Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing riveting devices are used to automatically rivet workpieces, then riveting efficiency is improved, but riveting accuracy and quality deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where a detector measures the pressure acting on the fastener during assembly and generates a pressure signal. The drive unit responds to this signal to control the pressure magnitude within a preset range, creating a closed-loop control system that ensures consistent assembly quality while maintaining automated efficiency.
Solution Approach 2:
The patent dynamically adjusts the pressure parameter during the assembly process by controlling the actuator's movement based on real-time pressure feedback. This parameter control ensures that the force applied to the fastener remains within optimal ranges, preventing both inadequate assembly and damage to components.
2Object-affected harmful factors
If force acting on fastener is too small, then assembly process is gentle, but assembly accuracy deteriorates due to inadequate assembly
Solution Approach 1:
The detector continuously monitors the pressure acting on the fastener and provides feedback to the drive unit. This feedback mechanism ensures that the pressure remains within a preset optimal range, preventing both excessive force that could damage the fastener and insufficient force that would result in inadequate assembly.
Solution Approach 2:
The system dynamically adjusts the pressure applied to the fastener during the assembly process rather than using a fixed force. The actuator's movement is controlled in real-time based on pressure feedback, allowing the system to adapt pressure levels to maintain optimal assembly conditions throughout the process.
3Productivity
If force acting on fastener is too large, then assembly speed is improved, but reliability deteriorates due to fastener detachment risk
Solution Approach 1:
The pressure detector provides real-time feedback on the force applied to the fastener, enabling the drive unit to control the pressure within a preset range. This prevents excessive force that would cause fastener detachment while maintaining sufficient force for reliable assembly, thus improving both speed and reliability.
Solution Approach 2:
The system pre-establishes a preset pressure range based on optimal assembly parameters before the assembly process begins. The feedback control system ensures that the actual pressure remains within this predetermined safe and effective range, preventing reliability issues before they occur.

AI summary
An assembly mechanism includes an actuator, a first drive unit, and a first detector. The first drive unit is connected to the actuator, and the first drive unit is used for driving the actuator to move in a first direction, so that the actuator assembles a fastener. The first detector is used for obtaining a magnitude of a pressure acting on the fastener by the actuator and generating a pressure signal, and the first drive unit responds to the pressure signal to control the magnitude of the pressure acting on the fastener by the actuator within a preset range.
