Solution Overview

Problem

In van-type vehicles, drivers must exit the vehicle to retrieve items from a vehicle-mounted refrigerator, and placing a cooling box in the passenger compartment makes it difficult for passengers to access.

Innovation Solution

A vehicle design featuring a cooling box integrated into the door or seat, allowing it to be easily accessed by passengers, with the box being rotatably or slidably mounted to facilitate reachability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a vehicle-mounted refrigerator is disposed in the vehicle, then cooling functionality is provided, but passengers must exit the vehicle to retrieve items

Engineering Contradiction:
ImproveAccessibility to cooling boxVSAvoidTime to retrieve items
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The cooling box is integrated into the door structure rather than being placed on the floor or dashboard, utilizing the vertical and lateral space of the door panel. This dimensional repositioning brings the cooling box within arm's reach of seated passengers, eliminating the need to exit the vehicle while maintaining cooling functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the cooling box is mounted on the door, then passenger accessibility is improved, but the door structure becomes more complex

Engineering Contradiction:
ImproveAccessibility to cooling boxVSAvoidDoor structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The door structure is segmented into functional modules: the cooling box unit with its own mounting bracket, rotation mechanism, and sliding mechanism. This modular segmentation allows the cooling box to be independently installed and adjusted without redesigning the entire door structure, managing complexity through functional decomposition.

Inventive Principle:
Principle #1Segmentation
