Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic mechanisms are used to generate tilting movement of strips, then the strips can be tilted and positioned, but substantial current intensity is required and thick cables are necessary
Solution Approach 1:
The patent replaces magnetic mechanisms with electrostatic mechanisms. Instead of using magnets that require substantial current intensity, the invention uses electrostatic attraction between oppositely charged electrodes and strips to achieve tilting movement. This substitution dramatically reduces the electrical current required while maintaining the ability to position and tilt strips effectively.
Solution Approach 2:
The patent changes the fundamental physical parameter from magnetic field strength to electrostatic potential difference. By using high voltage at low current, the system achieves the same mechanical effect (strip tilting) with much lower power consumption and without requiring thick cables for current transmission.
2Ease of operation
If mechanical constructions are used for strip regulation, then the strips can be positioned, but the constructions become complex and are unsuitable for large-scale use
Solution Approach 1:
The patent replaces complex mechanical constructions with a simplified electrostatic system. Instead of mechanical linkages, gears, or motors, the invention uses electrostatic attraction between electrodes and strips to achieve positioning. This eliminates complex mechanical components while maintaining precise strip control capability.
Solution Approach 2:
The patent transitions from mechanical parameter control (physical linkages, motor positions) to electrical parameter control (voltage application to electrodes). This parameter change simplifies the overall construction while enabling sophisticated strip positioning through electronic control of electrostatic fields.
3Ease of operation
If magnets are used for tilting movement, then the strips can be moved, but operational safety is limited
Solution Approach 1:
The patent replaces magnetic actuation with electrostatic actuation. The electrostatic mechanism inherently provides better operational safety because it uses high voltage at very low current, eliminating the risks associated with high-current magnetic systems. The strips are attracted to electrodes through electrostatic forces without requiring continuous power or complex control mechanisms.
Solution Approach 2:
The patent employs periodic or pulsed voltage application to electrodes to control strip positioning. By applying voltage only when needed to move or hold strips in specific positions, and allowing electrostatic attraction to maintain position without continuous power, the system achieves safe and reliable operation with minimal energy consumption and reduced operational risks.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a simple, energy-efficient, and safe means to control light transmission, enabling flexible light regulation with minimal energy consumption and easy installation, suitable for large-scale applications beyond greenhouses.
Implementation Method 1
displacement of the strips is controlled electrostatically. Providing the strips or a portion thereof with a polarity and providing the further electrodes with the same or, conversely, a different polarity will cause the strips of the further electrodes to move away from or toward said strips respectively
Implementation Method 2
a simple low-voltage activator allows, a simple power source which may or may not be present on site, a high potential difference to be generated, as a result of which the strips can move into a different position
Implementation Method 3
power can be transmitted wirelessly with induction. This induction can comprise both the low-voltage part and the high-voltage part

AI summary
Strip assembly consisting of a number of strips which are hingeably attached in order to influence or not to influence light. Strips can be displaced between two positions by static charging/discharging with respect to a support attached in proximity to the strip. A voltage source is present to provide the strips/further electrodes with the respective voltage. The strips can be configured to be (partially) non-transparent, allowing all manner of light effects to be obtained. In addition, it is possible to configure various strips differently. The strips preferably consist of a foil material so an especially simple construction may be realized with the aid of a film hinge. Suitable materials include polycarbonate, polyester or plastics material based on aromatics. The surface resistance is preferably at most 1000 MO. A broad range of uses are possible. One use is that in greenhouses but the present invention can also be applied at other locations where protection from light is necessary or specific light effects are desired.
