Door Stop With Integral Drive Member for Easy Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door stops are difficult to install and remove, especially in hardwood baseboards, and their design can be aesthetically unpleasing when using additional driving mechanisms, and they lack ease of relocation without damaging the wall or floor.
Innovation Solution
A door stop with an integral driving mechanism featuring a baseplate, a threaded appendage, a center post, and a drive member with various engagement means such as screwdriver slots or hexagonal faces, allowing for easy installation and removal using standard tools, and a removable cap to conceal the drive member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a cylindrical door stop design is used, then the aesthetic appearance is improved, but the ease of installation and removal deteriorates
Solution Approach 1:
The door stop is divided into two functional segments: a cylindrical aesthetic body and a separate drive member with engagement means. This segmentation allows the main body to maintain its pleasing cylindrical shape while the drive member provides the necessary gripping surfaces for tools, resolving the contradiction between aesthetics and ease of installation.
Solution Approach 2:
The drive member with engagement means is extracted as a distinct functional element from the cylindrical body. This extracted drive member can be engaged by driving tools for installation and removal, while the cylindrical body remains aesthetically pleasing, thus resolving the contradiction between shape and ease of operation.
2Ease of operation
If pliers are used to provide increased leverage for installation, then the ease of operation is improved, but the surface of the baseboard deteriorates due to marring
Solution Approach 1:
The drive member acts as an intermediary between the driving tool and the door stop. It provides a dedicated engagement interface that concentrates the installation force on the door stop itself rather than on the baseboard surface, preventing marring while still providing the necessary leverage for installation.
3Reliability
If the door stop is installed in an existing location, then the functionality is achieved, but the time and effort required for repair deteriorates when the location is damaged
Solution Approach 1:
The drive member with engagement means enables the door stop to be easily removed and reinstalled. If the installation location becomes damaged, the door stop can be quickly removed using the drive member, the location repaired, and the door stop reinstalled without considerable time and effort, thus reducing the loss of time while maintaining functionality.
4Ease of operation
If a square or hexagonal surface is added to the door stop for wrench engagement, then the ease of operation is improved, but the device complexity and aesthetic appearance deteriorate
Solution Approach 1:
The engagement means is extracted as a separate drive member distinct from the main cylindrical body. This allows the door stop to maintain its simple cylindrical shape while the extracted drive member provides the necessary geometric surfaces for wrench or screwdriver engagement, avoiding the need to complicate the main body geometry.

AI summary
A door stop includes a first end capable of self-engaging and securing into a support structure adjacent a doorway and a second end having a driving tool adapting means. The driving tool adapting means may, in certain embodiments, involve a single notch, a cross-notch, a cube, a pentagonal tube or a hexagonal tube, capable of receiving conventional driving tools.
