Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment mechanism is used for opening and closing umbrella surface, then device complexity is reduced, but ease of operation deteriorates due to requiring continuous manual intervention
Solution Approach 1:
The sunshade system automatically opens or closes the umbrella surface based on light intensity sensor detection, eliminating the need for continuous manual adjustment. The controller activates the driving mechanism when sunlight exceeds preset thresholds, enabling the system to serve itself without human intervention.
Solution Approach 2:
The patent replaces the traditional purely mechanical manual adjustment system with an intelligent control system that integrates light intensity sensors, controllers, and electric driving mechanisms. This substitution automates the operation while maintaining mechanical execution through the driving mechanism.
2Adaptability or versatility
If fixed angle structure is used for sunshade, then device complexity is reduced, but adaptability deteriorates due to inability to adjust to different sunlight conditions
Solution Approach 1:
The sunshade structure transitions from a fixed angle design to a dynamic adjustable system. The supporting rod can rotate horizontally and the top rod can rotate vertically, allowing the sunshade angle to adapt dynamically to different sunlight directions and intensities through electrically driven rotation mechanisms.
Solution Approach 2:
The patent enables change in the geometric parameters of the sunshade structure by allowing rotation of the supporting rod and top rod at different angles. This parameter adjustment capability enables the system to adapt to varying environmental conditions while maintaining structural integrity.
3Extent of automation
If automated driving mechanisms are added for angle adjustment, then ease of operation improves, but device complexity increases due to multiple motors and sensors
Solution Approach 1:
The controller serves multiple functions by receiving signals from both light intensity sensors and wind speed sensors, then coordinating both the driving mechanism for opening/closing and the rotation mechanisms for angle adjustment. This multi-functionality reduces the need for separate control systems for each automation function.
Solution Approach 2:
The patent combines multiple sensing functions (light intensity detection and wind speed detection) and multiple actuation functions (opening/closing and angle adjustment) into an integrated system controlled by a single controller, reducing overall system complexity despite the added automation capabilities.
4Manufacturing precision
If mechanical rotation mechanism is used for supporting rod, then manufacturing precision is improved, but reliability deteriorates due to mechanical wear and friction
Solution Approach 1:
The patent replaces traditional mechanical rotation mechanisms with electrically driven rotation mechanisms. The first rotation mechanism and second rotation mechanism use electric motors to rotate the supporting rod and top rod respectively, eliminating mechanical wear and friction while maintaining precise angular control through electrical actuation.
