Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle manufacturing faces challenges in achieving even and parallel margins between a grille and headlights due to uneven build tolerances, making manual adjustment labor-intensive and costly, with potential damage to decorative parts during the process.
Innovation Solution
Incorporating resilient structures, such as springs or cantilever beams, that exert equal and opposite forces to center the grille within the grille opening, ensuring equilibrium and even margins without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of the grille is performed after vehicle assembly, then the margin between grille and headlights can be equalized, but labor cost and time increase significantly
Solution Approach 1:
The resilient structures are pre-installed on the grille during initial assembly, positioned to automatically exert centering forces. This preliminary setup eliminates the need for later manual adjustment, resolving the contradiction by achieving precise margin equality without sacrificing assembly productivity.
Solution Approach 2:
The resilient structures provide self-centering capability through automatic force exertion against the vehicle structure. The system self-adjusts the grille position to achieve equal margins without requiring external manual intervention, thereby maintaining high productivity while ensuring manufacturing precision.
2Manufacturing precision
If manual adjustment of the grille is performed, then the desired aesthetic appearance can be achieved, but the risk of damage to decorative parts increases
Solution Approach 1:
The resilient structures enable the grille to self-center through controlled elastic forces, eliminating manual handling and adjustment operations. This self-service mechanism achieves precise centering accuracy while completely avoiding the damage risk associated with manual intervention on decorative parts.
Solution Approach 2:
The resilient structures act as protective cushioning elements that absorb adjustment forces through elastic deformation. By providing a compliant, controlled force mechanism before any potential damage can occur, the system achieves accurate centering while protecting the decorative grille from damage.
3Manufacturing precision
If the grille is adjusted manually at the end of the assembly line, then margin equality can be achieved, but the process becomes labor-intensive and expensive
Solution Approach 1:
The resilient structures create a self-adjusting system that automatically achieves margin uniformity through elastic force equilibrium. This eliminates the need for complex manual adjustment procedures, reducing both labor requirements and process complexity while maintaining high manufacturing precision.
Solution Approach 2:
The invention replaces the manual mechanical adjustment system with an elastic force-based self-centering mechanism. This substitution eliminates the need for operators, tools, and complex adjustment procedures, thereby reducing device complexity and labor costs while achieving the desired margin uniformity.

AI summary
A component positioning device including at least one resilient structure that centers the component. For example, a spring that acts between a grille and a grille opening to center the grille within a grille opening. The spring generating a reaction force sufficient to self-adjust the grille within the grille opening wherein opposing springs are deployed on either side of the grill with the springs exerting a force on and moving the grill until the force exerted by the opposing springs reaches equilibrium.
