Vehicle Front Fascia Sag Prevention via Removable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing front fascias for vehicles, typically made of plastic, are difficult to manipulate and prone to sagging or damage due to their size and material before installation, which poses challenges in handling and installation.
Innovation Solution
A front fascia design featuring an upper and lower fascia member, first and second connection members, and a temporary connection member that is removable before installation, providing support and preventing sagging or damage by being configured for easy removal and made of recyclable plastic materials like polypropylene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the front fascia is made of plastic material to achieve decorative function and cost-effectiveness, then the manufacturing cost is reduced and aesthetic appearance is improved, but the fascia becomes difficult to manipulate and prone to sagging or damage during handling and installation
Solution Approach 1:
The front fascia is divided into multiple segments including upper and lower fascia members, grille members, and connection members. This segmentation allows each component to be handled separately, reducing the difficulty of manipulation and installation while maintaining the overall decorative function of the complete assembly
Solution Approach 2:
Temporary connection members are introduced as intermediary elements to support the fascia members during handling and installation. These temporary supports prevent sagging and damage by providing structural assistance during the critical installation phase, then are removed to allow final assembly
2Ease of manufacture
If the front fascia is made of plastic material to achieve decorative function and cost-effectiveness, then the manufacturing cost is reduced and aesthetic appearance is improved, but the fascia becomes prone to sagging or damage during handling and installation
Solution Approach 1:
Temporary connection members are installed beforehand to provide structural support and prevent sagging or damage during handling and installation. These members act as protective elements that cushion the plastic fascia components from stress and deformation until they are securely mounted to the vehicle
Solution Approach 2:
By dividing the fascia into multiple smaller members connected by connection members, the structural load is distributed across multiple elements rather than concentrating stress on single large plastic components, reducing the risk of damage
3Reliability
If temporary connection members are added to support the fascia during handling and installation, then sagging and damage are prevented, but the device complexity increases
Solution Approach 1:
The temporary connection members are designed as disposable or single-use components that are installed temporarily during handling and installation, then removed. This approach adds minimal permanent complexity to the final assembly while providing necessary support during the critical installation phase
Solution Approach 2:
The temporary connection members are extracted or removed after serving their protective function during installation. This ensures they do not remain as permanent complexity in the final assembly, maintaining structural integrity only when needed during handling and installation

AI summary
A front fascia for a vehicle includes an upper fascia member, a lower fascia member, a connection member, and a temporary connection member. The connection member extends between the upper fascia member and the lower fascia member. The temporary connection member extends between the upper fascia member and the lower fascia member. The temporary connection member is configured to be removable prior to installation of the front fascia to the vehicle.
