Solution Overview

Problem

Existing sensor arrangements on commercial vehicles, such as trucks, are exposed to environmental and external influences, offering no protection and being aerodynamically disadvantageous, which complicates installation and maintenance.

Innovation Solution

Integrating sensor devices into a pre-assembled cladding structure at the upper end region of the windshield within the driver's cab, providing protection and maintaining the driver's field of vision while simplifying installation and reducing aerodynamic impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If sensors are mounted on the roof of the commercial vehicle, then the sensors are easily accessible and simple to install, but the sensors are exposed to environmental influences and external effects without protection

Engineering Contradiction:
Improveease of sensor installationVSAvoidexposure to environmental and external influences
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The sensor device is integrated into the cladding structure, which is then installed within the driver's cab. This nesting approach protects the sensor while maintaining ease of installation through the pre-assembled unit.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cladding structure serves as an intermediary element that provides protection for the sensor device. Instead of mounting the sensor directly on the roof, the cladding structure acts as a protective intermediary housing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If sensors are mounted on the roof of the commercial vehicle, then installation is simplified, but the aerodynamics of the vehicle are adversely affected

Engineering Contradiction:
Improveease of sensor installationVSAvoidaerodynamic drag
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The sensor device is nested within the cladding structure that is installed inside the driver's cab, eliminating protruding roof mounts and their associated aerodynamic penalties while keeping installation straightforward.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of repair

If sensors are mounted on the roof of the commercial vehicle, then the sensors are easily accessible for maintenance, but the sensors offer no protection against vandalism

Engineering Contradiction:
Improveease of sensor maintenanceVSAvoidvandalism risk
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The sensor device is nested within the protective cladding structure installed in the driver's cab, providing security against vandalism while maintaining accessibility for authorized maintenance through the integrated design.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cladding structure provides localized protection specifically for the sensor device within the driver's cab, creating a secure environment while allowing controlled access for maintenance purposes.

Inventive Principle:
Principle #3Local quality

4Ease of operation

If sensors are mounted on the roof of the commercial vehicle, then the sensors are externally accessible, but the driver's field of vision may be impaired

Engineering Contradiction:
Improvesensor accessibilityVSAvoiddriver's field of vision obstruction
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of mounting sensors on the external roof surface, the sensor device is inverted to the internal cladding structure within the driver's cab, eliminating visual obstruction while maintaining operational accessibility.

Inventive Principle:
Principle #13The other way round (Inversion)
