Solution Overview
Problem
Manual fastening of bolts, nuts, and clips in assembly lines leads to defects and limits productivity, as it is labor-intensive and prone to errors.
Innovation Solution
A hardware automatic fastening apparatus that shares a single device for simultaneously transferring and automatically fastening multiple parts, including bolts, nuts, and clips, regardless of type, to prevent fastening interference and automate both upper and lower fastening processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual fastening is used, then labor flexibility is maintained, but productivity is limited and defects occur due to mistakes
Solution Approach 1:
The system uses sensors to automatically detect hardware types and positions, and the controller automatically adjusts parameters and controls the fastening process without manual intervention, enabling the system to serve itself and achieve high automation while maintaining productivity
Solution Approach 2:
The patent replaces manual mechanical fastening operations with an automated system that uses sensors for detection, a controller for decision-making, and automated fastening tools to perform the actual fastening, thereby eliminating human error and increasing productivity
2Adaptability or versatility
If separate devices are used for different hardware types, then each device can be optimized, but device complexity and transfer time increase
Solution Approach 1:
The patent employs a universal fastening device that can handle multiple hardware types (bolts, nuts, clips, etc.) through a single integrated system. The sensor detects the hardware type and the controller automatically adjusts parameters, allowing one device to perform multiple functions without requiring separate optimized devices for each hardware type
Solution Approach 2:
The system changes operational parameters (such as fastening torque, speed, and tool selection) based on the detected hardware type. The sensor identifies the hardware and the controller dynamically adjusts the fastening parameters to match the specific requirements of each hardware type, enabling adaptability without increasing device complexity
3Manufacturing precision
If separate devices are used for upper and lower fastening, then each fastening position can be optimized, but fastening interference occurs due to transfer
Solution Approach 1:
The patent combines the upper and lower fastening operations into a single integrated device. The sensor simultaneously detects hardware at both positions, and the controller coordinates the fastening operations to occur together or in optimized sequence, eliminating the need for separate devices and the transfer time between them while maintaining precision at each position
