Mast-Integrated Power Receiving Layout for Conveyance Carriages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyance devices expose the power receiving section, which is raised and lowered with the carriage, outside the mast, necessitating an improved arrangement.
Innovation Solution
The power receiving section is disposed between the first and second side sections of the mast, with a feed line along the mast supplying power, and wiring paths are designed to prevent exposure and interference with guide rollers and counterweights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power receiving section is disposed outside the mast and exposed, then it is easy to access and maintain, but it occupies external space and complicates the overall arrangement
Solution Approach 1:
The power receiving section is nested within the mast structure, specifically disposed between the first side section and second side section of the mast. This nesting approach allows the power receiving section to be housed inside the existing mast framework, improving spatial arrangement while maintaining functionality.
2Device complexity
If the power receiving section is disposed inside the mast, then the arrangement is improved and space is optimized, but wiring becomes more complex
Solution Approach 1:
The feed line is routed through wiring paths formed in the side sections of the mast, utilizing the vertical and lateral dimensions of the mast structure. This dimensional approach allows the feed line to reach the power receiving section inside the mast without creating excessive wiring complexity, as the wiring paths are integrated into the mast's side sections.
3Ease of manufacture
If the feed line is routed outside the mast, then wiring is simpler, but the power receiving section cannot be properly housed inside the mast
Solution Approach 1:
The feed line is nested within the mast structure by routing it through wiring paths formed in the side sections. This allows the feed line to be contained within the mast's framework while still reaching the power receiving section, maintaining both compact arrangement and wiring simplicity.
