Clamping Pin Mounting Plate Assembly for Door Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for door hinges to door frames are cumbersome and inflexible, particularly with spacers that require complex manufacturing and handling, leading to issues with alignment and stability, especially with varying door frame thicknesses and depths.
Innovation Solution
A fastening plate arrangement with a clamping pin and spacers that allow for modular adjustment, where the clamping pin has a shaft section and a larger head to secure spacers in place, enabling flexible positioning and secure attachment without the need for complex spacer handling, and using a plastic clamping pin for a frictional connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spacers are made with tongues and grooves for stacking, then adaptability to varying door frame thicknesses is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The spacer is divided into multiple individual elements that can be stacked to achieve different total thicknesses. Each spacer element has a through-opening that accommodates a common clamping pin, allowing multiple spacers to be stacked and secured together as a unit without requiring complex tongue-and-groove interlocking structures.
2Ease of operation
If spacers are clamped in the receiving opening, then ease of operation is improved, but reliability decreases due to risk of loss during transport
Solution Approach 1:
The clamping pin serves multiple functions simultaneously: it clamps the spacer elements to the mounting plate for easy positioning and operation, and it also connects all spacer elements together as a unified stack. This dual function eliminates the risk of spacer elements becoming separated or lost during transport while maintaining ease of operation during installation.
3Adaptability or versatility
If multiple spacer types are manufactured, then adaptability to different configurations is improved, but manufacturing precision requirements increase to ensure smooth fitting
Solution Approach 1:
A single clamping pin design with a through-opening is used universally for all spacer elements, regardless of their individual thicknesses or configurations. This standardized interface allows spacer elements of varying dimensions to be stacked and secured using the same clamping mechanism, reducing manufacturing precision requirements compared to specialized tongue-and-groove interfaces that require precise matching.
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
This solution simplifies the handling and positioning of spacers, ensuring secure attachment and alignment, allowing for pre-configuration and easy adjustment during assembly, reducing the risk of spacers falling out and accommodating varying door frame thicknesses and depths.
Implementation Method 1
The clamping pin is received by a through-opening of the spacer and a receiving opening arranged on the door hinge receiving section into which the clamping pin is inserted. The frictional connection secures the spacers in position without requiring additional fastening elements.
