Solution Overview

Problem

The installation of a center high-mounted stop lamp (CHMSL) within a vehicle spoiler complicates servicing, often requiring the entire spoiler to be replaced, leading to high servicing costs.

Innovation Solution

A spoiler structure with an upper panel, lower panel, inner panel, and detachable bracket system, allowing for easy access and maintenance of the CHMSL without replacing the entire spoiler.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the CHMSL is mounted within the vehicle spoiler, then the aerodynamic performance and styling are improved, but the servicing complexity and cost increase

Engineering Contradiction:
Improveaerodynamic performanceVSAvoidservicing complexity
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The spoiler is divided into multiple segments including a first spoiler segment, a second spoiler segment, and a third spoiler segment. The CHMSL is specifically mounted in the third spoiler segment, which can be independently removed. This segmentation allows servicing of the CHMSL without removing the entire spoiler, thus resolving the contradiction between maintaining aerodynamic performance and reducing servicing complexity.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the entire spoiler is replaced to service the CHMSL, then the CHMSL can be accessed, but the servicing cost increases

Engineering Contradiction:
ImproveCHMSL accessibilityVSAvoidservicing cost
Core Design Contradiction:
Ease of repairVSLoss of substance

Solution Approach 1:

The spoiler structure is segmented into multiple independent parts, with the third spoiler segment containing the CHMSL being separable from the first and second spoiler segments. This allows only the necessary third segment to be removed for CHMSL servicing, avoiding the need to replace the entire expensive spoiler assembly, thus reducing servicing costs while maintaining accessibility.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If the spoiler is designed as a single integrated structure, then the manufacturing is simpler, but the assembly quality and serviceability decrease

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidassembly quality
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The spoiler is designed with multiple segments (first, second, and third spoiler segments) that can be manufactured separately and then assembled together using coupling mechanisms. This segmentation approach maintains manufacturing simplicity for each individual segment while improving overall assembly quality and serviceability, as each segment can be precisely manufactured and independently serviced.

Inventive Principle:
Principle #1Segmentation

AI summary

A spoiler structure for a vehicle is provided. The spoiler structure includes an upper panel that includes an extended segment that is configured to be mounted on a rear portion of the vehicle. The spoiler structure further includes a lower panel that is coupled to an end segment of the upper panel. The spoiler structure further includes an inner panel that is disposed along the extended segment of the upper panel and a first portion of the lower panel such that a space is formed between the inner panel and the lower panel that is configured to include at least one sensor unit. The spoiler structure further includes a bracket that is detachably attached to a first surface of the inner panel using a plurality of fasteners.
