Gearmotor Anchoring System With Guide Elements For Roller Shutters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gearmotors for roller shutters are heavy, requiring at least two installers to handle and install them safely, often leading to unsafe and unstable temporary fixes due to their weight and difficult access positions.
Innovation Solution
A gearmotor anchoring system with a guide mechanism that allows easy alignment and coupling of semi-cylindrical elements, enabling a single installer to securely fasten the gearmotor to a spring-holder shaft without complex alignment of holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gearmotor is secured using traditional bolt-and-hole alignment method, then high tightening forces and stability are achieved, but installation complexity increases and requires at least two installers
Solution Approach 1:
The patent introduces guide elements as intermediary components that mediate between the two semi-cylindrical elements during assembly. These guide elements temporarily constrain the relative positioning, enabling easy alignment of holes without requiring precise manual alignment by multiple installers. After the connecting members are inserted, the guide elements are removed, and the final stable connection is achieved through the bolts.
2Ease of operation
If gearmotor weight is reduced, then ease of installation by single installer is improved, but lifting capacity and structural strength are compromised
Solution Approach 1:
The patent divides the anchoring system into two separate semi-cylindrical elements that are assembled around the spring-holder shaft. This segmentation allows each element to be handled more easily by a single installer, yet when combined and secured with connecting members, they provide the necessary strength and stability to support heavy roller shutters weighing up to 100 kilograms.
3Productivity
If unsafe temporary fixing methods are used, then installation speed is improved, but safety and stability are compromised
Solution Approach 1:
The patent incorporates guide elements that are pre-positioned on the semi-cylindrical elements before assembly. These guide elements perform the preliminary action of aligning the holes and constraining the relative positioning during assembly, eliminating the need for unsafe temporary fixing methods. This preliminary alignment action enables both safe and efficient installation by a single installer.

AI summary
Gearmotor safe anchoring system for roller shutters comprising an upper hollow semi-cylindrical element (100) which is coupled to a lower hollow semi-cylindrical element (200) and tightened around a spring-holder shaft (300) by means of common bolts (400) inserted in four through-holes (240) obtained on four housing seats (250) made laterally to said lower hollow semi-cylindrical element (200) and screwed into four threaded holes (140) obtained on four housing seats (150) made laterally to the upper hollow semi-cylindrical element (100) and in which on each housing seat of the four through-holes (240) there is a guide element (500) which engages and creates a constraint with longitudinal sliding and receives the housing seats (150).
