Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lateral curtains are used for solar adjustment, then light control flexibility is improved, but components collide and entangle reducing durability
Solution Approach 1:
The patent transitions from horizontal lateral curtain movement to vertical curtain movement along rails. This dimensional change eliminates the collision and entanglement problems that occur when multiple lateral curtains operate simultaneously, while maintaining the ability to control light at different heights and angles.
Solution Approach 2:
The system divides the window area into multiple sections with independent vertical curtains controlled by separate driving modules. Each curtain operates independently on its own rail, preventing interference between components while providing flexible light control for different zones.
2Ease of manufacture
If lateral curtains move horizontally for solar adjustment, then installation simplicity is improved, but tracking accuracy of sunlight angle deteriorates
Solution Approach 1:
The system employs dynamically adjustable vertical curtains that can move up and down along vertical rails, allowing real-time adaptation to changing sunlight angles throughout the day. The independent control of multiple curtain sections enables precise tracking of solar position while maintaining relatively simple rail-based installation.

AI summary
A solar adjustment apparatus includes a control circuit, two optical encoders, two driving modules, and a power circuit. The control circuit is arranged in an upper rail, and the upper rail is fixed on the upper side of a door or window of a building or vehicle. The two driving modules pivot two spools at the same speed. One of the driving modules controls a height of a middle rail in vertical direction of the door or window through one of optical encoders and one of spools. The other driving module controls a height of a lower rail in vertical direction of the door or window through the other optical encoder and the other spool.
