Solution Overview
Problem
Existing sun protection installations with moving blades require complex mechanisms for reliable operation, prone to blockages and damage due to play and connections between elements, making the displacement system delicate and difficult to maintain.
Innovation Solution
A sun protection installation with a load-bearing frame and darkening slats, featuring a rail and guide system, carriages with hooking elements for translation, and a device for transmitting rotary movement, along with connecting elements to maintain constant distances between slats, allowing for simultaneous deployment and rotation of blades with a simplified drive system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex mechanism is used to enable both deployment and rotation of blades, then the functionality is improved, but the device complexity increases and reliability decreases
Solution Approach 1:
The patent merges the deployment function and rotation function into a single integrated mechanism. The guide rod simultaneously performs both functions: when it translates along its axis, it deploys the blade; when it rotates around its axis, it rotates the blade. This eliminates the need for separate mechanisms for each function, reducing overall device complexity while maintaining full functionality.
Solution Approach 2:
The guide rod is designed as a multi-functional component that performs multiple operations. It serves as both a translational guide for blade deployment and a rotational guide for blade orientation. This universal component approach reduces the number of parts needed and simplifies the overall mechanism structure.
2Ease of operation
If a complex mechanism with multiple connections is used for blade movement, then the displacement capability is improved, but the reliability decreases due to play and connections leading to blockages or damage
Solution Approach 1:
The patent combines multiple connection functions into a single guide rod-blade interface. Instead of having separate connections for deployment and rotation, the guide rod provides both functions through its geometric design. This reduces the number of connection points and potential failure locations, improving reliability while maintaining full displacement capability.
Solution Approach 2:
Instead of using multiple separate components to achieve deployment and rotation, the patent inverts the approach by using a single component (guide rod) whose geometric constraints naturally produce both motions. The guide rod's orientation and connection points are designed so that its movement automatically generates the desired blade deployment and rotation without requiring additional complex connections.
3Measurement precision
If individual drive systems are used for each carriage, then the control precision is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple individual drive systems into a single drive mechanism that controls all carriages simultaneously. The connecting elements link the carriages together, so that one drive unit can move multiple carriages in a coordinated manner. This maintains control precision through the mechanical coupling while dramatically reducing the number of drive components needed.
Solution Approach 2:
The patent segments the drive function by using connecting elements that distribute the drive force from a single source to multiple carriages. Each carriage is independently positionable through this segmented approach, maintaining control precision while simplifying the overall drive system architecture.
