Width-Adjustable Air-Communicating Trim Molding for Passive Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trim moldings, such as door casings and baseboards, do not effectively facilitate passive ventilation without altering the aesthetics or requiring costly modifications, and there is a need for a low-cost solution that enhances air exchange in residential and commercial construction.
Innovation Solution
The development of air communicating trim moldings with integrated air passageways and adjustable width capabilities, allowing for airflow through edge openings and adjustable installation to fit various widths, ensuring seamless integration with existing structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trim molding is made airtight to improve sealing performance, then air leakage is reduced, but passive ventilation capability is lost
Solution Approach 1:
The trim molding is segmented into multiple functional zones: a sealed exterior face for aesthetic and weatherproofing purposes, and an interior air passageway system with edge openings that enables passive ventilation. This segmentation allows the molding to simultaneously achieve airtight sealing on the visible surface while providing controlled air exchange through internal channels and perimeter openings.
Solution Approach 2:
An air passageway system acts as an intermediary between the sealed exterior environment and the interior space. The passageways conduct air from edge openings along the perimeter to interior locations, enabling ventilation without compromising the sealed appearance or weatherproofing of the trim molding's exterior face.
2Object-generated harmful factors
If ventilation openings are added to the door or window itself, then passive ventilation is improved, but aesthetics are degraded and manufacturing cost increases
Solution Approach 1:
The ventilation function is extracted from the door or window itself and relocated to the trim molding. The trim molding incorporates air passageways and edge openings that provide passive ventilation without requiring any modifications to the door or window panels, thereby preserving their aesthetic appearance while improving air quality.
Solution Approach 2:
The ventilation function is copied from traditional vented door designs and implemented in the trim molding instead. This allows the door to maintain its solid, aesthetic appearance while the trim molding replicates the ventilation capability through its own integrated air passageway system.
3Ease of manufacture
If fixed width trim molding is used, then manufacturing is simplified, but adaptability to different opening widths is reduced
Solution Approach 1:
The trim molding incorporates adjustable width components that allow the assembly to be dynamically configured to match different opening widths. The molding can be adjusted during installation to accommodate variations in door and window frame dimensions while maintaining the integrated air passageway system and aesthetic appearance.

AI summary
The present concept is an air communicating trim molding for installation as a baseboard and a casing is of pre-selected longitudinal length and includes a bottom surface, a top surface, and an intermediate surface spaced between the bottom and top surface, wherein the bottom surface abuts against a wall surface in an installed position. An air passageway communicates exterior air into and out of the air passageway, wherein the air passageway includes the space between the wall surface and the intermediate surface and communicate air along the air passageway when the trim molding is in an installed position. The air communicating trim molding includes edge openings wherein the edge openings communicate exterior air into and out of the air passageways. It further includes protrusions of preselected size extending laterally between the intermediate surface and the bottom surface and dimensioned and spaced apart to create the edge openings.
