Vehicle Door Mounting Assembly for Tight Interior Panel Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door assemblies in motor vehicles face challenges in achieving a small gap pattern between the interior panel component and the door skin, which affects the visual quality and requires significant effort to manufacture.
Innovation Solution
A door assembly design where a carrier component with mounting elements is used to mount both the interior panel component and the carrier itself on the door skin, optimizing the attachment and minimizing gaps through the use of mounting elements with head portions and latching mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carrier component is used to mount functional components on the door skin, then the functional components can be securely attached, but the gap pattern between the interior panel component and door skin increases
Solution Approach 1:
The patent combines the mounting function for both the carrier component and the interior panel component into a single mounting element. The mounting element has a head portion that receives the interior panel component and a shank portion that attaches to the door skin, eliminating the need for separate mounting operations and reducing cumulative gaps.
Solution Approach 2:
The mounting element is designed to serve multiple functions: it acts as both the mounting component for the carrier component on the door skin and the mounting component for the interior panel component on the carrier component. This multi-functionality reduces the number of parts and minimizes gap accumulation.
2Reliability
If multiple mounting elements are arranged on the carrier component, then the interior panel component can be securely fixed, but the device complexity increases
Solution Approach 1:
The same mounting element design is used for both mounting the carrier component to the door skin and mounting the interior panel component to the carrier component. This standardized approach reduces device complexity while maintaining secure fixation through consistent mounting mechanisms.
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 design enhances the visual quality of the door assembly by reducing the gap pattern and simplifies the manufacturing process by allowing the interior panel component to be attached directly to the carrier component, which is itself securely fastened to the door skin.
Implementation Method 1
the receptacle is formed to provide an enlarged passage opening by virtue of elastically flexible side walls during the passage of the head portion and, after the head portion has passed the receptacle, to return to an original state with a smaller passage opening

AI summary
A door assembly and an assembly method for a door assembly with a door skin, a support component and an interior trim component, the support component is fastened to the door skin by at least one mounting component. The at least one mounting component is also used for mounting the interior trim component since a head section of the mounting component projects from the support component and the interior trim component is mounted on the head section.
