Folding Door Locking Post Segmentation and Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking posts for folding doors are expensive to construct and difficult to mount and service, with protruding components that can be damaged or mar the appearance of the door.
Innovation Solution
A locking post constructed from separate face and end panels with spaced-apart spacers, allowing for easy installation and servicing of lock mechanisms, with the panels forming a tubular enclosure and providing a recess for lock components to protect them from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a unitary tubular construction is used for the locking post, then the structural strength and integrity are improved, but the difficulty of mounting and servicing lock mechanisms increases
Solution Approach 1:
The locking post is divided into separate modular components: face panels, end panels, and spacers that can be assembled and disassembled independently. This segmentation allows lock mechanisms to be easily mounted and serviced by removing end panels, while the overall structural integrity is maintained through the coordinated assembly of these components.
2Ease of manufacture
If a unitary tubular construction is used for the locking post, then the manufacturing simplicity is improved, but the construction cost increases
Solution Approach 1:
The post is constructed from separate face panels, end panels, and spacers that can be manufactured independently using simpler processes, then assembled together. This reduces the complexity of manufacturing each individual component while the overall assembly provides the complete locking post structure.
Solution Approach 2:
The spacers are positioned between the face panels and secured within the assembly formed by the panels, creating a nested structure where components fit within and support each other. This nested arrangement simplifies manufacturing of individual parts while achieving the complete structural function.
3Ease of operation
If lock mechanisms are mounted on the post surface, then the ease of operation is improved, but the vulnerability to damage and appearance maring increases
Solution Approach 1:
The lock mechanisms are extracted from the external surface and mounted on the spacers within the protected space created by the face and end panels. This extraction removes the vulnerable components from direct exposure to damage while maintaining their operational accessibility through the panel structure.
Solution Approach 2:
The lock mechanisms are nested within the protective enclosure formed by the face panels and end panels, mounted on the spacers. This nested positioning protects the lock components from external damage and appearance degradation while preserving their functionality.

AI summary
A locking post for a folding door having two face panels and two end panels, the panels extending the length of the post. A plurality of relatively short, spacers are in the post, including a spacer at each end of the post. First fasteners fasten one face panel to each spacer on one side of each spacer and fasten the other face panel to each spacer on the side of each spacer opposite the one side, the face panels parallel and aligned. Second fastens detachably fasten one end panel to both face panels along one side of the face panels and detachably fasten the other end panel to both face panels on the other side of the face panels, the end panels parallel, the face panels and end panels together providing a tubular enclosure for the spacers.
