Multi-Drive Wire Saw Layout for Constant Contact Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire saws are either too large and unwieldy due to large drive wheels and motors, leading to high production costs and uneven load distribution, while prior solutions with multiple roller batteries result in variable contact length and increased load on the saw rope or drive wheels.
Innovation Solution
A wire saw design featuring at least three independent drive wheels that maintain constant contact length regardless of rope storage occupancy, utilizing a pulley-like rope storage system and smaller drive motors, allowing for a compact and powerful saw with efficient space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If large drive wheels are used to provide sufficient contact length, then the contact length between saw wire and drive wheels is improved, but the wire saw becomes very large and unwieldy
Solution Approach 1:
The patent divides the single large drive wheel into multiple smaller drive wheels (at least three). Each drive wheel has a groove for the saw wire, and they are arranged to provide sufficient total contact length without requiring large individual wheel diameters. This segmentation allows the wire saw to be compact while maintaining adequate contact length for force transmission.
2Power
If large drive motors are used to drive large drive wheels, then the power transmission capability is improved, but the installation volume and cost increase
Solution Approach 1:
The patent segments the power transmission system into multiple smaller drive wheels that can be driven by smaller, more readily available motors. This eliminates the need for large, expensive, custom-manufactured motors while maintaining sufficient power transmission capability through the combined contact of multiple drive wheels.
Solution Approach 2:
The drive wheels serve multiple functions: they transmit drive force to the saw wire, store the saw wire when not in use (wire storage unit), and provide guidance. This multi-functionality reduces the need for separate components and allows smaller motors to suffice.
3Quantity of substance
If the number of occupied storage levels increases, then the wire storage capacity is improved, but the contact length changes leading to increased load on saw wire or drive wheels
Solution Approach 1:
The patent uses at least three separate drive wheels instead of a single large wheel or two roller assemblies. This segmentation ensures that the contact length and load distribution remain consistent regardless of how much wire is stored, because each drive wheel maintains its own contact zone with the wire.
Solution Approach 2:
The wire storage unit is designed to accommodate varying wire lengths while the drive wheels maintain constant contact. The system dynamically adapts to different storage levels without compromising the mechanical load distribution, as the multiple drive wheels ensure consistent force transmission across the saw wire.
