Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-size stopping unit with friction-based locking members (rollers or balls) is used, then the device structure is simple, but the stopping accuracy is low and reliability is poor due to wearing components
Solution Approach 1:
The patent replaces the traditional mechanical friction-based locking system (rollers or balls) with a magnetic field-based detection and control system. The first switch (sensor) detects the rod position non-contactly, and the control system activates the stopping means (mechanical stop) only when needed, eliminating continuous friction and component wear while improving reliability.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the rod and the detection system. The magnetic field allows non-contact detection of the rod's position through the rod body, enabling accurate position sensing without physical contact or friction, thus improving reliability without adding complex mechanical components.
2Adaptability or versatility
If a fixed-size device is designed for a specific working plant, then the manufacturing cost is low, but the adaptability to different working plants is poor
Solution Approach 1:
The patent makes the device adaptable by introducing adjustable positioning means for the first switch. This allows the detection position to be dynamically adjusted along the rod's path, enabling the same device to be configured for different stroke lengths and working conditions without requiring complete redesign or replacement of the device.
Solution Approach 2:
The patent creates a universal device that can serve multiple working plants and applications by combining adjustable positioning means with the core stopping function. The same basic device structure can be adapted to different requirements by adjusting the switch position, making it multi-functional and versatile across different working conditions.
3Measurement precision
If rollers or balls are used as locking members applying frictional force on the rod, then the device structure is simple, but the stopping accuracy is low due to component wearing
Solution Approach 1:
The patent replaces the mechanical friction-based detection and locking system with a magnetic field-based detection system followed by a controlled mechanical stop. The magnetic field enables precise non-contact detection of the rod's position, eliminating the need for continuous friction-based locking members and achieving high stopping accuracy without component wear.
