Composite Blade System Segmentation for Inventory Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cutting facilities face challenges due to the individuality of machines and blades, leading to increased costs in storage, inventory, and manufacturing, as well as complications in blade manufacturing and sharpening processes.
Innovation Solution
The composite blade system consists of a three-piece system: a blade hub, a plurality of blade segments, and a locking plate. This system allows for interchangeable blade segments, enabling adaptation to various machine sizes and cutting processes, thereby simplifying manufacturing and sharpening processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual custom blades are manufactured for each machine, then each machine can be optimized for its specific cutting needs, but manufacturing costs and inventory complexity increase significantly
Solution Approach 1:
The blade is divided into multiple interchangeable segments that can be combined in different configurations. Each segment can be optimized for specific cutting tasks, and segments are standardized with uniform mounting interfaces. This allows custom blade configurations for different machines while using a shared library of standardized segments, reducing overall inventory complexity.
Solution Approach 2:
A universal hub design with standardized interfaces allows the same blade segments to be used across multiple different cutting machines. The hub provides a common mounting mechanism that accommodates various segment combinations, enabling one set of segments to serve multiple machine types and cutting applications.
2Adaptability or versatility
If multiple blade sizes and types are maintained in inventory, then all machine requirements can be met, but storage costs and inventory management complexity increase
Solution Approach 1:
Instead of storing complete custom blades for each machine application, only individual blade segments need to be inventoried. These standardized segments can be quickly recombined into different blade configurations as needed, dramatically reducing the total quantity of blade material that must be stored while maintaining the ability to meet all machine requirements.
Solution Approach 2:
The system enables dynamic change of blade parameters (such as diameter, cutting edge configuration, and segment composition) by recombining standardized segments. This allows the same physical segments to be configured for different machine requirements, eliminating the need to maintain separate inventory for each parameter variation.
3Reliability
If complete blades are sharpened when dull, then cutting performance is restored, but the entire blade must be processed even if only one edge is worn
Solution Approach 1:
The blade is composed of replaceable segments, allowing only the worn or dull segment to be removed and replaced with a sharp one. This eliminates the need to sharpen the entire blade when only one segment becomes dull, significantly reducing sharpening time and resource consumption while maintaining cutting performance.
Solution Approach 2:
Instead of sharpening worn segments, the system allows direct replacement of dull segments with pre-sharpened ones. The removed segments can be sent for professional sharpening or replacement, while the main blade assembly remains in service, minimizing downtime and resource investment.
4Ease of manufacture
If a single large blade is manufactured, then manufacturing processes are simplified, but the blade cannot be adapted to different machine sizes
Solution Approach 1:
The blade is divided into multiple smaller segments that can be manufactured using standardized processes and then assembled into different-sized complete blades. Each segment can be produced efficiently using uniform manufacturing methods, and the segments can be combined in various configurations to create blades of different diameters and specifications for different machine sizes.
Solution Approach 2:
Multiple smaller blade segments are nested or arranged around a central hub to form the complete blade assembly. This modular construction allows the same set of segments to be configured for different blade sizes by changing the arrangement or number of segments, providing adaptability to different machine sizes while maintaining simple standardized manufacturing for each segment.

AI summary
This disclosure relates generally to cutting processes, composite blades, blade systems, and manufacturing and use thereof. In various aspects, a composite blade system includes a plurality of blade segments, where each blade segment includes a body having top edge, a bottom edge, and opposing side edges extending therebetween. The blade segments also include a projection on a first side edge of the body, a slot on a second side edge of the body opposite the first side edge, and a void disposed near the bottom edge of the body. The composite blade system may additionally include a hub connectable to each of the plurality of blade segments via the void and a locking plate connectable to the hub.
