V-Shaped Food Cutting Blade Mounts That Prevent Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blade assemblies for cutting food, particularly those with V-shaped blades, face issues with torsional loading and rotation due to repeated impacts, leading to misalignment and inefficiency in high-speed cutting systems, which is costly and affects the quality of cuts.
Innovation Solution
A blade assembly design featuring a blade support frame with strategically positioned blade mounts that inhibit V-shaped blade rotation by overlying both edges of the blade ends, and using removable fasteners or pins to secure the blades, ensuring they remain aligned and functional during high-speed cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If V-shaped blades are used for high-speed cutting, then cutting speed and productivity are improved, but the blades are subjected to repeated impacts causing torsional loading and rotation leading to misalignment
Solution Approach 1:
The blade assembly is segmented into multiple V-shaped blades arranged in a circular pattern, with each blade independently mounted on blade mounts. This segmentation allows each blade to be individually secured while maintaining overall system functionality at high cutting speeds
Solution Approach 2:
The blade mounts are pre-positioned and secured to the support frame before the blades are installed. The mounting structure is prepared in advance with slots and fastening mechanisms ready to receive the blades, ensuring proper alignment and secure attachment before operational impacts occur
2Stability of the object's composition
If blade mounts overlie both edges of the blade ends to inhibit rotation, then blade alignment stability is improved, but the device complexity increases
Solution Approach 1:
The blade mounts serve multiple functions: they secure the blades to the support frame, provide alignment references through overlying edges, and facilitate easy removal and reinstallation. This multi-functionality reduces the need for separate alignment mechanisms, thereby limiting the increase in device complexity
Solution Approach 2:
The blade mounts extend radially outward from the support frame in a direction perpendicular to the blade cutting edges. This dimensional arrangement allows the mounts to overlie both edges of each blade end, creating a physical constraint against rotation without adding complex mechanical restraint mechanisms
3Ease of repair
If removable fasteners are used to secure blades, then ease of repair and blade replacement are improved, but the reliability of blade attachment may be compromised
Solution Approach 1:
The blade mounts are pre-equipped with slots and fastening mechanisms that guide the blades into proper position during installation. This preliminary preparation ensures that even with removable fasteners, the blades achieve correct alignment and secure attachment, maintaining reliability while allowing easy replacement
Solution Approach 2:
The mounting system replaces permanent mechanical welding or rigid fastening with removable fasteners that can be quickly installed and removed. The design compensates for the reduced permanence through precise geometric fitting and overlying mount structures that physically constrain blade movement, maintaining attachment reliability despite ease of removal

AI summary
A blade assembly includes a blade support frame, and a plurality of V-shaped blades removably fastened to the blade support frame. The blade support frame has a food flow path extending downstream, and a plurality of blade mounts distributed around the food flow path. Each V-shaped blade has a first end portion connected to one of the blade mounts, a second end portion connected to another of the blade mounts, and an intermediate portion extending from the first end portion to the second end portion into the food flow path. At the first and second end portions of each V-shaped blade, a respective one of the blade mounts overlies both the upstream edge and the downstream edge of the V-shaped blade to inhibit the V-shaped blade from rotating when impacted by food.
