Shutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shutters and glass plates in buildings face challenges in preventing rainwater and insect infiltration while maintaining ventilation, and existing solutions like screen windows compromise aesthetics and functionality.
Innovation Solution
A shutter system with a window frame, movable blade structures, an intake driving unit, and an airflow guiding unit that allows for controlled ventilation and rain prevention without the need for a screen window or fan, utilizing through holes, outlets, and adjustable blade structures to manage airflow and rainwater.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If shutters or glass plates are tightly closed to prevent rainwater infiltration, then rainwater infiltration is prevented, but indoor ventilation is blocked and indoor temperature increases
Solution Approach 1:
The shutter blade is divided into multiple segments (first blade segment, second blade segment, third blade segment) that can rotate independently around a rotation axis. This segmentation allows different portions of the blade to perform different functions: blocking rainwater while simultaneously creating channels for air ventilation through the coordinated rotation of segments.
Solution Approach 2:
The shutter blade structure employs dynamic rotation of blade segments around a rotation axis, transforming the static closed state into a dynamic adjustable state. The blade segments can rotate to different positions to adapt to varying weather conditions, enabling the system to block rainwater when needed while maintaining ventilation channels when weather permits.
2Object-affected harmful factors
If screen window is installed to prevent insect infiltration, then insect infiltration is prevented, but building aesthetics are spoiled and screen window durability is reduced
Solution Approach 1:
The shutter blade segments can rotate dynamically to create insect-blocking configurations when needed, while returning to aesthetically pleasing positions when not in use. This dynamic capability eliminates the need for permanent screen windows that compromise building aesthetics, as the protective function is activated only when necessary.
Solution Approach 2:
The invention extracts the insect-blocking function from the permanent screen window structure and integrates it into the movable shutter blade system. This allows the insect protection function to be activated only when needed, rather than being a permanent fixture that continuously affects building aesthetics.
3Productivity
If shutters are open to allow ventilation, then indoor air quality is improved, but rainwater and insect infiltration occur
Solution Approach 1:
The segmented blade structure allows different portions to perform different functions simultaneously. When rotated to specific positions, the segments create ventilation channels for air flow while their arrangement and orientation block rainwater and insects from entering through the same opening.
Solution Approach 2:
Different portions of the shutter blade structure have different functional qualities: certain blade segment positions and orientations are optimized for ventilation while others are optimized for blocking rainwater and insects. The local configuration of blade segments can be adjusted to provide the appropriate quality for each specific requirement.

AI summary
A shutter includes a window frame, a plurality of blade structures, an intake driving unit and an airflow guiding unit. The window frame has an upper frame portion, a lower frame portion and two side frame portions. The blade structures are disposed on the window frame, and each has a through hole and a plurality of outlets. The intake driving unit is disposed in the upper frame portion. The airflow guiding unit is disposed in at least one of the two side frame portions. Each of the through holes of the blade structures communicates with the inside of at least one of the two side frame portions.
