Solution Overview

Problem

Large radiator grilles on vehicles, especially SUVs, face installation challenges due to measurement deviations and material expansion issues, leading to gaps and increased logistical and cost burdens from using multiple independent grille elements.

Innovation Solution

A cover unit comprising two or more detachable cover elements connected via a tear-off tab system, allowing for simple assembly and handling, with optional features like film hinges and U-clamps to prevent twisting and premature detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a radiator grille is formed as a one-piece component, then manufacturing and handling are simplified, but installation becomes extremely difficult due to measurement deviations and material expansion

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidinstallation difficulty
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The radiator grille is divided into multiple separate grille elements that can be individually manufactured and then connected during assembly. This segmentation allows each element to be produced independently, accommodating measurement deviations and material expansion while maintaining overall structural integrity through the connecting section with tear-off tabs.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If several independent radiator grille elements are used, then installation precision is improved, but logistical investments and costs increase

Engineering Contradiction:
Improveinstallation precisionVSAvoidlogistical complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Multiple grille elements are connected together using connecting sections with tear-off tabs to form a single integrated cover unit. This merging reduces logistical complexity by treating multiple elements as one unit during manufacturing and transportation, while still allowing for precise individual installation by simply tearing off the tabs at the assembly location.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a one-piece radiator grille is used, then handling is simplified, but visible gaps form between the grille and bumper system due to measurement deviations

Engineering Contradiction:
Improvehandling simplicityVSAvoidgap formation
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The grille is segmented into multiple elements that can independently adjust to fit the bumper system contours, eliminating gaps caused by measurement deviations. Each element can be precisely positioned and secured to the bumper structure while maintaining visual continuity.

Inventive Principle:
Principle #1Segmentation

4Manufacturing precision

If multiple independent grille elements are used, then gap formation is reduced, but assembly complexity and time increase

Engineering Contradiction:
Improvegap reductionVSAvoidassembly time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

Multiple grille elements are pre-connected forming a single cover unit that reduces assembly time. The connecting sections with tear-off tabs allow for rapid disconnection and repositioning if needed, while the integrated structure ensures proper spacing and alignment that prevents gap formation during installation.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to a shielding unit, in particular a radiator grille unit (1) intended to be mounted on a bumper system situated at the front of a motor vehicle, the radiator grille unit (1) comprising at least two shielding elements, in particular grille elements (2, 3, 4). There is provision in this respect for the shielding unit to be formed in one piece, respectively two shielding elements being interconnected in a removable manner by means of a connecting section (5) which preferably comprises a tearable tongue. The shielding unit can thus be manufactured simply as a monoblock component and handled simply from a logistic point of view. The tearable tongues are torn during mounting and the various shielding elements can be mounted independently and separately in a simple and precise manner.
