Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driving wire is provided to operate the sunshade vertically or horizontally, then the sunshade can be opened and closed, but children may trip over the driving wire or suffocate due to their neck being wound around the driving wire
Solution Approach 1:
The patent removes the driving wire from the system entirely, replacing it with a wire rope that is wound around a spool. This extraction of the harmful element (driving wire) eliminates the safety hazards while preserving the sunshade operation functionality through the alternative mechanism of the wire rope and spool assembly.
Solution Approach 2:
The spool acts as an intermediary mechanism between the wire rope and the sunshade. Instead of using a direct driving wire, the wire rope is wound around the spool which rotates to control the sunshade movement. This intermediary component provides a safer operation mechanism that eliminates the tripping and suffocation risks associated with exposed driving wires.
2Object-generated harmful factors
If the sunshade is oscillated by an indoor air blower or air flowing in from the outside, then air circulation is achieved, but a weight member provided at the bottom of the sunshade collides with the window frame, generating noise and being unable to effectively block light
Solution Approach 1:
The patent removes the weight member from the bottom of the sunshade, eliminating the source of noise and light blocking failure. Instead of using a weight member to maintain sunshade position, the invention uses a tensioning mechanism with wires and turnbuckles that can be adjusted to maintain proper sunshade tension and position without colliding with the window frame or furniture.
Solution Approach 2:
The patent introduces adjustable turnbuckles that allow changing the tension and length parameters of the supporting wires. This parameter adjustment capability enables the sunshade to maintain optimal position and tension under various conditions, including air flow, without generating noise or failing to block light effectively.
3Ease of operation
If the weight member is provided at the bottom of the sunshade to spread the sunshade in the gravitational direction, then the sunshade can be deployed, but it collides with the window frame or furniture, causing damage and noise
Solution Approach 1:
The patent removes the weight member that causes collisions with the window frame and furniture. Instead, it uses a tensioning system with wires and turnbuckles that provides controlled deployment without the harmful effects of the weight member while maintaining sunshade stability against weather conditions.
Solution Approach 2:
The patent introduces a dynamic tensioning system with adjustable turnbuckles that allow the sunshade to adapt to various deployment conditions. The turnbuckles can be adjusted to optimize wire tension, enabling the sunshade to resist wind and rain effectively while avoiding collisions with the window frame or furniture during deployment.
4Object-affected harmful factors
If a fixed configuration is used to block direct sunlight or rainwater, then the sunshade provides protection, but it may collide with a vehicle or be damaged if there is a lot of wind, snow, or rain
Solution Approach 1:
The patent introduces a dynamic deployment system with adjustable wires and turnbuckles that allow the sunshade to be deployed at optimal angles and tensions. This dynamic configuration enables the sunshade to resist wind, snow, and rain more effectively than a fixed configuration, while still providing protection from direct sunlight and rainwater.
Solution Approach 2:
The patent uses adjustable turnbuckles to change the tension and angle parameters of the sunshade deployment. By optimizing these parameters, the sunshade achieves both effective protection from elements and enhanced resistance to wind, snow, and rain, avoiding the limitations of fixed configurations.
5Ease of operation
If the rotating shaft is installed on the wall of the building with a link device to spread the sunshade, then the sunshade can be deployed, but the foldable arm has a limit in length, so if it is stretched to an excessive length, it will be bent, making it impossible to install a wide sunshade
Solution Approach 1:
The patent removes the foldable arm mechanism with its inherent length limitations. Instead, it uses a wire rope system wound around a spool that can be extended indefinitely by unwinding the wire rope. This eliminates the length constraint that would otherwise limit the deployment of wide sunshades.
Solution Approach 2:
The patent transitions from a linear foldable arm mechanism to a radial wire rope system wound around a spool. This dimensional change allows the sunshade to be deployed in a circular pattern with no practical length limitation, as the wire rope can be unwound to extend the deployment radius as needed.
6Ease of operation
If the sunshade is supported by the arms installed symmetrically on both sides, then the sunshade can be deployed, but the arm may be damaged due to weak resistance to strong winds, heavy snow, and heavy rain
Solution Approach 1:
The patent removes the symmetric arm support structure that is vulnerable to weather conditions. Instead, it uses a central spool mechanism with wire ropes that provide superior resistance to wind, snow, and rain. The wire rope system can be tensioned to provide enhanced structural strength and weather resistance.
Solution Approach 2:
The patent employs composite construction in the wire rope system, combining multiple strands of wire to create a strong, weather-resistant support structure. This composite approach provides superior strength and resistance to environmental conditions compared to the simpler arm structure.
