Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motor and pulleys are used for mechanical movement, then the windbreaker can be lifted automatically, but the cost increases due to motor, electrical installation and maintenance requirements
Solution Approach 1:
The patent employs a gas piston (pneumatic device) to provide the lifting force for the mobile pane. The gas piston converts compressed gas energy into mechanical motion, eliminating the need for motors and electrical systems while achieving automatic lifting. This directly addresses the contradiction by replacing complex electrical-mechanical systems with a simpler pneumatic system that requires no external power source or electrical installation.
Solution Approach 2:
The gas piston system is self-contained and does not require external power sources, control systems, or maintenance infrastructure. The compressed gas spring provides continuous lifting force without needing electrical installation, motors, or pulleys. This self-service characteristic eliminates the complexity associated with motor-driven systems while maintaining automatic lifting capability.
2Device complexity
If manual lifting is used, then the device structure is simpler, but it requires muscular power and is difficult to use
Solution Approach 1:
The gas piston provides mechanical assistance by storing and releasing compressed gas energy to lift the mobile pane. This pneumatic assistance eliminates the need for user muscular effort while maintaining a relatively simple structural design compared to motor-driven systems. The gas piston acts as a mechanical spring that automatically provides lifting force.
Solution Approach 2:
The gas piston functions as a counterweight mechanism by providing an opposing force to gravity. The compressed gas spring stores potential energy that counteracts the weight of the mobile pane, making lifting effortless for the user. This is analogous to a counterweight system where the gas piston's elastic potential energy balances the gravitational force on the pane.
3Illumination intensity
If vertical aluminum profiles are used on sides only, then the view is unlimited, but the structural support must be optimized
Solution Approach 1:
The aluminum profiles are segmented and positioned only at the vertical sides of the glass panes rather than forming a complete frame. This segmentation provides sufficient structural support at critical locations while leaving the horizontal areas open for unobstructed views. The vertical profiles at the sides bear the structural loads while minimizing visual obstruction.
Solution Approach 2:
The aluminum profiles are strategically placed only where structurally necessary (vertical sides) rather than uniformly distributed. This local placement optimizes structural support at critical stress points while maintaining view openness in other areas. The quality of structural reinforcement is concentrated where needed rather than applied uniformly throughout the entire frame.

AI summary
Glass windbreaker consisting of two parties, the stable (1) and the mobile (7), with surface made of glass (3) & (6) accordingly, has only vertical aluminum profiles (2) & (8) accordingly, and offers unlimited view, movement (up - down) of the mobile part (1) with use of nitrogen gas pistons (10) in the inner of the aluminium profile (2) and of one locking - unlocking mechanism, which consists of plastic accessories (4), (5) located at the bottom edge of the aluminium profile (2) and of the plastic pivot (6), which is on the edge of the rod (9). The glass windbreaker is on the close position when the rod (9) is compressed, but when the rod (9) is released the windbreaker is lifting upwards to the open position.
