Roller Shutter End Closure Pre-Assembly Sliding Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing devices for closing the end of a roller shutter box are inefficient in terms of mounting productivity, as they require separate assembly and disassembly of cheek and heel components, which complicates the process and reduces efficiency.
Innovation Solution
The device comprises permanently assembled reciprocal members, including openings and protrusions on the cheek and heel, allowing for sliding assembly and preventing inadvertent disassembly, enabling the cheek and heel to be pre-assembled and stored as an integral unit, facilitating easier installation on the roller shutter box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cheek and heel are separate components requiring separate assembly, then the device allows for flexible positioning and installation, but the mounting productivity is reduced due to complex multi-step assembly processes
Solution Approach 1:
The patent merges the cheek and heel into a single integrated component called the 'end closure assembly'. The cheek portion and heel portion are permanently assembled together through reciprocal assembly members (protrusions fitting into recesses), eliminating the need for separate assembly operations. This single integrated assembly is installed as one unit, directly improving mounting productivity while maintaining all functional benefits of having both cheek and heel features.
2Loss of time
If the cheek and heel are assembled separately during installation, then the components can be independently manufactured and stored, but the installation time and process complexity increase
Solution Approach 1:
The cheek and heel are pre-assembled into an integrated end closure assembly during manufacturing, before installation at the installation site. The reciprocal assembly members are permanently connected, so that when the assembly is installed, it is installed as a complete unit. This preliminary assembly action eliminates the need for on-site assembly operations, reducing installation time and simplifying the installation process to a single placement operation.
3Adaptability or versatility
If multiple separate components are used for the end closure, then the device can accommodate various mechanisms and motors, but the number of parts increases leading to longer assembly procedures
Solution Approach 1:
The integrated end closure assembly combines multiple functions into a single component. The cheek portion provides positioning and support functions, while the heel portion provides sealing and blocking functions. By permanently assembling these together, the single end closure assembly can accommodate various mechanisms and motors (maintaining versatility) while being installed as one unit (improving mounting speed and productivity).

AI summary
The device (6) has a flange (7) comprising an anchoring member (7a) in a part of a case of a rolling shutter. A lug (8) has anchoring members (8a) in the part and blocking members of the flange relative to the part along a longitudinal direction (H). The lug is placed on the part by a sliding movement along the direction from a reverse position to a forward position. The flange and the lug include reciprocal assembling members e.g. opening (12), and an excrescence such that the flange and the lug constitute an assembly formed, stored, provided and placed on the part of the case. An independent claim is also included for a method for mounting a case of a rolling shutter.
