Composite Shaft Spring Bolt Lock for Sectional Door Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sectional door entrance systems face issues with unstable and insecure closure due to backlash in articulations, limited adaptability to different dimensions, and aesthetically unpleasing bulkiness, along with difficulties in re-closure and forced exterior opening.
Innovation Solution
A closure system featuring a composite shaft mechanism with vertically movable shaft segments and spring bolts, allowing secure alignment and locking of multiple panels, adaptable to various heights and orientations, with a compact design and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single lock blocks only one panel of the entrance door, then the lock mechanism is simple, but the closure stability is insufficient due to backlash in articulations
Solution Approach 1:
The closure system is divided into multiple independent blocking means, each associated with a specific panel of the entrance door. Each blocking means can independently secure its corresponding panel, eliminating the cumulative backlash problem that occurs when panels are restrained only through repeated articulations from a single locked panel.
2Stability of the object's composition
If multiple latches are added to block multiple panels, then the closure stability improves, but the device complexity and bulk increase
Solution Approach 1:
Multiple blocking means are merged into a single integrated closure system that can be actuated by one lock mechanism. The blocking means are arranged along the edge of the door and can be simultaneously engaged or disengaged, providing multi-panel security without requiring separate control mechanisms for each panel.
Solution Approach 2:
The closure system is designed to be adaptable to different door configurations through adjustable positioning of the blocking means. The system can accommodate entrance doors of various heights and panel arrangements, making it a universal solution that doesn't require custom design for each specific door dimension.
3Manufacturing precision
If the closure system is designed for specific door dimensions, then the fit is precise, but the adaptability to different dimensions is reduced
Solution Approach 1:
The closure system incorporates adjustable elements that allow the blocking means to be repositioned along the door edge to match different panel heights and configurations. This dynamic adjustability enables the same closure system to be precisely fitted to various door dimensions without requiring custom manufacturing for each size.
4Device complexity
If the closure system requires specific manoeuvres for re-closure, then the opening mechanism can be simple, but the ease of operation is reduced
Solution Approach 1:
The closure system is designed to automatically return to the closed position after opening. When the door is opened and then released, the blocking means automatically engage with the stop blocks upon closing, eliminating the need for manual re-closure maneuvers. The system self-secures itself through the natural closing motion of the door.
