Replaceable Non-Welded Slice Blade Assembly for Low-Downtime Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slicer blade assemblies for automatic high-speed equipment require complete replacement when blades need changing, leading to increased costs, complex clinch mechanisms causing sanitation issues, and potential brittleness due to welding.
Innovation Solution
A removably attached slicer blade assembly with reusable support members, eliminating welding and allowing for adjustable blades to be used in multiple configurations, reducing replacement costs and downtime by enabling blade replacement without replacing the support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the blade assembly is welded together as in prior art, then the structure is strong and stable, but the blade becomes brittle and the entire assembly must be replaced when the blade wears out
Solution Approach 1:
The blade assembly is divided into separate components: the blade element and the support member are distinct parts that can be independently replaced. The blade element can be detached and replaced without affecting the support member, allowing only the worn blade to be discarded while reusing the durable support structure.
Solution Approach 2:
The design enables selective discarding of only the blade element when it wears out, while the support member is recovered and reused. This contrasts with welded assemblies where the entire structure must be replaced, significantly reducing material waste and operational costs.
2Reliability
If a complex clinch mechanism is used to attach the blade, then the blade is securely held, but sanitation becomes difficult and requires periodic cleaning
Solution Approach 1:
The complex clinch mechanism is removed from the design. Instead, a simple friction-fit attachment method is used where the blade element is held securely by friction between the support member and blade, eliminating the need for complex retaining structures that are difficult to clean.
Solution Approach 2:
The blade element is designed as a simple, inexpensive component that can be easily replaced. The simplicity of the attachment mechanism allows for easy sanitation while maintaining secure blade retention during operation.
3Force
If multiple welds are applied to the blade, then the blade is firmly attached to the support, but the blade becomes brittle and potentially weakened
Solution Approach 1:
Welding is replaced with a friction-based mechanical attachment system. The blade element is secured through friction fit between the support member and blade, eliminating thermal processes that cause brittleness while maintaining sufficient attachment force for high-speed slicing operations.
4Ease of repair
If the entire blade assembly must be replaced when the blade wears out, then blade replacement is simple, but downtime increases and costs increase
Solution Approach 1:
The blade assembly is segmented into replaceable blade elements and permanent support members. This allows operators to quickly swap individual blade elements without replacing the entire assembly, significantly reducing downtime and maintenance costs while maintaining ease of replacement.

AI summary
A slice blade assembly for various produce items is provided. A circular array of V-shaped blades is carried in an outer support ring. Each blade is held in place by a new non-welded block and nut which interlock with bent tabs formed at the tips of each blade. Each blade is adjustable since each blade is bendable at its apex. Each worn or damaged blade may be removed and replaced without replacing the block and nut that support the blade.
