RV Screen Door Strap Assembly for Automatic Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for RV screen doors are not user-friendly, safe, and reliable, often impeding normal movement and failing to consistently prevent bugs and debris from entering, as they require manual operation and lack efficient automatic closing mechanisms.
Innovation Solution
A strap member assembly with a first flat-hooked member and a deformable strap, allowing unobstructed opening and automatic closing of the screen door, comprising a V-shaped hook for secure attachment to the screen door access panel and a second hook for the frame, utilizing a rubber band for tension-based closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a manual closing mechanism is used for the screen door, then the device complexity is reduced, but the reliability of automatic closing is worsened
Solution Approach 1:
The screen door system performs closing action automatically without human intervention. The elastic band stores potential energy when the door is opened, and this stored energy automatically pulls the door closed when released, making the system self-serving and eliminating the need for manual operation.
Solution Approach 2:
The elastic band is pre-stretched and attached to the door frame and door panel before use. This preliminary action stores potential energy in the elastic band, which is then released to automatically close the door, eliminating the need for manual closing effort at the time of use.
2Adaptability or versatility
If the screen door is designed to slide for outer door access, then the adaptability is improved, but the reliability of insect prevention is worsened
Solution Approach 1:
The elastic band automatically pulls the screen door closed after the user enters or exits through the outer door. This self-acting mechanism ensures the door returns to its closed position without requiring the user to remember or manually close it, thereby maintaining insect prevention reliability.
Solution Approach 2:
The elastic band provides a mechanical feedback system where opening the door stretches the band, storing energy that then automatically pushes the door back to the closed position. This feedback mechanism ensures the door consistently returns to the correct state for insect prevention.
3Ease of operation
If the screen door requires manual closing, then the ease of operation is improved, but the loss of time is worsened
Solution Approach 1:
The door closing action is performed automatically by the elastic band mechanism without requiring the user to manually pull or push the door closed. This eliminates the time users would otherwise spend on the closing action while maintaining ease of operation.
Solution Approach 2:
The elastic band is pre-positioned and pre-stretched during installation, so that when the door is opened, the stored energy is immediately available to automatically close the door. This preliminary preparation eliminates the need for users to perform closing actions during each use.
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
Enables unobstructed opening and automatic closing of RV screen doors, preventing bugs and debris entry while maintaining normal movement, with a simple, affordable, and user-friendly design.
Implementation Method 1
a deformable strap having a proximate end, and a distal end

AI summary
A tool for enabling opening and closing a screen door of a recreation vehicle system includes a strap member assembly having a first end including a first flat-hooked member; a deformable strap having a proximate end, and a distal end; and a second end having a second flat-hooked member. The tool for enabling opening and closing a screen door of a recreation vehicle system includes the strap member assembly. When used the strap member assembly does not impede normal movement of screens of the recreation vehicle while simultaneously enabling manipulation of the screen door between an open position to allow ingress and a closed position to prevent bugs and debris from entering into the recreation vehicle, as desired.
