Sliding Hinging Door Carriage Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional patio door systems either lack flexibility in opening size and space utilization or are cumbersome to operate, as they either provide insufficient space for ingress and egress or require complex mechanisms for both sliding and swinging functionalities.
Innovation Solution
A door assembly with a first and second carriage assembly and locking mechanisms that allow the door to pivot or slide, featuring a hinge pin and linear motion devices to switch between configurations, enabling intuitive operation and maximizing opening space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sliding patio doors are used to vary opening size, then flexibility in opening size is improved, but space for ingress and egress is reduced to approximately half of swinging doors
Solution Approach 1:
The door assembly is designed to perform multiple functions through a single integrated structure. The door can operate in both sliding mode (for variable opening sizes) and swinging mode (for maximum ingress/egress space) by using a universal carriage assembly that supports both movement types along the track system
Solution Approach 2:
The door system transitions from static functional modes to dynamic switching between modes. The carriage assembly can be repositioned along the track to change the door's operational characteristics, allowing the system to adapt its behavior based on the desired function whether sliding for weather protection or swinging for maximum access
2Area of moving object
If swinging patio doors are used to maximize space for ingress and egress, then space for ingress and egress is improved, but flexibility in opening size is reduced and wind/air/water resistance is insufficient
Solution Approach 1:
The door assembly integrates both swinging and sliding capabilities into a single door unit. The carriage assembly supports both rotational movement (swinging) and lateral movement (sliding), allowing the door to provide maximum ingress/egress space when swung open while also enabling variable opening sizes and weather protection when slid to overlap with the other door
3Object-affected harmful factors
If sliding patio doors are configured to overlap for weather protection, then wind/air/water resistance is improved, but space for ingress and egress is reduced
Solution Approach 1:
The system dynamically switches between overlapping configuration (for weather protection) and non-overlapping swinging configuration (for maximum access). The carriage assembly can be positioned to allow the door to swing fully open without obstruction, providing maximum ingress/egress space while maintaining the ability to overlap when weather protection is needed
4Adaptability or versatility
If complex hinging mechanisms are used to accomplish both sliding and swinging functionality, then versatility is improved, but device complexity increases
Solution Approach 1:
A single universal carriage assembly serves multiple functions by supporting both sliding and swinging operations. The carriage includes a pivot mechanism that enables rotational movement and a locking mechanism that secures the door in sliding position, eliminating the need for separate complex hinging systems for each function
5Adaptability or versatility
If multiple panels are used to provide flexibility with various configurations, then adaptability is improved, but ease of operation is reduced due to requiring multiple sliding and lifting motions
Solution Approach 1:
The door system uses two door panels that can be independently operated along the track. Each door can be slid or swung separately, allowing flexible configurations while maintaining simple operation. The segmentation of functions between two simple doors provides the same versatility as complex multi-panel systems but with easier operation

AI summary
A door assembly is provided for which can alternate between a pivoting and a sliding configuration. The door assembly can include a door panel, a track, a first carriage assembly, a second carriage assembly, and a locking mechanism. The first and second carriage assembly can connect the door panel to the track. The first and second carriage assemblies can be slidably movable on the track, and the first carriage assembly can further include a pivot mechanism that pivotably couples the door to the track. The locking mechanism can configure the door between the sliding and pivoting configurations. For example, the locking mechanism can mechanically couple the door panel to the second carriage assembly in the sliding configuration and mechanically decouple the door from the second carriage assembly in the pivoting configuration.
