Solution Overview

Problem

Existing mobile tents face challenges with limited compactness in transport position, complex assembly, potential mechanical failures, and inadequate stability and wind resistance, especially in large sizes.

Innovation Solution

A tent design featuring a central mast, lateral masts, and extendable support arms with scissor links that connect the masts, allowing for a compact transport position and easy setup, utilizing scissor links for stability and wind resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If telescopic sections are used for the mast, then the tent can be moved from transport position to erection position, but the reduction in volume for transport is limited and disassembly requires complex technique

Engineering Contradiction:
Improvemobility between transport and erection positionVSAvoidassembly and disassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support arms are divided into multiple scissor link segments that can be easily connected and disconnected. Each scissor link is a separate component that attaches to the mast and support arms, allowing simple assembly by connecting these modular segments without complex locking mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scissor links are extracted as separate removable components from the mast structure. This allows the support arms to be easily detached from the mast by simply removing the scissor links, eliminating the need for complex locking mechanisms and making disassembly trivial.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If telescopic sections with locking mechanisms are used, then the tent can be extended to erection position, but repair becomes difficult and costly when sections become jammed

Engineering Contradiction:
Improveextension capabilityVSAvoidaccessibility of telescopic sections
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The scissor links are segmented into separate, easily accessible components positioned along the length of the support arms. This segmentation allows any individual scissor link to be quickly accessed and replaced without disassembling the entire structure, making repair simple and cost-effective.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scissor links are designed as extractable components that can be removed from the mast and support arms without specialized tools or techniques. This extraction capability enables easy replacement of jammed or damaged links, eliminating the need for costly repairs of integrated telescopic sections.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If maximum stability and load-bearing capacity are achieved, then the tent can resist high wind forces, but weight and material cost increase

Engineering Contradiction:
Improvewind resistance and mechanical stabilityVSAvoidtent weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The scissor links are pre-positioned along the support arms at optimal locations to provide structural reinforcement where needed. This preliminary placement of reinforcement elements achieves maximum stability with minimum material, avoiding the need to over-engineer the entire structure with heavy materials throughout.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The scissor links provide localized reinforcement at critical points along the support arms and mast connections. This local quality approach strengthens the structure at specific high-stress areas rather than uniformly increasing the weight of all components, achieving high wind resistance with minimal additional weight.

Inventive Principle:
Principle #3Local quality
