Roller Blind Drive Box With Tulip-Integrated Battery Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutters with autonomous motorization face issues with battery recharging accessibility, particularly when installed on windows above ground level, leading to mechanical weakening and increased installation complexity due to the need for a connection box that alters the box's structure.
Innovation Solution
A box design with tulips integrating electric cables and connectors for battery recharging, allowing easy access without mechanically weakening the structure, featuring a guide chute with a recess and removable hatch for connection to an external charger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connection box is implemented to access battery power cables, then battery recharging accessibility is improved, but the box structure is mechanically weakened and production time increases
Solution Approach 1:
The invention extracts the cable access function from the main box structure by creating a dedicated opening in the rear face. This allows cable connection without requiring a separate connection box that would weaken the overall structure. The opening is strategically positioned and sized to provide access to the battery connector while maintaining the structural integrity of the box.
Solution Approach 2:
The invention segments the cable access function from the main box body by creating a distinct opening area. This segmentation allows the main box structure to remain intact and strong while providing a dedicated access point for battery recharging. The opening is designed as a separate feature rather than modifying the entire box structure.
2Ease of operation
If a connection box is implemented to access battery power cables, then battery recharging accessibility is improved, but production time and installation complexity increase
Solution Approach 1:
The invention removes the need for a separate connection box by directly opening the rear face of the main box. This extraction of the cable access function from a separate component simplifies the overall device structure and reduces installation complexity. The opening is designed to be created during standard box fabrication, integrating cable access into the basic manufacturing process.
3Ease of operation
If the inspection hatch is opened from outside the building to access the battery, then battery recharging is possible, but it becomes problematic for roller shutters installed on upper floors
Solution Approach 1:
The invention extracts the cable access function from the inspection hatch location and positions it on the rear face of the box. This allows the battery connector to be accessed from the building interior side through the rear face opening, eliminating the need to open the inspection hatch from outside the building. The connector is positioned such that it can be reached through the opening in the rear face from inside the building.
