Rotatable Door Holder for Open-Position Hold and Quick Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door stops fail to effectively maintain doors in an open position without obstructing the door's natural swing and require manual adjustment for fit and release.
Innovation Solution
A rotatable door holder apparatus that engages a door stop, allowing adjustable or fixed dimensions, and utilizes flexible structures, springs, or magnetic forces to hold and release doors in an open position, enhancing compatibility and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional door stop is used to limit door swing, then the door is prevented from opening excessively and damaging surrounding areas, but the door cannot be held in an open position
Solution Approach 1:
The door holder apparatus automatically engages with the door stop and floor to hold the door in an open position without requiring manual adjustment. The apparatus self-adjusts to accommodate various door and floor configurations through its rotatable and flexible design, eliminating the need for manual intervention to maintain the door in an open state.
Solution Approach 2:
The apparatus incorporates a rotatable mechanism that allows it to adapt its orientation and position dynamically. This rotational capability enables the apparatus to engage with different door stop positions and floor configurations, providing automatic adjustment without manual intervention while maintaining reliable door holding.
2Adaptability or versatility
If fixed dimension door holder is used, then the structure is simple, but it cannot accommodate various door and floor configurations
Solution Approach 1:
The apparatus features adjustable dimensions through a telescopic or extendable mechanism that allows the user to modify the length of the holding arm. This dynamic adjustment capability enables the apparatus to accommodate various door and floor configurations while maintaining a relatively simple overall structure when not in use.
Solution Approach 2:
The adjustable dimension mechanism utilizes a nested structure where segments of the holding arm can be extended or retracted. When not in use, the apparatus maintains a compact form with nested segments, reducing complexity and space requirements while providing adaptability when needed.
3Reliability
If a door holder apparatus is added to preexisting door stops, then the door can be held open, but the device complexity increases
Solution Approach 1:
The door holder apparatus is designed to work with preexisting door stops, utilizing the existing door stop structure as part of its mounting system. This multi-functional design allows the apparatus to serve multiple purposes: holding the door open, adapting to different configurations, and integrating with existing door stop infrastructure, thereby reducing the need for additional complex components.

AI summary
A door holder having a ring defining a hole, a leg having one end proximate to the ring and a second distal end, the leg having at least one adjustable parameter. The lip is located near the distal end of the leg. A retaining means is located near the ring to fasten the door holder through the hole to a fixed structure, such as a door stop, while allowing rotation of the door holder about the fixed structure.
