Solution Overview
Problem
Bolt driving devices often face setting failures and damage to fasteners or substrates when encountering harder components in heterogeneous subsoils, as they struggle to adapt driving energy in real-time to unforeseen conditions during the driving process.
Innovation Solution
A bolt driver equipped with a control unit and sensor device that detects parameters like force and acceleration during the driving process, allowing for adaptive control of driving energy transmission, including the option to reduce or divert energy, thereby minimizing the risk of damage by adjusting energy delivery in response to unusual braking or deflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a bolt driving device delivers full driving energy to push a fastener into the substrate, then the fastening operation can be completed, but the fastener may be damaged or the substrate may be damaged when encountering harder components in heterogeneous substrates
Solution Approach 1:
The patent implements dynamic control of driving energy by continuously monitoring the driving process through sensor devices that detect parameters such as driving force, acceleration, or velocity. The control unit adjusts the driving energy in real-time based on detected anomalies, transitioning from a static full-energy delivery system to a dynamic adaptive system that responds to actual substrate conditions during fastening operations
Solution Approach 2:
The patent employs feedback control mechanisms where sensor devices monitor the driving process and transmit signals to the control unit. When anomalies such as unusual deceleration or excessive force are detected, the control unit receives feedback and automatically adjusts the driving energy accordingly, creating a closed-loop control system that prevents damage while ensuring fastening completion
2Adaptability or versatility
If a bolt driving device uses fixed driving energy delivery, then the device structure remains simple, but the device cannot adapt to unforeseen conditions during the driving process
Solution Approach 1:
The patent implements self-service control where the bolt driving device autonomously monitors its own driving process and automatically adjusts its driving energy without external intervention. The control unit uses signals from sensor devices to self-regulate the driving energy delivery, enabling the system to adapt to unforeseen conditions while maintaining operational simplicity for the user
Solution Approach 2:
The patent replaces traditional mechanical control mechanisms with electronic or electromechanical control systems. Sensor devices detect driving parameters and transmit electrical signals to the control unit, which then electronically adjusts the driving energy delivery, substituting complex mechanical adjustment mechanisms with more compact and controllable electronic systems
