Pocket Door Mounting With Dampener-Based Slamming Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door mounting systems, particularly for sliding doors, lack effective mechanisms to prevent slamming and provide smooth, controlled movement between open and closed positions.
Innovation Solution
A door mounting system incorporating a dampener assembly, actuator arm, stop member, and door hanger, which includes a track with an upper and lower flange, and a connecting section, to control the door's movement and prevent slamming by using a dampener mechanism and an actuator arm to resist the door's motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple track and roller mechanism is used for door mounting, then the device complexity is reduced and ease of manufacture is improved, but the door lacks effective slamming prevention and controlled movement
Solution Approach 1:
A dampener assembly is introduced as an intermediary component between the door hanger and track system. The dampener assembly includes a dampener mechanism with a rod that interacts with a trigger mechanism, serving as a mediator to control door movement and prevent slamming without requiring complete redesign of the entire door mounting system.
Solution Approach 2:
The dampener mechanism applies preliminary counteracting force to the door's motion before slamming occurs. The trigger mechanism with actuation member is positioned to engage with the dampener rod, creating preliminary resistance to door movement in the closed direction, thereby preventing the harmful slamming effect before it can occur.
2Reliability
If a dampener mechanism with trigger and actuator arm is added to control door motion, then slamming prevention and controlled movement are improved, but the device complexity increases
Solution Approach 1:
The door mounting system is segmented into distinct functional modules: the track system for support, the door hanger for suspension, and the dampener assembly for motion control. The dampener assembly itself is segmented into the dampener mechanism, trigger mechanism, and actuator arm, allowing each component to be designed, manufactured, and maintained independently while working together to prevent slamming.
3Object-affected harmful factors
If the actuator arm engages the trigger mechanism to resist door motion, then controlled movement and noise reduction are improved, but the mechanism requires precise positioning and alignment
Solution Approach 1:
The actuator arm and trigger mechanism are designed with dynamic engagement characteristics. The actuator arm can engage and disengage from the trigger's actuation member based on door position and motion conditions. This dynamic interaction allows the system to adapt to manufacturing tolerances and maintain effective slamming prevention without requiring extremely precise static alignment, as the engagement is optimized during actual door operation.

AI summary
A pocket door mounting system includes a dampener assembly, an actuator arm, a stop member and a door hanger. The dampener assembly includes a housing having a first end having an opening, a second end, a roller mechanism pivotally connected to the second end, and a dampener mechanism. The damper mechanism has a trigger for actuating the dampener mechanism. The actuator arm has a first end and a second end. The door hanger has a bracket having an opening. A pin extends through the opening in the dampener assembly and the opening in the door hanger to connect the dampener assembly to the door hanger.
