive Principle:

Principle #30Flexible shells and thin films
