Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If known closing devices for coverings are used, then the slats can be arranged to close or cover a ceiling or upper portion of a building, but the elements for orienting the slats are not sufficiently precise and reliable
Solution Approach 1:
The device segments the orientation control into two independent components: a fixed side guide element and a movable rotation member. This segmentation allows each component to perform its specific function optimally - the side guide provides stable reference while the rotation member enables precise angular adjustment of each slat element independently.
Solution Approach 2:
The rotation member acts as an intermediary between the fixed side guide element and the slat element. It translates the positional reference from the side guide into precise rotational orientation of the slat, mediating the orientation control function and improving both precision and reliability.
2Ease of operation
If known closing devices are used, then the slats can be moved between opened and closed conditions, but they exhibit irregularities in the opening and closing motion
Solution Approach 1:
The invention extracts the orientation control function from the translation mechanism by introducing separate side guide elements and rotation members. This separation eliminates the coupling between translational and rotational motions that causes irregularities in known devices, allowing each motion type to proceed smoothly and independently.
3Adaptability or versatility
If the device allows adjustment of slat inclination in closed condition, then light intensity can be modulated, but the device complexity increases
Solution Approach 1:
The invention merges the orientation adjustment function into the existing translation mechanism by using the side guide elements as fixed references and the rotation members as integrated adjustment components. This integration achieves light modulation capability without proportionally increasing device complexity, as the rotation members utilize the same structural framework as the translation system.

AI summary
An openable sunscreen device with adjustable slats comprises a plurality of slat elements (3) moved by at least one distance adjustment member (21) between opened (O) and closed (C) conditions. Each of the slat elements (3) has a respective longitudinal axle (9) whose ends (11) longitudinally slide along respective first site for sliding (15) of side guide element (17). Each slat element (3) has at least one respective inclined arm element (23) provided with a slider element (25). Said device (1) comprises at least one rotation member (27) for the rotation, in the closed condition (C), of each slat element (3), around its own axle (9). Such rotation member (27) comprises a longitudinal track element (31) parallel to said first lateral site for sliding (15) and, for each slat element (3), a corresponding transversal track element (33). The transversal track elements (33) are mutually parallel and inclined with respect to the longitudinal track elements (31) and placed at mutual distances equal to the maximum distance value in the closed condition (C) between said axes (9). Each transversal track element (33) intersects the longitudinal track element (31) at a respective switch element (35) provided with a corresponding swivelling track element (37) rotatable between a rotating condition in which it (37) is aligned with the respective transversal track element (33) and a sliding condition in which it (37) is aligned with the longitudinal track element (31). The device further comprises translation actuator members (41) of the rotation member (27) for moving it parallel to the longitudinal track element (31) and swivel actuator members (43) to rotate the swivelling track elements (37) in synchrony between the rotating and sliding conditions.
