Solution Overview
Problem
Current potato chip manufacturing methods face challenges with large potato slices, leading to inefficient packaging, increased production costs, and consumer complaints due to oversized chips, which are difficult to package and result in waste and reduced productivity.
Innovation Solution
An apparatus with an annular-shaped cutting head and central impeller that includes orientation elements to deflect elongate potatoes, ensuring they are cut into slices with a desired width, reducing oversized chips by orienting them radially before cutting, thereby improving packaging efficiency and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large potatoes are used to manufacture potato chips, then productivity and efficiency increase, but packaging problems occur due to oversized chips that are difficult to package
Solution Approach 1:
The patent segments the potato cutting process by introducing orientation elements that divide the impeller into multiple zones, ensuring potatoes are properly oriented before cutting. This segmentation allows large potatoes to be cut into uniformly sized slices that meet packaging requirements while maintaining high productivity
Solution Approach 2:
The orientation elements perform preliminary action by orienting potatoes in the radial direction before they reach the cutting head. This preliminary orientation ensures that even large potatoes will be cut into slices of appropriate size for packaging, preventing packaging problems before they occur
2Ease of operation
If potatoes are graded to be small prior to processing, then packaging problems are minimized, but productivity and efficiency reduce
Solution Approach 1:
The patent changes the parameter of slice width control by introducing orientation elements that ensure proper radial orientation of potatoes during cutting. This allows the use of large potatoes with high productivity while still producing slices of appropriate size for packaging, eliminating the need for restrictive grading
3Manufacturing precision
If a grader halver is used to cut potatoes in half prior to slicing, then slice dimensions are reduced, but production line cost increases and production speeds reduce
Solution Approach 1:
The patent merges the orientation function and cutting function into a single integrated cutting head assembly. The orientation elements are incorporated directly into the impeller structure, eliminating the need for separate grader halvers and reducing device complexity while maintaining precise slice dimension control
Solution Approach 2:
The orientation elements perform preliminary orientation of potatoes in the radial direction before cutting occurs. This preliminary action ensures proper slice dimensions without requiring additional halving equipment, maintaining production speed while achieving precise dimension control
4Reliability
If packaging speed is lowered to accommodate large potato chips, then packaging reliability improves, but productivity decreases
Solution Approach 1:
The patent changes the parameter of slice width distribution by implementing orientation elements that ensure all potato slices fall within the acceptable width range for standard packaging machines. This allows packaging to proceed at high speed without compromising reliability, as no oversized chips will jam the packaging mechanism
