Solution Overview

Problem

Existing radar mounting devices for motor vehicles, particularly those near the air guide, often compromise the aerodynamic properties of the air guide, leading to suboptimal performance.

Innovation Solution

A radar mounting device with a support structure that includes a first structural element above a second structural element, with the support passing through an opening in the air guide, utilizing a flexible sealing lip and a design that minimizes disruption to the air guide's aerodynamics, allowing for secure fixation without altering the air guide's functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a radar support is mounted near the air guide, then the radar can be positioned close to the front of the vehicle for optimal detection, but the aerodynamic properties of the air guide are compromised

Engineering Contradiction:
Improveradar detection capabilityVSAvoidaerodynamic performance
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The radar support structure is nested within the air guide assembly by passing through an opening in the air guide. The support integrates with the existing air guide structural elements, allowing the radar to be positioned near the front of the vehicle while maintaining the air guide's aerodynamic envelope.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The opening in the air guide is equipped with sealing lips at specific locations to maintain aerodynamic sealing only where necessary. The sealing lips are positioned to prevent air leakage while allowing the radar support to pass through, thus preserving aerodynamic properties in critical areas while accommodating the radar mounting.

Inventive Principle:
Principle #3Local quality

2Reliability

If the support passes through the air guide opening, then the radar can be securely mounted, but air leakage may occur compromising the cooling system efficiency

Engineering Contradiction:
Improveradar mounting stabilityVSAvoidcooling system efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Sealing lips made of flexible material are installed at the opening of the air guide to prevent air leakage. These flexible sealing elements conform to the opening geometry and create an effective seal around the radar support while allowing for thermal expansion and vibration.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing lips act as an intermediary element between the radar support and the air guide opening. They mediate the conflict between needing a secure mounting passage and maintaining aerodynamic sealing, by providing a flexible sealing interface that accommodates both requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)
