Dual-Receiving Space Curtain Box for Glare and Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter and external venetian blind curtain boxes either allow glare or restrict heating from sunlight, and existing solutions for internal blinds are not visually appealing and impair window functionality.
Innovation Solution
A dual-receiving space curtain box design that accommodates both roller shutters/venetian blinds and roller blinds, with the second space for the roller blind positioned on the room side to allow optional sunlight passage, and a closure cover for flexibility, ensuring thermal insulation and glare protection without overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a roller shutter or external venetian blind is closed to provide glare protection, then glare protection is improved, but solar heating of the room is prevented
Solution Approach 1:
The shading system is segmented into two independent components: an external roller shutter/venetian blind for glare protection and an internal roller blind for heat control. This segmentation allows each component to perform its specific function independently, resolving the contradiction between glare protection and solar heating.
Solution Approach 2:
The internal roller blind acts as an intermediary element between the external shading system and the window glass. It provides a second stage of control that can selectively block heat while allowing visible light to pass through, mediating between the conflicting requirements of glare protection and solar heating.
2Illumination intensity
If an internal roller blind is attached to the ceiling, wall or window frame, then glare protection is improved, but the functioning of the window or door is impaired
Solution Approach 1:
The internal roller blind is extracted from traditional attachment points (ceiling, wall, window frame) and repositioned to attach to the external roller shutter box instead. This extraction from the window assembly preserves window functionality while maintaining glare protection capabilities.
Solution Approach 2:
Instead of attaching the roller blind directly to the building structure, the patent uses the external roller shutter box as a surrogate attachment point. This copying of the external box's mounting function allows the internal blind to be supported without interfering with window operation.
3Volume of stationary object
If the second receiving space is positioned close to the window, then space utilization is improved, but overheating of the space between window and blind occurs
Solution Approach 1:
The patent applies different spatial requirements to different functional zones: the first receiving space (external blind) is positioned optimally for its shading function, while the second receiving space (internal blind) is positioned at a specific distance from the window to prevent overheating. This local quality adjustment resolves the contradiction between space utilization and thermal comfort.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables glare protection and controlled heating by allowing sunlight to pass through on sunny days while maintaining thermal insulation and visual appeal, with the option to add a roller blind later.
Implementation Method 1
The box can, for example, terminate essentially flush on the outside with the masonry or the composite thermal insulation system

AI summary
The roller shutter- or venetian blind hanging cabinet has a receiving space (9) for receiving a roller shutter (2) or venetian blind hanging. Another receiving space (10) is provided for receiving a roller (3). The former and the latter receiving spaces are connected with openings (6,7) that are arranged at the lower side of the cabinet.
