Wedge Door Chock for Stabilizing Hinged Man-Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Painting a hinged man-door is challenging due to erratic swivel movement when the door is open, and conventional door stoppers only restrict one direction, making it difficult to paint both sides effectively.
Innovation Solution
A door chock device comprising a connecting rod with two wedges, each having a short leg, a long base, and a sloped hypotenuse, slidably attached through a hinge bracket, which secures the door base by opposing slopes, allowing secure engagement and stabilization of the door in both open positions for efficient painting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional rubber door stopper is used to restrict the door's swivel movement, then the door is stabilized in one direction, but it cannot restrict swivel movement in both directions when painting both sides of the door
Solution Approach 1:
The door stopper device is segmented into two separate wedge members (first wedge and second wedge) that can independently engage with the door from opposite sides. Each wedge can be positioned and engaged separately, allowing the door to be stabilized in different positions for painting either side, thus providing both stability and adaptability
Solution Approach 2:
The wedge members are designed to be movable along the connecting rod, allowing dynamic adjustment of their positions. This enables the wedges to be repositioned to accommodate different door widths and painting requirements, providing adaptability while maintaining stability when engaged
2Ease of operation
If the door is left open for painting, then access to the door surface is improved, but the door erratically swivels on the hinge when contacted by paintbrush, paint roller, or pressurized paint sprayer
Solution Approach 1:
The wedge members are positioned in advance to engage with the door base before painting begins. This preliminary action prevents the door from swiveling when force is applied during painting, as the wedges create friction and mechanical resistance against unwanted movement while allowing the door to remain in the open position for painting
3Reliability
If painter tape is applied to protect gaps between door jam and trim, then protection is provided, but the painting process becomes more time-consuming and complex
Solution Approach 1:
The door stopper device extracts and addresses the root cause of paint leakage by stabilizing the door position and preventing movement that causes paint to enter gaps. By eliminating the movement issue, the need for extensive painter tape application is reduced, thereby maintaining paint precision while improving painting efficiency
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 door chock device stabilizes the hinged man-door, enabling secure painting of both sides without restricting movement, ensuring even coating application and reducing the risk of accidental swivel during the painting process.
Implementation Method 1
the first wedge and the second wedge have opposing slopes adapted to secure a portion of a base of a hinged man-door between the first wedge and the second wedge when the first wedge and the second wedge slide toward each other

AI summary
A door chock device, including: a connecting rod having two ends and two sides; and a first and second wedge, slideably attached to opposites sides of the connecting rod through a hinge bracket attached near the long base of each wedge, the first and second wedges have opposing slopes adapted to secure a portion of a base of a hinged man-door between the first and second wedge when the first and second wedge slide toward each other. Also disclosed is a method of applying a coating to a hung hinged man-door using the man-door chock device.
