Solution Overview

Problem

Existing vehicle cooling devices have a cooling gap between the inner and outer housings that requires an oversized installation gap, leading to unwanted fluid flow and reduced cooling capacity, increasing costs, weight, and space requirements.

Innovation Solution

A clamping device is arranged around the outer housing to introduce a deformation force, reducing the cooling gap by deforming the outer housing, thereby minimizing the installation gap and eliminating unwanted fluid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a cooling gap is provided between the inner housing and outer housing to allow for installation, then the cooling device can be assembled, but unwanted cooling fluid flows beyond the channel walls reducing cooling capacity

Engineering Contradiction:
Improveinstallation capabilityVSAvoidcooling capacity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The clamping device is installed before final assembly to pre-compress the cooling gap, eliminating unwanted fluid flow paths before the cooling device becomes operational. This preliminary action ensures that the cooling fluid remains confined to the intended channels while still allowing for subsequent installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The clamping device acts as an intermediary component between the inner and outer housings, applying controlled compression to reduce the cooling gap. This intermediary mechanism allows the system to achieve both installation feasibility and cooling efficiency without requiring a complete redesign of the housing structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the cooling gap is reduced to eliminate unwanted fluid flow, then cooling capacity is improved, but installation becomes more difficult

Engineering Contradiction:
Improvecooling capacityVSAvoidinstallation difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The clamping device introduces a dynamic element to the otherwise static housing structure. By allowing the cooling gap to be compressed from a larger initial state to a reduced final state, the system transitions from an easily installable but inefficient configuration to an efficiently cooled but difficult-to-install configuration, with the clamping device mediating this transition.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The clamping device changes the physical parameter of the cooling gap size from a larger installation-friendly dimension to a smaller performance-optimized dimension. This parameter change is achieved through mechanical compression, allowing the system to optimize cooling capacity without permanently sacrificing installation ease.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the size of the cooling device is increased to eliminate unwanted flow, then cooling capacity is maintained, but cost and weight increase

Engineering Contradiction:
Improvecooling capacityVSAvoiddevice weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

Instead of increasing the overall size of the cooling device to eliminate unwanted flow, the invention extracts and addresses the specific problem area - the cooling gap between housings. By applying localized compression only where needed, the system maintains cooling capacity without adding unnecessary weight or volume to the entire device.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The clamping device applies localized compression to the cooling gap region rather than uniformly increasing the size of the entire cooling device. This local quality approach ensures that cooling capacity is maintained by eliminating unwanted flow paths only at the critical interface between housings, without adding unnecessary weight or volume elsewhere in the system.

Inventive Principle:
Principle #3Local quality

AI summary

A cooling device for a vehicle, having an inner housing with an inner cooling wall, and an outer housing which surrounds the inner housing, is spaced apart via a cooling gap and has an outer cooling wall. A cooling volume for passage of a cooling fluid is formed between the inner cooling wall and the outer cooling wall. The inner cooling wall and/or the outer cooling wall furthermore have channel walls for dividing the cooling volume and guiding the cooling fluid. At least one clamping device is arranged around the circumference of a circumferential wall of the outer housing for introducing a deformation force into the outer housing in order to reduce the cooling gap by deforming the outer housing.
