Flatwork Ironer Direct Drive Layout With Fewer Wheels and Belts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flatwork ironer driving systems are complex, costly, and prone to malfunctions due to numerous wheels and belts, making maintenance difficult and increasing production and maintenance costs.
Innovation Solution
A direct driver system using a chain, V-belt, belt, or strip as the connecting driving component, eliminating the need for secondary components like straining wheels and double wheels, and incorporating an elastic straining slider to maintain alignment and prevent waving motion, with a motor-driven gearbox and free clutch for emergency manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wheels and belts are used to drive separate rolls, then the ironer can perform multiple functions, but the device complexity and maintenance difficulty increase significantly
Solution Approach 1:
The patent combines multiple driving functions into a single integrated driving roll that directly drives all ironing strips. This eliminates the need for multiple separate wheels, belts, and chains, thereby reducing device complexity while maintaining the ability to perform multiple ironing functions through different strip configurations.
Solution Approach 2:
The single driving roll is designed to universally drive multiple ironing strips simultaneously, each strip performing different ironing functions. This multi-functional approach allows the system to maintain versatility while using a simplified single-component driving mechanism instead of multiple specialized components.
2Productivity
If multiple connecting driving components are used, then separate rolls can be driven at different angular velocities, but maintenance costs and production costs increase
Solution Approach 1:
The patent merges multiple connecting driving components into a single direct-drive mechanism where the driving roll directly contacts and drives all ironing strips. This eliminates the need for multiple belts and chains, significantly reducing production costs and maintenance requirements while still allowing different strips to operate at different angular velocities through their individual configurations.
3Ease of operation
If numerous wheels and belts are used in the driving system, then complex motion control is achieved, but the system becomes prone to malfunctions
Solution Approach 1:
The patent combines multiple separate driving mechanisms into a single integrated driving roll system. By eliminating numerous wheels, belts, and chains that are prone to malfunction, the system achieves high reliability while maintaining complex motion control capability through the direct-drive configuration of multiple ironing strips.
Solution Approach 2:
The patent extracts and eliminates the problematic intermediate components (wheels, belts, chains) from the driving system, leaving only the essential direct-drive mechanism. This removal of unnecessary components reduces the points of potential failure while preserving the required motion control functionality.
4Ease of operation
If multiple intermediate driving components are used, then motion transfer is achieved, but the number of components and system complexity increase
Solution Approach 1:
The patent merges all intermediate driving components into a single direct-drive system where the driving roll directly transfers motion to all ironing strips without intermediate wheels or belts. This eliminates the need for motion transfer through multiple components while maintaining full motion control capability.
