Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corrugation processes are limited by inflexible roller setups, high costs, and difficulties in producing larger amplitudes or materials with low plasticity, such as rubber or certain plastics, which restrict the versatility and efficiency of corrugated material production.
Innovation Solution
A method and apparatus that use upper and lower drive rollers to drive substrates at different velocities, allowing a middle substrate to form flutes between them, enabling adjustable corrugation patterns and adaptable substrate materials, including those with low plasticity, while reducing the need for multiple roller sets and improving manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional corrugating rollers with fixed dimensions are used, then corrugation frequency and amplitude are determined, but real-time adjustment capability is lost and roller replacement downtime increases
Solution Approach 1:
The patent applies dynamics by making the corrugation frequency and amplitude adjustable in real-time through variable speed drives on the corrugating rollers, eliminating the need for physical roller changes. The system transitions from static fixed-dimension rollers to dynamic adjustable rollers, allowing continuous modification of corrugation parameters during operation.
Solution Approach 2:
The patent implements parameter changes by enabling continuous adjustment of roller rotation speeds to modify corrugation frequency and amplitude without changing physical roller dimensions. This allows the system to adapt corrugation parameters dynamically, replacing the need for multiple fixed-dimension roller sets.
2Adaptability or versatility
If multiple sets of corrugating rollers with different dimensions are purchased to achieve different corrugation patterns, then production versatility is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies universality by designing a single set of corrugating rollers that can perform multiple functions through variable speed control. Instead of requiring separate roller sets for different corrugation patterns, one universal roller system can generate various frequencies and amplitudes by adjusting rotation speeds, reducing the number of components needed.
Solution Approach 2:
The system transitions from multiple static roller sets to one dynamic roller set with adjustable speeds, enabling real-time reconfiguration of corrugation patterns without physical component changes.
3Shape
If conventional corrugating rollers are used for larger amplitude corrugations (1 inch to several feet), then the corrugation size increases, but roller size becomes cost-prohibitive
Solution Approach 1:
The patent applies parameter changes by using variable speed drives on standard-sized rollers to achieve larger effective corrugation amplitudes. Instead of building physically larger rollers, the system modifies operational parameters (rotation speeds) to create the desired corrugation scale, avoiding the cost of oversized roller manufacturing.
Solution Approach 2:
The system creates the effect of large-amplitude corrugations using smaller, more economical rollers by manipulating speed ratios, essentially copying the functional outcome of large rollers without the associated manufacturing costs.
4Adaptability or versatility
If conventional corrugating rollers are used on materials with low plasticity and high memory (rubber, certain plastics), then the material may not hold its shape after molding, but using these materials limits substrate versatility
Solution Approach 1:
The patent applies periodic action through reciprocating or oscillating motion of the corrugating rollers, repeatedly forming and setting the corrugation pattern in the material. This periodic reinforcement helps materials with low plasticity maintain their shape by continuously impressing the waveform pattern rather than relying on a single pass.
Solution Approach 2:
The system modifies operational parameters such as roller speed, pressure, and reciprocation frequency to optimize shape retention for different material types, allowing versatile substrate processing while maintaining reliability for challenging materials with low plasticity.
