Cover Plate Assembly for Winder Box with Snap-Coupled Segmented Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover plates for winder boxes in shutter systems are inadequate in terms of aesthetics, thermal and acoustic insulation, and safety, especially when manual winders are replaced with motorized systems.
Innovation Solution
A cover plate assembly that includes a sub-plate and a cover plate without through openings, designed for easy installation and removal, providing complete closure of the winder seat and ensuring safety and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If through openings are provided in the cover plate to allow passage of belts or chains, then the winder mechanism can function, but dust and humidity infiltration occurs and thermal and acoustic insulation is weakened
Solution Approach 1:
The cover plate is divided into two separate components: a sub-plate that remains fixed with belt openings for functionality, and a removable cover plate that provides closure. This segmentation allows each part to fulfill its specific function - the sub-plate enables belt passage while the cover plate blocks dust and humidity when installed.
Solution Approach 2:
The cover plate is designed to be removable and re-installable, transforming from a static closed structure to a dynamic system that can open for maintenance and close for protection. This dynamic capability allows the cover to adapt between providing insulation and allowing access to the winder mechanism.
2Ease of operation
If through openings are provided in the cover plate, then the winder mechanism can function, but thermal and acoustic insulation are weakened
Solution Approach 1:
The cover plate assembly separates the functional opening requirements from the insulation requirements by using two distinct plates. The sub-plate provides the necessary belt passage openings for operation, while the cover plate provides continuous coverage to maintain thermal and acoustic insulation when installed.
3Reliability
If the cover plate is designed to be permanently fixed, then safety is improved by eliminating gripping points, but ease of installation and removal is reduced
Solution Approach 1:
The cover plate assembly uses a sub-plate that is permanently fixed to the winder box for safety, while the cover plate itself remains removable. This segmentation allows the fixed portion to provide safety by eliminating gripping points, while the removable cover plate maintains ease of installation and removal for maintenance purposes.
4Shape
If the cover plate is made without through openings, then aesthetics and insulation are improved, but the winder mechanism cannot function
Solution Approach 1:
The cover plate assembly divides the functional requirements from the aesthetic requirements. The sub-plate contains the necessary belt openings for winder functionality, while the cover plate provides a clean, open-faced appearance without visible openings when installed, thus satisfying both aesthetic and functional requirements.

AI summary
A cover plate assembly (1) for a winder seat (21) of a winder box (2) for a winder of a shutter, comprises a sub-plate (10), suitable for being fastened to the winder seat (21) and comprising one or more sub-plate coupling portions (11, 12, 13). The assembly also comprises a cover plate (3), comprising a sub-plate seat (33) suitable for accommodating the sub-plate (10) therein when the cover plate (3) is coupled to the sub-plate (10). The assembly (1) is characterized in that the cover plate (3) is totally devoid of through openings and comprises plate coupling portions (30, 31, 32) suitable for being snap-coupled to the one or more respective sub-plate coupling portions (11, 12, 13) for releasably snap-coupling the cover plate to the sub-plate (10) and completely closing the winder seat (21).
