Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing butt welding machines for plastic pipes cannot operate the cutter and movable claws simultaneously, limiting their efficiency and functionality.
Innovation Solution
A drive gear unit that provides synchronized motion to both the cutter and movable claws, using a separate motor to transfer power through a connector, allowing independent and simultaneous operation of the cutter and movable claws, with the option of hydraulic, pneumatic, or manual drive systems, and incorporating synchromesh gear transmission for efficient motion control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single motor is used to drive the movable claws, then the structure is simplified, but the cutter and machine cannot work synchronously
Solution Approach 1:
The patent divides the driving system into separate drive units: one motor for the movable claws and another motor or hydromotor for the cutter. This segmentation allows each component to be driven independently, enabling synchronous operation while maintaining structural simplicity through modular design.
Solution Approach 2:
The patent employs a universal driving architecture where the machine frame and support structures serve multiple functions: providing mechanical support, guiding motion paths, and serving as mounting bases for both drive systems. This multi-functionality reduces overall complexity while enabling synchronized operation.
2Ease of operation
If the cutter is mounted on itself with a motor or hydromotor, then the cutter can operate independently, but simultaneous synchronous operation with movable claws is not achieved
Solution Approach 1:
The patent merges the cutter drive system with the overall machine framework, integrating the cutter motor/hydromotor mounting and operation control into the unified machine structure. This allows the cutter to maintain operational independence while being synchronized with the movable claws through coordinated control of both drive systems.
Solution Approach 2:
The patent implements dynamic control where the cutter and movable claws can operate with adjustable speed and timing parameters. The drive systems are designed to accommodate varying operational requirements while maintaining the ability to work synchronously when needed, providing flexible productivity optimization.
