Fender Panel Mounting Structure With Detachable Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle fender panel mounting structures face challenges in easily detaching the fender panel without removing the corner window glass, suppressing vibration and noise from protrusions, and maintaining component integrity during repeated replacements, often requiring additional components that degrade the outer appearance and increase complexity.
Innovation Solution
A vehicle fender panel mounting structure featuring a triangular fixed window with a clip and slit mechanism, where the flange of the fender panel's protrusion is detachably engaged with the clip on the fixed window's opening edge, allowing for easy detachment and reattachment without additional members, and incorporating reinforcing beads to prevent vibration and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fender panel is detachably mounted using existing structures, then attachment/detachment performance is improved, but additional components are required that degrade outer appearance and increase complexity
Solution Approach 1:
The invention merges the fixed window and fender panel mounting functions into a single integrated clip structure. The clip is mounted on the fixed window and simultaneously engages with both the fixed window opening edge and the fender panel protrusion, eliminating the need for separate mounting components and achieving a clean appearance without additional parts.
Solution Approach 2:
The clip serves multiple functions: it secures the fixed window to the opening edge, provides a detachment mechanism for the fender panel, and acts as a structural support element. This multi-functional design reduces the overall component count while maintaining attachment/detachment performance.
2Object-affected harmful factors
If the fender panel protrusion is securely fixed to suppress vibration, then vibration and noise are reduced, but the clip may break during repeated replacements
Solution Approach 1:
The engagement portion of the protrusion is designed with elastic deformability, allowing it to flex during attachment and detachment operations. This dynamic characteristic absorbs stress during repeated replacements, preventing clip breakage while maintaining secure fixation for vibration suppression when properly engaged.
Solution Approach 2:
The elastic deformable engagement portion acts as a cushioning element that anticipates and absorbs mechanical stress during attachment/detachment cycles. This pre-designed flexibility protects the clip from breakage by reducing peak stresses during repeated operations.
3Strength
If the fender panel is fixed using additional members or foamed materials, then secure fixing and vibration suppression are achieved, but outer appearance is degraded and manufacturing complexity increases
Solution Approach 1:
The invention extracts and eliminates the need for additional members, foamed materials, and complex mounting structures by integrating all fixing functions into the single clip mechanism. This removal of extraneous components maintains clean outer appearance while achieving secure fixing through the clip's engagement design.
4Ease of operation
If the flange extends along the inner surface of the fixed window, then easy positioning and secure engagement are achieved, but the clip structure becomes more complex
Solution Approach 1:
The clip structure is segmented into distinct functional portions: the engagement portion that interfaces with the protrusion's flange for positioning, and the mounting portion that secures the clip to the fixed window. This segmentation allows the flange to extend along the inner surface for accurate positioning while keeping each clip component's individual complexity manageable.
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
This configuration enables easy and secure fixing of the fender panel without breaking the clip, even after multiple replacements, improves work efficiency, and suppresses vibration and noise, while maintaining an improved outer appearance by eliminating the need for additional components and foamed materials.
Implementation Method 1
The clip member includes an elastic arm portion projecting laterally outward of the vehicle body to press an edge of the fender panel laterally outward
Implementation Method 2
incorporating reinforcing beads to prevent vibration and noise

AI summary
A fender panel mounting structure for a vehicle is configured so that a fender panel can be removed without detaching the corner glass of a non-opening window. The fender panel mounting structure has the triangular non-opening window provided between a front pillar and an outside panel. A protrusion covering the upper frame member of the front pillar is formed at the upper edge of the fender panel covering the outer surface of the outside panel. A flange protruding to the inner surface side of the non-opening window from a side edge of the protrusion, the side edge facing the non-opening window, is provided on the protrusion. A clip having a slit extending in the front-rear direction of the vehicle is provided at the opening edge of the non-opening window at a position corresponding to the flange. The flange is engaged in a releasable manner with the slit.
