Hinge-Integrated Adjustable Door Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door stop mechanisms are limited in adjustability, aesthetically unappealing, and can cause damage to doors and walls, while also increasing costs and posing trip hazards due to their separate component nature and installation requirements.
Innovation Solution
A hinge-integrated door stop mechanism where the door stop element is hidden within the knuckles of the hinge, allowing for adjustable door positioning without external components, reducing visual impact and potential damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wall-mounted door stops are used, then door stopping function is provided, but they protrude from the wall and are visually unappealing and pose trip hazards
Solution Approach 1:
The door stop function is merged with the hinge assembly, combining two previously separate components (hinge and door stop) into a single integrated unit. The door stop element is positioned within the hinge structure, eliminating the need for separate wall-mounted stops and their associated aesthetic and safety issues.
Solution Approach 2:
The door stop function is extracted from external wall-mounted components and relocated to the hinge assembly itself. This extraction eliminates the protruding elements from the wall that caused aesthetic and trip hazard problems while maintaining the door stopping capability.
2Reliability
If separate door stop components are used, then door stopping is achieved, but costs increase and installation complexity increases
Solution Approach 1:
The hinge and door stop are merged into a single integrated assembly, reducing the total number of components from two separate items to one unified component. This simplification reduces installation complexity and potential failure points while maintaining reliable door stopping functionality.
3Adaptability or versatility
If conventional door stops are used, then door positioning is provided, but adjustability is limited and relocation is difficult
Solution Approach 1:
The hinge assembly incorporates adjustable features that allow the door stop position to be dynamically changed. The design enables the hinge to be relocated or repositioned along the door edge, providing adaptability for different door positions and configurations while maintaining ease of installation and relocation.
4Adaptability or versatility
If hinge-mounted door stops with arms are used, then adjustability is improved, but visual appeal deteriorates and damage to doors occurs
Solution Approach 1:
The door stop element is nested within the hinge structure itself, concealed inside the hinge assembly rather than extending outward as separate arms. This nesting approach maintains adjustability while eliminating the visual unappeal of exposed arms and preventing damage to hollow-core doors that occurs with protruding stop elements.

AI summary
A hinge has a hinge-integrated stop. The hinge includes a first hinge leaf having a substantially-planar portion with a pivot edge and a top edge. The first hinge leaf includes a first knuckle extending from the pivot edge of the substantially-planar portion near the top edge. The first knuckle of the first leaf includes an inner splined surface. The hinge also includes a second hinge leaf having a substantially-planar portion having a pivot edge. A first knuckle extends from the pivot edge of the substantially-planar portion of the second hinge leaf, where the first knuckle has an inner surface and a first knuckle stop element on the inner surface. A hinge pin has a shaft having a shaft diameter and an upper splined portion having fingers extending beyond the shaft diameter and a hinge pin stop element located on the shaft below the upper splined portion.
