Vehicular Door Panel Sliding Mounting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular door mounting methods require separate components and are inefficient for both assembly and disassembly, as they necessitate screws and are time-consuming and labor-intensive.
Innovation Solution
A vehicular door design featuring inner and outer panels with projecting stoppers that allow for relative sliding in a lateral direction, eliminating the need for additional mounting components by using first and second inner and outer side stoppers to securely attach and detach the panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw grommets and tapping screws are used to fix the door outer panel to the door inner panel, then the mounting strength is improved, but the device complexity increases due to requiring separate mounting members
Solution Approach 1:
The patent merges the mounting function directly into the panel structures themselves by forming protrusions on one panel and corresponding recesses on the other panel. This eliminates the need for separate mounting members like screw grommets and tapping screws, thereby reducing device complexity while maintaining mounting strength through the integrated structural connection.
2Strength
If screw grommets and tapping screws are used to fix the door outer panel to the door inner panel, then the mounting strength is improved, but the ease of operation deteriorates due to troublesome separation requiring much time and power
Solution Approach 1:
The patent segments the connection mechanism into separable protrusion and recess components that can be easily engaged and disengaged. The protrusions on one panel fit into recesses on the other panel, allowing for simple sliding-based assembly and disassembly operations. This segmentation enables easy separation without requiring tools or excessive force, directly improving ease of operation while maintaining adequate mounting strength during use.
3Strength
If screw grommets and tapping screws are used to fix the door outer panel to the door inner panel, then the mounting strength is improved, but the productivity deteriorates due to time-consuming assembly and disassembly operations
Solution Approach 1:
The patent incorporates mounting protrusions and recesses directly into the panel structures during their initial formation, rather than requiring separate mounting steps. This preliminary integration of mounting features into the panel manufacturing process eliminates the need for separate assembly operations involving screw grommets and tapping screws, significantly improving productivity by reducing both assembly and disassembly time while maintaining mounting strength.

AI summary
A vehicular door includes an inner panel and an outer panel that is mounted on a vehicular exterior side of the inner panel such that they are mounted to and separated from each other by sliding. The outer panel is mounted to the inner panel while the first outer side stopper and the first inner side stopper being fit to each other and the second outer side stopper and the second inner side stopper being fit to each other. In the relative sliding of the inner panel and the outer panel in the lateral direction, the first outer side stopper, the second inner side stopper, the second outer side stopper, and the first inner side stopper are arranged such that the first outer side stopper is not contacted with the second inner side stopper or the second outer side stopper is not contacted with the first inner side stopper.
