Solution Overview

Problem

Conventional camping tents are not compatible with electric vehicles and lack the ability to receive conditioned air, making it difficult to maintain an optimum temperature during high or low temperatures without an external electric supply.

Innovation Solution

A detachable electric vehicle camping tent device that attaches to a vehicle's side window, utilizing a connecting duct to transfer conditioned air from the vehicle, ensuring an optimum temperature without external power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If conventional camping tents are used, then portability and affordability are improved, but the ability to maintain optimum temperature during high or low temperatures deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidtemperature control
Core Design Contradiction:
Length of moving objectVSTemperature

Solution Approach 1:

The patent introduces an intermediary system consisting of a connector portion and connecting duct that mediates between the electric vehicle's air conditioning system and the tent's interior space. This intermediary structure enables temperature control by channeling conditioned air from the vehicle into the tent, resolving the contradiction between maintaining portability and achieving temperature control capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If tents are made compatible with electric vehicles by adding connector portions and connecting ducts, then temperature control capability is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature controlVSAvoidstructure complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the tent system into distinct functional modules: the main tent housing, the connector portion, and the connecting duct. This modular segmentation allows the temperature control components to be added as separate units rather than integrating complexity throughout the entire tent structure, thereby improving temperature control while managing device complexity through organized modularity.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If conditioned air is supplied to the tent without external power, then ease of operation is improved, but the need for vehicle proximity constraint increases

Engineering Contradiction:
Improveease of operationVSAvoidlocation flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements self-service by utilizing the electric vehicle's existing air conditioning system to provide conditioned air to the tent without requiring any additional external power sources or independent cooling equipment. The tent system serves itself by drawing conditioned air directly from the vehicle through the connecting duct, which simplifies operation but inherently requires proximity to the vehicle for the system to function.

Inventive Principle:
Principle #25Self-service

AI summary

An electric vehicle camping tent device that is designed to detachably attach to a side window of an electric vehicle for receiving conditioned air from the vehicle, thereby maintaining a cool (or warm) temperature inside the tent device. The tent device comprises a tent housing made of conventional tent device material and includes an electric vehicle connector portion attached to the housing. The connector portion is connected to the housing using a connecting duct that forms a passage for conditioned air from the electric vehicle to the housing. The connector portion is designed as a pop-in window attachment with window sealant positioned on the outer surface of the connector portion. The tent device is collapsible and can be folded for easy transportation inside a vehicle. The housing forms an enclosed space for enabling users to camp inside the tent device.
