Integrated Door Grip Segmentation and Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door designs with integrated grips face complexity in assembly and risk of material tearing due to thermal expansion and force-related issues, and protruding grips can cause damage and safety hazards.
Innovation Solution
A door design featuring a non-protruding grip assembly with straight profiles and a middle wall panel, allowing for flexible assembly and integration into the door panel without visible profiles, and an interchangeable grip system with a fixation element that extends across the door panel for secure attachment of grips at any position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a grip is integrated into the door panel, then the aesthetic finish is improved and protruding hazards are eliminated, but the assembly complexity increases and customization is required
Solution Approach 1:
The grip is divided into multiple segments corresponding to different door panel sections (front section, back section, middle section). Each segment can be independently assembled into its respective panel, allowing the complex integrated grip to be constructed from simpler modular components rather than as a single monolithic piece.
Solution Approach 2:
The grip segments are designed with universal attachment mechanisms that can be integrated into standard door panel configurations. The same grip segment design can be used across different door types and positions, reducing the need for custom-designed grips for each specific application while maintaining the integrated aesthetic.
2Object-affected harmful factors
If a grip is integrated into the door panel, then the aesthetic finish is improved, but the risk of material tearing increases due to thermal expansion and force-related issues
Solution Approach 1:
Attachment elements are pre-installed into the door panels during manufacturing, positioned in advance to accommodate thermal expansion and contraction. These pre-positioned elements provide buffered attachment points that can absorb dimensional changes without causing stress concentrations that would lead to material tearing at the grip-panel interface.
Solution Approach 2:
The grip assembly uses composite construction with different materials for the grip segments and attachment elements, allowing each component to be optimized for its specific function. The attachment elements are designed to accommodate differential thermal expansion between the grip material and door panel material, preventing stress buildup that could cause tearing.
3Strength
If profiles are used to form the grip, then the structural integrity is improved, but visible profiles are created which compromise the aesthetic finish
Solution Approach 1:
The grip segments are nested within recesses or openings in the door panels, with the attachment elements positioned to hold the grip segments from behind or within the panel thickness. This nesting arrangement provides the necessary structural support through the attachment mechanism while keeping the grip segments flush with or recessed into the panel surface, eliminating visible protruding profiles.

AI summary
The invention involves a door comprising a door panel that has a front surface and a back surface of the door and a grip integrated into the door panel which extends from the front side to the back side of the door panel, wherein the grip is formed so that users can open/close the door. The grip is formed by an assembly that extends substantially in a full dimension from the front and back surface. The invention also involves an assembly comprising a door and at least one interchangeable grip, wherein the door is comprised of a door panel that forms a front surface and a back surface of the door and a fixation element integrated into the door panel and extends from the front surface to the back surface of the door panel, wherein the fixation element is provided for the removable fixation of at least one interchangeable grip. The fixation element is formed by an assembly that extends substantially in a full dimension from the front and back surface.
