Vehicle Garnish Frame Adjustment for Flush Exterior Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exterior decoration devices for vehicles, such as garnishes and logos, face challenges in achieving a uniform appearance due to level differences between components assembled using mounting clips, which are difficult to manage, especially in the design trend of smooth surfaces for electric vehicles.
Innovation Solution
A dispersion management type exterior decoration device that employs a level difference adjustment bolt with a dispersion adjustment structure and an excessive torque cut-off mechanism, allowing for the adjustment of fastening length to absorb dimension dispersion and prevent surface level differences, ensuring a smooth external appearance by matching the garnish or logo with the outer panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a garnish is directly assembled with an outer panel by a mounting clip, then the garnish can be fixed to the panel, but a surface level difference is formed between the formed section and the straight surface of the garnish
Solution Approach 1:
The patent introduces an intermediate structure (mounting clip with adjustable fastening length) between the garnish and the outer panel. This intermediary component absorbs dimensional dispersion and allows adjustment to eliminate surface level differences, thereby resolving the contradiction between reliable fixing and surface uniformity.
Solution Approach 2:
The patent changes the parameter of fastening length of the mounting clip to adjust the position of the garnish relative to the outer panel. By varying this parameter, the surface level difference can be compensated, achieving both reliable fixation and uniform surface appearance.
2Adaptability or versatility
If the garnish is assembled with a dual panel structure including an outer panel and an inner panel, then the garnish can be disposed in a space between the panels, but it is difficult to manage a gap level difference between the garnish and the outer panel
Solution Approach 1:
The mounting clip is designed to automatically compensate for dimensional variations through its adjustable fastening length. The clip itself performs the function of managing gap level differences without requiring additional adjustment mechanisms, achieving both assembly flexibility and manufacturing precision.
3Strength
If the exterior decoration device is fastened to the outer panel or the inner panel by the mounting clip, then the garnish can be securely attached, but it is structurally difficult to meet the design trend of inhibiting components manufactured separately from protruding
Solution Approach 1:
The mounting clip is designed with dynamic adjustability in its fastening length, allowing it to adapt to different dimensional variations. This dynamic characteristic enables the clip to maintain secure attachment while accommodating the garnish at the correct position to achieve surface smoothness, resolving the contradiction between attachment strength and surface smoothness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces surface and gap level differences, prevents non-uniform appearances, and withstands excessive torque, providing a smooth design suitable for future electric vehicles by aligning the garnish or logo with the outer panel without protrusions.
Implementation Method 1
including a reaction force hook protruding inclinedly from a rim portion thereof and configured to be elastically deformed
Implementation Method 2
configured to adjust both a surface level difference of the garnish exposure member and a hook level difference of the reaction force hook by inducing a rotation of the dispersion adjustment structure and changing a protrusion length from the garnish frame
