Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hardware solutions, such as kick-down doorstops and magnetic devices, are not aesthetically pleasing and lack adjustability to accommodate various door designs, materials, and user preferences, particularly for hollow core doors.
Innovation Solution
A magnetic doorstop and door holder system utilizing magnetic and ferromagnetic materials embedded in door components, allowing for customizable adjustment of magnetic force and positioning to fit different door types and user needs, featuring a hinge pin doorstop body with adjustable legs and magnetic bumpers for secure door holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard kick-down doorstops or basic magnetic devices are used, then door holding function is provided, but aesthetic appearance and adjustability are poor
Solution Approach 1:
The doorstop is divided into separate functional modules: a body portion, an adjustable leg portion with engagement member, and magnetic components. This segmentation allows the leg to be independently adjusted in position and angle while the body remains fixed, providing adaptability without requiring complete redesign of the entire device.
Solution Approach 2:
The engagement member allows the leg to be dynamically adjusted to different positions and angles along the body portion. The adjustable leg can be positioned at various locations and angled to accommodate different door types, weights, and opening angles, transforming a static device into a dynamically adaptable one.
2Force
If magnetic components are added to provide holding force, then door holding effectiveness improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The magnetic components are integrated into the existing doorstop structure rather than being separate add-on elements. The magnets are positioned within the body and leg portions, combining the magnetic holding function with the mechanical support structure, which simplifies manufacturing compared to assembling separate magnetic and mechanical components.
Solution Approach 2:
Traditional mechanical doorstops rely on physical contact and friction between the door and the stop mechanism. This invention replaces part of that mechanical interaction with magnetic attraction between the magnetic components and the door or frame, providing holding force without direct mechanical contact and reducing wear.
3Adaptability or versatility
If adjustable engagement member is implemented to accommodate various door types, then versatility improves, but device complexity increases
Solution Approach 1:
The engagement member is designed to serve multiple functions: it provides adjustment along the body portion, allows angular positioning of the leg, and accommodates different door weights and types. This single component performs what would otherwise require multiple different doorstop designs, achieving universality without proportionally increasing complexity.

AI summary
A magnetic doorstop and door holder provides an aesthetically pleasing, functionally simple, and effective solution to allow homeowners to closely control an amount of force needed to maintain a door in an open position. The system is designed to work with most doors, including traditional solid doors and hollow core doors. The system involves magnetic and/or ferromagnetic materials affixed to or embedded within various entryway components, including doors, door jambs, door frames, and door hinges, and within walls and/or flooring adjacent to the entryway. The system is designed to be highly customizable to fit each homeowner's particular needs and circumstances, and adjustable based on the type of door or entryway layout and based on the homeowner's desired strength of holding and precise positioning.
