Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation assemblies for windows are customized and expensive to produce due to a lack of standardization, leading to limited cost efficiency when only the ventilation functionality is required.
Innovation Solution
A cost-effective ventilation assembly design featuring a casing with a connection member and actuator slide, where the actuator slide is connected to operating means for movement between closed and ventilation positions, utilizing a wire spring for bi-stable positioning and a compact construction with fewer manufacturing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ventilation assembly with multiple components (locking arm, lock mechanism, actuator slide, slot) is implemented as part of the opening mechanism, then the ventilation functionality is achieved, but the manufacturing cost increases due to numerous parts
Solution Approach 1:
The patent extracts the ventilation mechanism from the opening mechanism, creating a separate, standalone ventilation assembly. This allows the ventilation function to be achieved independently without requiring the full opening mechanism components, thereby reducing the number of parts while maintaining ventilation reliability
Solution Approach 2:
The ventilation assembly is designed as a universal component that can be integrated into different window types without requiring customization. The standardized design with essential components (casing, connection member, actuator slide, guiding means) provides multi-functional capability across various window applications, reducing manufacturing complexity
2Adaptability or versatility
If ventilation assemblies are customized to each different type of window, then the ventilation functionality is optimized for specific windows, but the production cost increases due to lack of standardization
Solution Approach 1:
The ventilation assembly employs a universal design with standardized components including a casing with guiding means, a connection member with fixation member, and an actuator slide. This standardized configuration can be adapted to different window types without requiring custom manufacturing, thereby optimizing production costs while maintaining versatility
Solution Approach 2:
The connection member is designed with a pivotable connection at the first connection point and a movable connection at the second connection point (through the oblong hole). This dynamic design allows the same component to adapt to different window configurations and operational requirements, providing versatility without customization

AI summary
A ventilation assembly (1; 1002) for a ventilating window having a sash, comprising a casing (2; 1002) fixed to the sash, wherein the casing (2; 1002) comprises a ventilation mechanism (3; 1003) arranged in the casing (2; 1002), which comprises a connection member (4a, 4b; 1004a, 1004b) having a first connection point (6a, 6b; 1006a, 1006b) and a second connection point (8a, 8b; 1008a, 1008b), where the second connection point (8a, 8b; 1008a, 1008b) is connected to an actuator slide (5, 1500) for enabling the connection member (4a, 4b; 1004a, 1004b) in the casing (2; 1002) to be displaced between a first position, defining a closed position, and a second position, defining a ventilation position. The displacement is achieved by means of the actuator slide (5; 1500) which is displaceable in guiding means (9; 1009) in the casing (2; 1002) wherein the actuator slide (5; 1500) is connected to operating means (502; 1502) for enabling movement of said actuator slide (5; 1500) between the first position and the second position, defining an open and closed ventilation position, respectively.
