Sliding-Hinged Door Sash Pack for Full Opening Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding doors in boats do not effectively eliminate barriers between inner and outer spaces, limiting communication and integration of these areas.
Innovation Solution
A door system with a rotating sash pack formed by a hinged and sliding sashes, featuring automatic fastening devices and a control system that allows the sashes to rotate freely once disengaged from the rails, enabling complete clearance of the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a sliding door with multiple sashes is used, then the area for communication between inner and outer spaces is increased, but the device complexity increases due to multiple sashes and rails
Solution Approach 1:
The patent applies dynamics by enabling the sash pack to rotate about a vertical axis after being liberated from the rails, transforming the door from a static sliding mechanism to a dynamic system that can achieve complete opening clearance, thereby increasing communication area without permanent structural complexity
Solution Approach 2:
The door is segmented into a first sash mounted at a first upright and at least one second sash sliding along rails, allowing independent movement and configuration of different sash components to achieve the desired opening clearance and communication area
2Area of stationary object
If the door is designed to open completely to eliminate barriers, then the communication between spaces is enhanced, but the ease of operation decreases due to the complex mechanism of moving rails and automatic fastening
Solution Approach 1:
The automatic fastening device performs self-service by automatically fastening the second sash to the first sash when the second sash reaches the second position during sliding, eliminating the need for manual intervention in the fastening process and simplifying operation
Solution Approach 2:
The control system performs preliminary action by moving the rails with respect to the cross-pieces between forward and retracted positions in advance, preparing the system for the subsequent rotation of the sash pack and enabling complete opening without complex manual manipulation
3Reliability
If automatic fastening devices are added to secure the sash pack, then the reliability of the door system is improved, but the device complexity increases
Solution Approach 1:
The automatic fastening device is configured to automatically fasten the second sash to the first sash when the second sash reaches the second position during sliding, eliminating the need for manual fastening operations and improving reliability through automated securement
Solution Approach 2:
The fastening function is merged with the sliding mechanism, where the same movement that positions the second sash along the rails also triggers the automatic fastening to the first sash, combining multiple functions into a single integrated operation rather than adding separate complex fastening systems

AI summary
A door comprising a first sash (20) and at least a second sash (30, 40) slidable along rails (15, 16), at least one automatic fastening device (50) configured to automatically fasten the at least one second sash (30, 40) to the first sash (20) when the at least one second sash (30, 40) reaches an engagement position with a abutment part (22) of the first sash (20), and a control system (60) operable to move the rails (15, 16) relative to frame cross-pieces (13, 14), between a forward position in which the rails (15, 16) are able to engage the at least one second sash (30, 40), and a retracted position wherein the rails (15, 16) do not interfere with the at least one second sash (30, 40), allowing a sash pack (20-40) formed by the first sash (20) and by the at least one second sash (30, 40) fastened to the first sash (20) to rotate about a vertical axis (Y).
