Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutters with slats that allow air and light passage are costly due to the need for additional mosquito net accessories and complex assembly processes.
Innovation Solution
A roller shutter design with modular slats featuring integrated slots forming a lattice mosquito net and doors that open under the weight of adjacent slats, eliminating the need for separate mosquito nets and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate mosquito net accessories are added to block insects, then insect barrier function is improved, but device complexity and production cost increase
Solution Approach 1:
The patent merges the mosquito net function with the frame structure by creating slots directly in the frame wall that form a lattice pattern. This integration eliminates the need for separate mosquito net accessories, reducing device complexity while maintaining insect barrier functionality. The slots are formed as integral parts of the frame during manufacturing, combining multiple functions into a single component.
Solution Approach 2:
The frame structure is designed to serve multiple functions simultaneously: it provides structural support, creates slots for light and air passage, and forms an integrated lattice that acts as a mosquito net. This multi-functionality reduces the number of separate components needed, simplifying the overall device while maintaining all required functions including insect protection.
2Object-affected harmful factors
If separate mosquito net accessories are added to block insects, then insect barrier function is improved, but production cost increases
Solution Approach 1:
By integrating the mosquito net function directly into the frame through slot formation, the patent eliminates the need to manufacture and assemble separate mosquito net accessories. This reduces production steps, material costs, and assembly operations, thereby lowering overall production cost while maintaining effective insect barrier functionality.
Solution Approach 2:
The frame is designed as a multi-functional component that simultaneously provides structural support, enables light and air passage through slots, and creates an integrated mosquito net lattice. This consolidation reduces the total number of parts that need to be manufactured and assembled, leading to lower production costs and improved manufacturing efficiency.
3Object-affected harmful factors
If complex assembly processes are used to add mosquito nets, then insect barrier function is improved, but assembly time increases
Solution Approach 1:
The patent integrates the mosquito net function directly into the frame structure through slot formation, eliminating the need for separate assembly steps to install mosquito net accessories. The slots are formed as integral parts of the frame during manufacturing, so no additional assembly operations are required, reducing assembly time to zero for this function.
Solution Approach 2:
The frame structure is designed to perform multiple functions including structural support, light passage, air passage, and insect protection through its integrated slot lattice. This multi-functionality is achieved through a single manufacturing process, eliminating the need for multiple assembly steps and significantly reducing assembly time while maintaining all required functions.

AI summary
A roller shutter intended to occlude a passage, said shutter comprising: i) a plurality of slats (2) side by side and intended to occlude the passage (60); said plurality of slats (2) comprising a first and a second adjacent slat (3, 4); ii) guide means (6) for guiding the slats (2) along a path that allows to pass from a configuration in which the shutter (1) occludes the passage (60) to a configuration in which the shutter (1) frees said passage (60) and vice versa; said first slat (3) comprising: -a frame (31) comprising a wall (310) defining and crossed by a plurality of slots (32) for the passage of light and/or air; -a door (33) constrained to said frame (31) and movable between a closing configuration in which it overlaps said slots (32) and an opening configuration in which it allows air and/or light to pass through the thickness of the first slat (3). The door (33) comprises: first gripping means (34) for rotatably constraining to a lower part (40) of the second slat (4); and - second gripping means (35) for rotatably constraining to the frame (31); said second rod (4) acting as a lever for opening the door (33). The slots (32) are arranged to form a lattice and define in combination a mosquito net.
