Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guiding and tension spindle circuit machines require complex and expensive mechanical gearing for coupling the main and lead spindles, necessitating expertise for setting up suitable translations, which complicates thread cutting and increases manufacturing costs.
Innovation Solution
The solution involves using two drives controlled by a computer to couple the main and lead spindles without mechanical gearing, allowing for simplified setup and adjustment of translations, enabling thread cutting through a user-friendly control system that calculates and displays the desired translation, and includes features like multi-stage transmission and optional couplable gearbox for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mechanical gearbox is used to couple the main spindle and leadscrew, then the thread cutting function is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces the mechanical gearbox with an electronic control system that coordinates the main spindle and leadscrew through software algorithms. The control system calculates and enforces the appropriate transmission ratios electronically, eliminating the need for complex mechanical gearing while maintaining the thread cutting function.
Solution Approach 2:
The patent extracts and removes the mechanical gearbox from the system, separating the gear ratio function from the mechanical transmission path. The transmission ratio calculation and enforcement are transferred to the electronic control system, simplifying the mechanical structure while preserving the functional relationship between spindle and leadscrew.
2Ease of operation
If a mechanical gearbox is used to couple the main spindle and leadscrew, then the thread cutting function is achieved, but the setup complexity and expertise requirement increase
Solution Approach 1:
The patent replaces the mechanical gearbox setup process with an electronic control system that automatically calculates and configures the appropriate transmission ratios. The control system uses algorithms to determine the correct gear ratios based on thread pitch requirements, eliminating the need for manual mechanical setup and reducing the expertise required for operation.
Solution Approach 2:
The control system performs self-configuration by automatically calculating the appropriate transmission ratios based on the desired thread parameters. The system adapts to different thread cutting requirements without requiring manual intervention or expert knowledge for setup, making the machine easier to operate for users with varying skill levels.
3Ease of manufacture
If angle detection devices and electronic control are used to couple drives, then the device complexity increases, but the manufacturing cost decreases
Solution Approach 1:
The patent replaces complex mechanical gearing with a relatively simple electronic control system that uses angle detection devices to coordinate the drives. The electronic system requires fewer physical components than a mechanical gearbox while achieving the same functional outcome, thereby reducing manufacturing cost despite the introduction of electronic elements.
