Solution Overview

Problem

Conventional rooftop tents are bulky, difficult to assemble, and lack a secure fixing mechanism, making them inconvenient to install and prone to theft.

Innovation Solution

A rooftop tent fixing device with clamp bodies, fixing brackets, and a fastening rod system that allows easy installation and secure attachment to a vehicle's frame, featuring shock-absorbing members and a locking mechanism to prevent theft.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fixing means such as bolts or clamps are used to attach the rooftop tent to the frame, then the tent can be securely fixed, but the fixing work becomes inconvenient due to narrow space between the frame and tent, and there is a risk of theft

Engineering Contradiction:
Improvefixing strengthVSAvoidinstallation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a fixing device as an intermediary component between the rooftop tent and the vehicle frame. This fixing device includes a clamp body that clamps the frame and a fixing bracket that connects to the tent bottom, creating a mediator structure that simplifies the fixing process while maintaining security and preventing theft through integrated locking mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If conventional tents are used for leisure activities, then they provide adequate sleeping capacity, but they are bulky, difficult to assemble and dismantle, and complex in structure causing frequent joint failures

Engineering Contradiction:
Improvesleeping capacityVSAvoidstructure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The rooftop tent is divided into separate modular components: a tent body, a fixing frame with clamp bodies, and fixing brackets. This segmentation allows each component to be optimized independently, reducing overall complexity while maintaining sleeping capacity and improving ease of assembly and disassembly

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If conventional tents are stored in vehicles for transport, then they can be taken to camping sites, but they occupy significant space making it difficult to store other preparations

Engineering Contradiction:
ImproveportabilityVSAvoidstorage space requirement
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The tent design incorporates dynamic elements including a convertible roof structure that can change from horizontal to inclined positions, and collapsible side walls that can be folded or removed. This dynamic configuration allows the tent to be compacted to minimal volume for vehicle storage while expanding to provide adequate sleeping space at the camping site

Inventive Principle:
Principle #15Dynamics
