Composite Door Trim Structure with Flush Partition Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing doorframe systems are aesthetically unpleasing due to protruding vertical uprights, require multiple types to accommodate varying partition thicknesses, and suffer from thermal expansion issues leading to cracks at the join with the partition.
Innovation Solution
A trim structure made from composite panels, identical to the partition, with adjustable thickness to match the partition, forming a flush exterior surface and incorporating a transverse end wall with a projecting element for the door, eliminating the need for separate doorframes and reducing thermal expansion issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional doorframes are used, then the door can be accommodated and functional requirements are met, but the vertical uprights protrude from the partition surface creating aesthetic issues
Solution Approach 1:
The trim structure merges the doorframe function with the partition material by using composite panels identical to the partition. The lateral walls form exterior surfaces that are flush with the partition, eliminating protruding uprights and creating a seamless appearance.
Solution Approach 2:
The trim structure uses the same material as the partition locally at the visible surfaces, while the internal structure can differ. The lateral walls have exterior surfaces made of composite panel material matching the partition, providing aesthetic consistency without compromising structural function.
2Adaptability or versatility
If multiple types of doorframes are used to accommodate varying partition thicknesses, then adaptability is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The trim structure is designed with adjustable thickness through the spacing of lateral walls, which can be configured to match different partition thicknesses. This dynamic adjustability eliminates the need for multiple fixed types of doorframes.
Solution Approach 2:
The trim structure serves multiple functions: it accommodates doors, matches various partition thicknesses, and provides aesthetic continuity. This universal design replaces the need for multiple specialized doorframe types.
3Strength
If doorframes made of different material than the partition are used, then structural requirements are met, but thermal expansion differences cause cracks at the join
Solution Approach 1:
The trim structure uses composite panel material identical to the partition, creating homogeneity in material composition. This eliminates differential thermal expansion between dissimilar materials, preventing cracks at the join between doorframe and partition.
4Ease of operation
If separate doorframes are installed, then door accommodation is achieved, but additional on-site work duration and cost increase
Solution Approach 1:
The trim structure combines the doorframe installation with the partition installation process. By integrating the door accommodation function into the partition structure itself, separate doorframe installation steps are eliminated, reducing on-site work duration and cost.

AI summary
A trim structure intended on one hand to receive a door, in particular an internal door, and on the other hand to be joined to a partition. The structure includes two lateral walls facing one another and spaced apart by a thickness. The thickness being adjusted with respect to the thickness of the partition such that the lateral walls form an external surface that is flush with the external surface of the partition when the structure is joined to the partition. A transverse end wall connects the two lateral walls. The transverse end wall includes a planar surface that is configured to butt up against the thickness of a vertical edge face of the door and a projecting element forming a bearing surface for the door. The walls being formed from at least one composite panel, the panel comprising a central layer sandwiched between two facing layers.
