Sliding Guide Hinge Pin Segmentation for Window Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding guides for windows and doors require complex installation, visible decoupling mechanisms, and long hinge pins that necessitate severe bending and multiple internal components, which complicate assembly and security.
Innovation Solution
A sliding guide design where the hinge pin is preassembled with the slider as a unit and detachably connected to the deployment arm, allowing for a shorter pin and easier assembly, with a coverable mechanism to conceal the coupling point, using a one-piece plastic slider with a central seat for the pin and a bolt with a secure insertion mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long hinge pin is used to connect the deployment arm to the sliding piece, then the connection is secure, but the deployment arm must be severely bent downwards and the installation becomes complex
Solution Approach 1:
The hinge pin is divided into two separate parts: a first part integrated with the deployment arm and a second part integrated with the sliding piece. This segmentation allows each part to be shorter and simpler, eliminating the need for severe bending of the deployment arm while maintaining secure connection through the complementary engagement of the two parts
Solution Approach 2:
The first part of the hinge pin is pre-integrated with the deployment arm during manufacturing, and the second part is pre-integrated with the sliding piece. This preliminary action eliminates the need for complex field assembly and severe bending operations, as the parts are designed to connect directly in their final positions
2Reliability
If multiple internal components are used to lock the hinge pin to the sliding piece, then the connection is secure, but the installation becomes complex and requires multiple steps
Solution Approach 1:
The locking function is merged into the geometric design of the hinge pin parts themselves. The first part features a head with a diameter larger than the longitudinal groove width, and the second part features a corresponding recess, creating an automatic lock through their complementary shapes without requiring separate locking components
Solution Approach 2:
The locking mechanism is extracted from separate internal components and integrated directly into the hinge pin structure. The head and recess formation of the hinge pin parts inherently provide the locking function, eliminating the need for additional locking elements and simplifying the overall assembly
3Strength
If the hinge pin is permanently connected to the deployment arm (e.g., riveted), then the connection is strong, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The hinge pin is segmented into two parts that are separately manufactured and then simply inserted into their respective components (deployment arm and sliding piece). This segmentation eliminates the need for time-consuming permanent connection processes like riveting, while the head-recess geometry provides sufficient connection strength
Solution Approach 2:
The hinge pin parts are pre-formed with their head and recess features during manufacturing, allowing for quick insertion and connection during assembly. This preliminary action eliminates the need for time-consuming field operations like riveting or welding
4Ease of operation
If the triggering mechanism is visible from the outside when the wing is in tilted position, then the operation is transparent, but security is compromised against unauthorized persons
Solution Approach 1:
The triggering mechanism is extracted from the visible exterior and relocated to the interior of the cover. The triggering element is integrated with the sliding piece inside the cover, making it invisible from the outside while maintaining full operational functionality through the cover's opening and closing movements

AI summary
The sliding guide has a raising arm (8) hinged to a sliding leaf of a window or door, where the raising arm is provided at an upper side of the sliding guide. The raising arm exhibits a pivot bolt (2) at its free end. A sliding piece (4) exhibits an opening at one of its longitudinal sides, where the opening is assessed and shaped in such a manner that a head region (2a) of the pivot bolt is laterally inserted into the opening before the sliding piece with the inserted pivot bolt is inserted into an inner duct of a hollow guide rail.
