Portable Doorstop Clip for Varying Thickness and Swing Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing doorstop assemblies are not portable enough to be easily moved between doors of varying thickness and direction, often causing damage when removed due to their fixed mounting hardware and complex designs with multiple moving parts.
Innovation Solution
A portable doorstop assembly featuring a spring steel clip with a dual lock leg that can be easily secured and reoriented to accommodate different door thicknesses and swinging directions, using spring tension, pivots, and optional support means like Velcro or magnets to prevent damage and facilitate easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting hardware is used to secure doorstops to doors, then the doorstop is firmly attached and reliable, but the doorstop cannot be easily moved or removed without leaving holes or damage
Solution Approach 1:
The patent replaces traditional mechanical mounting hardware (screws, bolts, or adhesive) with a spring-loaded clip mechanism that uses elastic deformation and spring tension to secure the doorstop. The clip engages with the door edge through mechanical interlocking while allowing easy release by applying force to the release lever, enabling reliable attachment without permanent modification to the door surface
Solution Approach 2:
The doorstop incorporates a dynamic clip mechanism with movable parts including a spring-loaded arm and release lever. The spring provides continuous holding force to maintain secure attachment, while the lever mechanism allows controlled release. This dynamic design transitions between locked and unlocked states, combining firm attachment with ease of removal
2Adaptability or versatility
If doorstop assemblies are designed to accommodate varying door thickness, then versatility is improved, but the design becomes more complex with multiple moving parts
Solution Approach 1:
The clip mechanism uses a flexible spring-loaded arm that can dynamically adjust its position and angle to accommodate different door thicknesses. The spring's elastic properties allow the arm to bend and flex as needed, providing adaptability without requiring multiple discrete components or complex adjustment mechanisms
Solution Approach 2:
The design changes the physical parameters of the spring-loaded arm, including its length, stiffness, and angle of attachment, to accommodate varying door thicknesses. By optimizing these parameters, the single clip mechanism can adapt to different door sizes without requiring multiple specialized components
3Adaptability or versatility
If multiple moving parts are used in doorstop assemblies to accommodate varying door thickness, then adaptability is improved, but the probability of mechanical failure increases
Solution Approach 1:
The patent combines multiple functions into a single integrated clip mechanism. The spring-loaded arm simultaneously provides the holding force, the angle adjustment, and the thickness accommodation that would traditionally require separate components. This consolidation reduces the number of potential failure points while maintaining adaptability
Solution Approach 2:
By optimizing the spring's physical parameters (stiffness, length, material properties) and the geometric parameters of the clip mechanism, the design achieves reliable operation across a range of door thicknesses without requiring multiple specialized components, thereby reducing mechanical failure probability
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 damage-free, easy-to-install-and-remove doorstop that can be used on various door thicknesses and directions without leaving holes or damage, ensuring versatility and reliability.
Implementation Method 1
The design of the portable door clip provides a means of affixing the entire portable doorstop assembly to a door of varying thickness by employing a spring tension
Implementation Method 2
A dual lock leg is pivotally mounted on the face of the first front side of the portable door clip such that the pivotal mounting allows the dual lock leg to move from an essentially upward vertical stowed position to an essentially downward floor engaging position
Implementation Method 3
The dual lock leg is provided a support means for a dual lock capability such that it may be locked in an upward vertical stowed position even though the entire doorstop assembly may be rotated upside down prior to installation onto a door

AI summary
Disclosed is a doorstop assembly which allows a doorstop to be conveniently installed or removed from left or right swinging doors of varying thicknesses. The assembly has a portable door clip which may be easily pulled off a left swing door, turned upside down, and then pushed into place onto a right swing door. The portable door clip can firmly embrace doors of varying thickness. A dual lock leg mounted to the front of the door clip can be stowed in an upward position regardless of which way the door clip is turned, and then lowered toward the floor surface when in use to stop the door from closing.
