Sliding Pivoting Door Locking System Hermeticity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding-pivoting door systems are not adequately resistant to impacts, sabotage, and extreme weather conditions, and suffer from gaps that allow water and air infiltration, due to the use of perpendicular leverage parts and lack of uniformity in panel design.
Innovation Solution
A locking system with 'U' shape aluminium profiles that allow for adjustable locking and unlocking mechanisms, eliminating perpendicular leverage parts and ensuring all panels align closely, using half-moon shaped pivot parts and an array of slots to restrict longitudinal movement and enhance hermeticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If perpendicular leverage parts are used to enable pivoting movement, then the pivoting operation can be achieved, but the system becomes vulnerable to impacts, sabotage, and extreme weather conditions
Solution Approach 1:
The patent removes the perpendicular leverage part that protrudes from the sliding system plane, extracting the vulnerable element while maintaining the pivoting function through an alternative mechanism using slots and inverted T-shaped parts that are integrated into the panel structure
Solution Approach 2:
The locking system uses a composite structure combining aluminium profiles with glass panels, where the aluminium components provide structural strength and resistance to impacts, while the glass provides the required transparency and aesthetic properties
2Ease of operation
If panels are designed with gaps for pivoting movement, then the pivoting operation is enabled, but water and air infiltration occurs reducing hermeticity
Solution Approach 1:
The locking mechanism is designed to push all panels together in a longitudinal way before the pivoting operation, preliminarily closing any gaps between panels to prevent water and air infiltration during the pivoting movement
Solution Approach 2:
The patent uses an inverted T-shaped part with slots that allows movement in one dimension (transversal pivoting) while restricting movement in another dimension (longitudinal separation), enabling pivoting while maintaining panel alignment and hermeticity
3Object-affected harmful factors
If all panels are pushed together in longitudinal way to improve hermeticity, then water and air infiltration is stopped, but the pivoting operation may be restricted
Solution Approach 1:
The locking system is segmented into independent locking points for each panel, allowing individual panels to be locked in place while maintaining the ability to pivot, with the U-shaped profiles providing both longitudinal compression and rotational freedom
Solution Approach 2:
The system allows dynamic change in the distance between U-shaped profiles, compressing panels together for hermeticity during closed position, and allowing separation for pivoting operation, changing the physical parameters of the locking mechanism based on operational requirements

AI summary
Locking system for sliding-pivoting doors/panels (18 and 19) composed of: a guiding mechanism of the panels (18 and 19) placed in the sliding top track (21) and composed of a cap (8), an array of slots (9) and a guiding inverted "T" which complements the array of slots (9) which can be replaced by a protusion (25) of the top pivot part (24). A locking and unlocking mechanism of the panels (18 and 19) composed of a "U" shape profile (1) fixed to the wall, "U" shape moving profile (4) a pair of elbow shape parts (2), a handle (3), two blocks (5) and two plates (6) being the width of the base (23) of the profile (1) slightly bigger than the base (22) of the moving profile (4) and fitting the "U" moving profile (4) into the profile (1).
