Solution Overview

Problem

In vehicles for urban use, the compact dimensions restrict the installation of conventional heating, ventilation, and air conditioning systems, making it difficult to maintain comfort due to space constraints.

Innovation Solution

A thermal conditioning installation with a heat treatment module in the front compartment and an air distribution module in the passenger compartment, featuring exterior and interior air inlets with adjustable flaps and internal partitions to optimize space usage, allowing for compact design and improved airflow management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a conventional heating, ventilation and/or air conditioning installation is installed in the passenger compartment, then thermal comfort is ensured, but the available space in the passenger compartment is reduced

Engineering Contradiction:
Improvethermal comfortVSAvoidpassenger compartment space
Core Design Contradiction:
TemperatureVSArea of stationary object

Solution Approach 1:

The thermal conditioning installation is divided into two separate modules: a heat treatment module positioned in the front compartment and an air distribution module positioned in the passenger compartment. This segmentation allows the system to maintain thermal comfort functions while reducing the space occupation in the passenger compartment, as the bulk of the system (heat treatment module) is relocated to the front compartment where space is more readily available.

Inventive Principle:
Principle #1Segmentation

2Length of moving object

If the vehicle dimensions are reduced for urban use, then urban maneuverability is improved, but the installation of thermal conditioning systems becomes difficult

Engineering Contradiction:
Improvevehicle dimensionsVSAvoidsystem installation
Core Design Contradiction:
Length of moving objectVSEase of manufacture

Solution Approach 1:

By segmenting the thermal conditioning installation into two modules positioned in different compartments, the system adapts to the reduced overall vehicle dimensions suitable for urban use. The air distribution module in the passenger compartment can be compact while the heat treatment module in the front compartment handles the bulk of thermal processing, enabling installation in space-constrained urban vehicles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system utilizes the longitudinal dimension of the vehicle by distributing components across different zones (front compartment vs. passenger compartment) rather than concentrating everything in the transverse plane of the passenger compartment. This dimensional redistribution allows the system to accommodate reduced vehicle dimensions while maintaining installation feasibility.

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

3Area of stationary object

If the dashboard size is reduced to maintain comfort, then passenger space is increased, but the thermal conditioning installation cannot be positioned

Engineering Contradiction:
Improvepassenger compartment spaceVSAvoidinstallation positioning
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The thermal conditioning installation is segmented into two independently positionable modules: the heat treatment module in the front compartment and the air distribution module in the passenger compartment. This segmentation provides installation flexibility, allowing the air distribution module to be positioned in the passenger compartment regardless of dashboard size, while the heat treatment module is positioned in the front compartment where dashboard reductions do not impact available space.

Inventive Principle:
Principle #1Segmentation
