Adjustable Door Hinge With Half-Shell Assembly And Eccentric Trim
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable hinges for doors and windows are complex to assemble, requiring labor-intensive operations and inaccessible adjustment mechanisms when installed, making them difficult to adjust in place and automate.
Innovation Solution
The hinge design features a containment body composed of two half-shells that simplify assembly and provide accessible adjustment mechanisms via eccentric elements, slider systems, and screws, allowing for angular and positional adjustments with standard tools like Allen wrenches, even when installed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the containment body is constituted by a single part, then the structural integrity is improved, but the assembly complexity increases significantly
Solution Approach 1:
The containment body is divided into two separate half-shells that are assembled together. This segmentation allows the pintle supporting block and adjustment elements to be pre-assembled and inserted into the containment body more easily, reducing assembly complexity while maintaining structural integrity through the joined half-shells.
2Ease of manufacture
If the adjustment means are accessible only when the containment body is extracted from its seat, then the manufacturing simplicity is improved, but the ease of operation deteriorates
Solution Approach 1:
The adjustment means are nested within the containment body structure, with adjustment openings provided in the half-shells that allow access to adjustment elements even when the containment body is mounted in its seat. This nested design enables in-situ adjustments without requiring disassembly of the hinge from the jamb.
3Manufacturing precision
If the containment body is made as a single part, then the manufacturing precision is improved, but the productivity decreases due to labor-intensive assembly
Solution Approach 1:
The pintle supporting block and adjustment elements are pre-assembled together as a sub-assembly before being inserted into the containment body. This preliminary action simplifies the final assembly operation and enables automation, improving productivity while maintaining manufacturing precision through standardized pre-assembled units.
4Device complexity
If the adjustment means require specialized access procedures, then the device complexity is reduced, but the ease of operation worsens
Solution Approach 1:
The adjustment means are designed to be accessible through openings in the half-shells, allowing the hinge to be self-adjusting in the field without requiring specialized tools or complex disassembly procedures. The adjustment elements can be operated directly through the containment body structure, making the system self-service friendly for installation technicians.
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 design results in a quicker, simpler assembly process and accessible adjustments, reducing labor costs and enabling intuitive management by technicians, facilitating easier installation and adjustment without removing the hinge from its seat.
Implementation Method 1
the means for adjusting the angular trim of the pintle supporting block with respect to the containment body about a rotation axis that is parallel to the axis of the pintle
Implementation Method 2
The adjustment means, usually controlled by threaded elements or cam elements that can be rotated by means of a corresponding Allen wrench or screwdriver
Implementation Method 3
a mounting arrangement for a wing of a window or door, comprising a wing part and a frame part, which are pivotally coupled together about a pivot axis
Implementation Method 4
a longitudinal adjustment mechanism having self-locking characteristics
