Resilient Shower Door Jamb Seal for Adhesive Watertight Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower door seals fail to effectively maintain the closed position of shower doors and prevent water leakage, often requiring cumbersome installation methods involving mechanical fasteners and rigid materials that can damage doors.
Innovation Solution
A resilient U-shaped wall jamb with pressure-sensitive adhesive and flexible legs that self-align with the shower door panel, eliminating the need for separate bumpers and mechanical fasteners, and allowing for easier installation by using the door panel as a guide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional rigid wall jambs with mechanical fasteners are used, then structural strength is improved, but installation complexity and potential door damage increase
Solution Approach 1:
The patent replaces mechanical fastening systems (screws, bolts, drilling) with an adhesive bonding system. The wall jamb uses adhesive applied to the back surface to bond directly to the shower door panel, eliminating the need for mechanical fasteners and drilling operations. This substitution maintains structural strength while dramatically simplifying installation and preventing door damage.
Solution Approach 2:
The patent changes the bonding mechanism from mechanical (physical fasteners) to chemical (adhesive bonding). By using adhesive with appropriate bonding strength and surface preparation, the system achieves comparable or superior structural strength while eliminating complex installation procedures and potential damage from drilling and fastening.
2Reliability
If conventional seals are used, then water sealing is provided, but the closed position of shower doors cannot be maintained
Solution Approach 1:
The patent combines multiple functions into a single integrated wall jamb component: water sealing, door position maintenance through friction, and structural attachment. The resilient material provides both the seal and the frictional force needed to hold the door closed, eliminating the need for separate sealing components and position-maintenance mechanisms.
Solution Approach 2:
The wall jamb is designed as a multi-functional component that simultaneously provides water sealing, structural support, door position maintenance through friction, and shock absorption. The resilient material properties enable it to perform multiple functions that would traditionally require separate components, improving both reliability and ease of operation.
3Ease of operation
If resilient material is used for wall jamb, then ease of installation and adaptability are improved, but structural strength may be reduced
Solution Approach 1:
The patent employs composite material construction, combining resilient material (for flexibility and ease of installation) with rigid reinforcement elements (for structural strength). The resilient base material provides adaptability and ease of installation, while embedded rigid components or layers provide the necessary structural strength to support the shower door and maintain sealing integrity.
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
The solution provides a watertight seal, maintains the closed position of the shower door, decelerates door closure, and simplifies installation by eliminating the need for drilling and mechanical fasteners, while being aesthetically pleasing and adaptable to uneven door installations.
Implementation Method 1
a pressure sensitive adhesive disposed at an exterior surface of the base. The pressure sensitive adhesive is configured to adhere to a wall of the showering enclosure.
Implementation Method 2
The plurality of legs and the base are formed of a resilient material
Implementation Method 3
provides a water barrier between the connection of the shower door panel and a shower wall which may or may not maintain the closed position of the shower door panel, or decelerate it upon closing
