Patch Fitting Damping for Glass Door Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concealed floor door closers for glass doors require complex installation processes and cutting of the floor, and can lead to instability and potential damage or breakage due to the glass door offsetting over time.
Innovation Solution
A patch fitting comprising a mount, shaft, clamping seat, and piston unit that provides damping resistance through hydraulic oil pressure, allowing for easy installation without cutting the floor and compensating for glass door offsets, featuring an adjustable mount and piston unit that interacts with an eccentric cam to manage opening and closing forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a concealed floor door closer is used to support the glass door, then the reliability and weight-bearing ability are improved, but the installation process becomes complicated and requires cutting the floor
Solution Approach 1:
The invention divides the door support system into modular components: a mount with mounting plate, a separate shaft with eccentric cam, a clamping seat with piston unit, and adjustment members. This segmentation allows each component to be manufactured and adjusted independently, simplifying installation while maintaining reliability.
Solution Approach 2:
The invention introduces a patch fitting as an intermediary component between the floor and the glass door. This patch fitting includes the mount, shaft, and clamping seat assembly that can be installed on the floor surface without cutting, serving as a mediator that transfers and distributes the door weight while simplifying installation.
2Reliability
If a concealed floor door closer is used to hold the glass door, then the weight-bearing ability is improved, but the installation time increases due to waiting periods
Solution Approach 1:
The invention allows the mount and clamping seat assembly to be pre-assembled and adjusted before final installation. The adjustment members can be pre-positioned to accommodate potential door offsets, and the piston unit can be pre-filled with hydraulic oil, reducing on-site installation time and eliminating waiting periods.
Solution Approach 2:
The invention incorporates adjustable components that can be dynamically tuned during installation. The adjustment members allow for real-time positioning adjustments, and the piston unit can be adjusted to provide appropriate damping forces, enabling rapid adaptation to different installation conditions without extended waiting periods.
3Ease of operation
If the glass door is supported by hinges, then the ease of operation is improved, but the stability deteriorates after long use due to pivot instability
Solution Approach 1:
The invention employs a piston unit with hydraulic oil in the clamping seat to provide damping resistance. This hydraulic mechanism absorbs shocks and dampens the sweeping movement of the glass door, maintaining stability over time while preserving smooth operation. The hydraulic damping compensates for wear and maintains consistent performance.
Solution Approach 2:
The invention changes the support mechanism from simple mechanical hinges to a system with adjustable parameters including hydraulic damping force, eccentric cam position, and clamping seat tension. These adjustable parameters allow optimization of both operational smoothness and long-term stability, preventing the degradation seen in fixed hinge systems.
4Reliability
If a patch fitting with piston unit is used, then the damping resistance is improved, but the device complexity increases
Solution Approach 1:
The invention merges the piston unit with the clamping seat into a single integrated component. The piston unit is installed within the oil chamber of the clamping seat, combining the damping function with the door clamping function. This merging reduces the number of separate components and simplifies the overall structure while maintaining effective damping resistance.

AI summary
A patch fitting (10) for a glass door (12) includes a mount (20) for being mounted on a floor, a shaft (30) connected with the mount, a clamping seat (40) pivotally connected with the shaft (30), and a piston unit (50) installed inside the clamping seat. When the glass door (12) is sweeping to open or close, the clamping seat (40) will turn along with the sweeping movement of the glass door about the shaft (30) and the piston unit (50) will be pushed by an eccentric cam (34) of the shaft (30) to press the hydraulic oil contained in the clamping seat so as to provide a damping resistance in response to the sweeping movement of the glass door. The patch fitting can be easily installed on the floor by a simple work.
