Integrated Door Grip Mounting Structure With Single Fastening Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting structures for integrated door grips and handles in vehicle door trims require multiple fixing points and complicate the installation process at customer sites, as the door grip and inside handle need to be fixed to the door panel before the door trim is mounted, making the process cumbersome and time-consuming.
Innovation Solution
A simplified mounting structure for a grip with an integrated handle, where the grip and handle are integrally formed with a bracket extending from the grip portion to the handle portion, allowing the handle to be fixed to the door panel with a single fastening point, eliminating the need for separate fixation of the grip end to the panel and allowing the door trim to be mounted independently with an integrated-type cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the inside handle case is directly fixed to the door panel and the grip base is directly fixed to the door panel at two points, then the mounting strength is improved, but the device complexity and installation difficulty increase due to requiring three fixing points and complex assembly sequence
Solution Approach 1:
The patent combines the inside handle case and grip base into a single integrated door grip assembly. The bracket extends continuously from the grip portion to the handle portion, creating one unified structure that is mounted to the door panel as a single unit. This merging eliminates the need for separate fixation of multiple components and reduces the number of fixing points required, thereby simplifying the mounting structure while maintaining strength.
2Strength
If the door grip and inside handle are fixed to the door panel before the door trim is mounted, then the mounting strength is improved, but the loss of time increases due to the complex installation sequence at customer sites
Solution Approach 1:
The patent implements preliminary action by pre-assembling the door grip with the integrated bracket and door trim in the factory before delivery to the customer. The bracket is already positioned and configured to extend from the grip portion to the handle portion, and the overlapping portions are pre-aligned. This pre-assembly eliminates the need for complex on-site assembly operations, significantly reducing installation time at customer sites while ensuring proper mounting strength.
3Adaptability or versatility
If the integrated-type cover is attached at the customer site, then the adaptability is improved, but the device complexity increases due to additional assembly steps required
Solution Approach 1:
The patent merges the integrated-type cover attachment into the factory pre-assembly process. The cover is already attached to the door trim in the factory, creating a complete assembly unit. This eliminates the need for additional cover attachment steps at the customer site, reducing assembly process complexity while maintaining the adaptability of the design for different vehicle models and trim levels.

AI summary
A mounting structure of a grip with integrated handle to a door panel includes the grip, a door trim to which the grip is mounted, a bracket, an overlapping portion and a handle fastening portion. The grip includes a grip portion and a handle portion that are integrally formed. The bracket is arranged so as to extend from an end of the grip portion to the handle portion. The overlapping portion includes a part of the grip, a part of the door trim and a part of the bracket held together so as to overlap with one another. The handle fastening portion is provided for fastening the handle portion to the door panel and with which the bracket is to be fixed to the door panel.
