Roller ironing press
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller ironing presses suffer from wear and complexity in components such as rods, wheels, racks, and gas-filled cylinders, leading to high manufacturing costs and operational complications.
Innovation Solution
The use of a cable system with pulleys and elastic return means, such as helical springs, to move the presser means, reducing the number of components and minimizing wear, while maintaining a stable and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional components (rods, wheels, racks, gas-filled cylinders) are used to move the presser means, then the presser means can be moved toward the roller, but these components are subject to wear and increase device complexity
Solution Approach 1:
The patent removes the complex mechanism of rods, wheels, racks, and gas-filled cylinders from the system. Instead, it uses a cable extending between two shoulders with drive means at one end to move the presser means, extracting only the essential function of movement while eliminating unnecessary components that cause wear and complexity
Solution Approach 2:
The cable system serves multiple functions: it moves the presser means toward the roller, transmits force from the drive means, and eliminates the need for separate rods, racks, and cylinder mechanisms. This multi-functional approach reduces the overall number of components and simplifies the device structure
2Ease of manufacture
If multiple components (rods, wheels, racks, cylinders) are used for moving the presser means, then the presser means can be actuated, but manufacturing costs increase
Solution Approach 1:
The patent extracts only the essential movement function from the complex assembly of rods, wheels, racks, and cylinders. By using a simple cable with drive means, it reduces the quantity of components to be manufactured and assembled, thereby simplifying the manufacturing process and reducing costs
Solution Approach 2:
The patent merges the functions of multiple separate components (rods for movement, racks for positioning, cylinders for actuation) into a single integrated cable system with drive means. This consolidation reduces the number of parts that need to be manufactured and assembled, improving ease of manufacture
3Ease of operation
If conventional moving mechanisms (rods, racks, cylinders) are used, then the presser means can be positioned, but the construction becomes complicated and assembly is difficult
Solution Approach 1:
The patent removes the complicated construction elements (rods, racks, multiple linkage mechanisms) and retains only the essential cable and drive means. This extraction maintains the presser positioning capability while dramatically simplifying the construction and making assembly more straightforward
