Pivot door assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pivot door assemblies are inconvenient and time-consuming to mount, as they require drilling, which can damage the frames and is not acceptable for users.
Innovation Solution
A pivot door assembly design that allows for easy assembly without drilling, using a stationary frame with an upper adjusting block and movable frame with detachable hinge bases, where a screw connects through a slot to adjust the relative position between the frames, eliminating the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional drilling and fastening method is used to mount pivot door frames, then the connection strength is improved, but the installation time and complexity increase significantly
Solution Approach 1:
The mounting system is divided into separate modular components: a mounting block with pre-formed connection features and a frame assembly with corresponding engagement structures. This segmentation allows the components to be assembled without drilling, as each piece has pre-integrated connection elements that interlock mechanically.
Solution Approach 2:
The mounting blocks are pre-formed with integrated connection features (such as recesses, protrusions, or snap-fit structures) during manufacturing, rather than requiring on-site drilling and fastening. This preliminary preparation of connection interfaces enables rapid assembly by simply engaging the pre-formed features.
2Reliability
If drilling operation is performed to mount the frames, then the connection reliability is improved, but the frames may be damaged or scored
Solution Approach 1:
The mounting function is separated from the frame structure itself, using independent mounting blocks that attach to the frame through non-damaging mechanical engagement. This prevents drilling operations from directly affecting the frame material, avoiding scores and scratches.
Solution Approach 2:
The mounting block acts as an intermediary component between the wall and the frame. It provides the drilling and fastening functions while the frame only needs to engage with the mounting block through simple mechanical features, avoiding direct drilling of the frame material.
3Stability of the object's composition
If traditional fastening method is used, then the structural stability is improved, but the ease of assembly and adjustment is reduced
Solution Approach 1:
The mounting system incorporates adjustable and detachable connection features, allowing the mounting blocks to be easily positioned and secured at different locations. The mechanical engagement features (such as slots, tabs, or snap-fit mechanisms) provide stable connection while enabling simple assembly and disassembly without specialized tools.
Solution Approach 2:
The mounting blocks and frame components are designed with self-aligning and self-securing features that automatically engage when brought together, reducing the need for precise alignment and manual fastening operations. The design enables users to assemble the structure through simple mechanical engagement rather than complex drilling and fastening procedures.

AI summary
A pivot door assembly is provided comprising a stationary frame, an upper adjusting block located on an upper end of the stationary frame and having a slot, a movable frame having detachable hinge bases including an upper hinge base and a lower hinge base, each of the hinge bases being provided with a hinge shaft for connecting with a pivot door, and a first screw, wherein a first screw hole is disposed on the upper hinge base, a second screw hole is disposed on an upper end of the movable frame, and when a relative position of the stationary frame and the movable frame is determined, the first screw can pass through the slot and the first screw hole to connect into the second screw hole.
