Adjustable Pivot Door Hinge Assembly for Precise Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pivoting doors are difficult to install due to imperfections in floors and ceilings, requiring lengthy and imprecise repositioning of hinges, which cannot be intuitively adjusted without dismantling.
Innovation Solution
A pivoting door with a hinging assembly featuring adjustable fixed and movable bodies, allowing lateral, axial, and rotational adjustments through guide and transmission mechanisms, enabling precise positioning without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hinges are rigidly fixed to ceiling and floor, then door structure is stable, but installation is difficult and time-consuming due to inability to reposition
Solution Approach 1:
The hinge system transitions from a static rigid connection to a dynamic adjustable connection. The movable body can slide within the fixed body along adjustment axes, allowing the hinge position to be modified during installation to accommodate floor and ceiling imperfections, thereby reducing installation time while maintaining structural stability once positioned.
Solution Approach 2:
The hinge is divided into separate components: a fixed body rigidly attached to the ceiling or floor, and a movable body that can be repositioned relative to the fixed body. This segmentation allows the stable connection to be maintained while enabling easy adjustment and repositioning during installation.
2Reliability
If hinges are rigidly fixed to ceiling and floor, then door structure is stable, but repositioning requires dismantling which is complex and time-consuming
Solution Approach 1:
The hinge incorporates a movable body that can slide within the fixed body along adjustment axes, transforming the static connection into a dynamic one. This allows the hinge to be repositioned without dismantling by simply moving the movable body to a new position and securing it, maintaining structural stability while greatly easing repositioning operations.
Solution Approach 2:
The hinge design anticipates future repositioning needs by incorporating adjustment mechanisms from the beginning. The movable body is designed to slide within the fixed body along predetermined adjustment axes, allowing repositioning to be performed easily without dismantling, thus preparing the system in advance for potential adjustments.
3Ease of operation
If swing leaf is not squared up due to floor/ceiling imperfections, then door cannot be opened/closed easily, but repositioning hinges requires dismantling
Solution Approach 1:
The hinge system allows dynamic adjustment of the swing leaf position relative to the ceiling and floor through the movable body's ability to slide within the fixed body. This enables the swing leaf to be squared up properly despite floor and ceiling imperfections, ensuring easy door operation while avoiding complex dismantling procedures through a simple sliding adjustment mechanism.
4Ease of manufacture
If hinges are fixed without adjustment capability, then manufacturing is simple, but installation precision is poor due to floor/ceiling imperfections
Solution Approach 1:
The hinge incorporates a movable body that can slide within the fixed body along adjustment axes, adding minimal manufacturing complexity while significantly improving installation precision. This allows the hinge to be precisely positioned to compensate for floor and ceiling imperfections, achieving proper alignment without requiring extremely precise initial manufacturing of the entire assembly.
