Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece support devices struggle to flexibly accommodate both continuous and non-continuous rotation applications in arc-welding processes, as they often require different configurations for power supply and protection against foreign matter, leading to inefficiencies and unnecessary wear.
Innovation Solution
A workpiece support device with a rotatable conductive work table, a removable current-collecting brush, and a modular cover system composed of disassemblable segments, allowing for easy adaptation between continuous and non-continuous rotation applications by adjusting the cover and power supply configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed cover and power supply configuration is used, then the device structure is simple, but it cannot flexibly accommodate both continuous and non-continuous rotation applications
Solution Approach 1:
The cover is divided into multiple segments that can be independently assembled or disassembled. This segmentation allows the cover to be configured differently for continuous rotation applications (where all segments are assembled to protect against foreign matter) and non-continuous rotation applications (where segments can be removed to prevent wear), thereby resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The power supply configuration is made dynamic through the removable current-collecting brush and disassemblable cover segments. This allows the system to adapt its configuration based on operational requirements, enabling flexibility between continuous and non-continuous rotation modes without requiring a completely different device structure.
2Object-affected harmful factors
If the cover is always assembled to protect against foreign matter, then protection is effective, but unnecessary wear occurs during non-continuous rotation applications
Solution Approach 1:
The segmented cover design allows selective assembly and disassembly of cover segments. During continuous rotation applications, all segments are assembled to provide complete protection against foreign matter. During non-continuous rotation applications, segments can be disassembled to prevent unnecessary wear on the current-collecting brush and work table, thus resolving the contradiction between protection effectiveness and component reliability.
Solution Approach 2:
The system changes the configuration parameter of the cover (assembled vs. disassembled state) based on the rotation application type. This parameter change allows the device to optimize both protection against foreign matter and prevention of component wear by adapting the cover configuration to the specific operational requirements.
3Use of energy by moving object
If the current-collecting brush is always in contact to supply power, then power supply is continuous, but unnecessary wear occurs during non-continuous rotation applications
Solution Approach 1:
The current-collecting brush configuration is made dynamic and removable, allowing the system to establish or disconnect power supply based on operational needs. During continuous rotation applications, the brush remains in contact for continuous power supply. During non-continuous rotation applications, the brush can be removed to prevent unnecessary wear, resolving the contradiction between power supply continuity and brush reliability.
