Sliding Door Control Unit Quick-Fit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control and operating units for sliding doors or windows require complex and time-consuming installation processes, involving precise centring and fixing with striker plates, which can lead to inefficiencies and reduced durability, and also incur higher costs due to separate component storage for various door or window profiles.
Innovation Solution
The solution involves a mounting member with a spacer and flexible plug that allows quick and precise fitting by elastic deformation into the groove, enabling snap fastening and secure positioning, reducing the need for complex centring operations and enhancing mechanical durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If striker plates are used to fix the control and operating unit in the groove, then the unit can be secured to the sash upright, but the installation process becomes complex and time-consuming requiring precise centring operations
Solution Approach 1:
The mounting member is pre-assembled with the control box and operating rod inside the groove before insertion. This preliminary assembly eliminates the need for complex on-site centring operations with striker plates, significantly reducing installation time while maintaining secure fixation
Solution Approach 2:
The control box and operating rod are extracted from the mounting member for separate manufacturing, then pre-assembled together before final installation. This allows the mounting member to be prepared in advance with precise positioning, eliminating time-consuming centring operations during installation
2Manufacturing precision
If multiple striker plates are inserted and positioned one by one along the groove, then correct alignment can be achieved, but the operation requires considerable time and effort
Solution Approach 1:
Multiple positioning functions are merged into a single mounting member structure. The mounting member integrates the control box housing, operating rod guide, and positioning features into one component that is pre-assembled inside the groove, eliminating the need for multiple separate striker plates and their individual positioning operations
Solution Approach 2:
The mounting member is pre-assembled with all internal components (control box, operating rod) and positioning features before installation. This preliminary preparation ensures correct alignment is built-in, eliminating time-consuming on-site positioning operations
3Reliability
If the control box and operating rod are housed inside the groove with a front wall mounting member, then the unit can be fixed and centred, but warehouse costs increase due to separate storage of components for different profiles
Solution Approach 1:
The mounting member is designed as a universal component that can be adapted to different sash profiles through the groove structure. The control box and operating rod assembly fits within the standardized groove dimensions, allowing one mounting member design to serve multiple profile types, thereby reducing the need for separate component inventories for different door or window profiles
4Reliability
If striker plates are used to couple the mounting member to the groove, then the unit can be attached, but the mechanical durability of the coupling is low
Solution Approach 1:
The mounting member is segmented into distinct functional zones: a front wall portion for visibility and access, and an internal cavity for housing the control box and operating rod. This segmentation allows the mounting member to be optimally shaped for both mechanical durability in the groove coupling and functional requirements of the control mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach simplifies the installation process, ensures accurate alignment, and increases mechanical durability, making the control and operating unit easier to fit and maintain over time, while reducing overall costs and improving thermal insulation.
Implementation Method 1
a plug (22) for positioning and centring the mounting member (2) in the main groove (4), configured to be stably coupled to the spacer element (19) before being housed in the main groove (4), characterized in that the plug (22) has a pair of flexible wings (24, 25) which are configured to form a corresponding wall extending outwards from the plug (22) and in such a way as to vary, or reduce, the gap between them so as to allow the plug (22) to be inserted by elastic deformation into the channel (17) from the front

AI summary
A control and operating unit for sliding doors or windows comprises: a mounting member (2) which can be associated with the inside of the edge profile of a sash upright (3) defined by a main groove (4) delimited by two longitudinal walls (5, 6) of the upright (3); a control box (7) associated with the mounting member (2), equipped with a housing (8) for receiving the shaft (9) of a handle (10) and with a kinematic unit which transmits the movement imparted by the handle (10) and which is connected to an operating rod (11) positioned along and parallel to the mounting member (2) and movable in both directions relative to the selfsame mounting member (2); fastening means (14) by which the mounting member (2) is joined to the sash and which are configured to fix the mounting member (2) to the inside of the main groove (4) also by abutment against a pair of opposed flanges (15, 16) protruding transversely from the walls of the upright (3) and defining a secondary, inner channel (17) together with the bottom wall (18) of the main groove (4); these fastening means (14) by which the mounting member (2) is joined to the upright (3) comprise: a spacer element (19) associated with, and protruding from, the mounting member (2); a plug (22) for positioning and centring the mounting member (2) in the main groove (4), configured to be stably coupled to the spacer element (19) before being housed in the main groove (4); the plug (22) has a pair of wings (24, 25) which are flexible so that, in use, they can be inserted by elastic deformation into the secondary groove (17) from the front and so that at least part of the plug (22) can then be stably housed in the selfsame secondary channel (17).
