Slicer Whetting Device With Form-Fit Stop Plate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing whetting devices for slicers are limited to a specific type and require complex adjustments to be used on different slicers, as they do not align properly with the circular blade due to varying tolerances in blade guard rings and carriages.
Innovation Solution
A whetting device with a mount that includes an insertion apparatus with lugs and a U-shaped plate receptacle, allowing form-fitting attachment to a slicer's stop plate, ensuring precise alignment without additional adjustments, enabling use across multiple slicers of the same type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a whetting device is allocated to a specific slicer with adjustment via slots, then the whetstone and hone are aligned with the circular blade at very low tolerances, but the device cannot be used on different slicers without re-adjustment
Solution Approach 1:
The patent introduces a stop plate as an intermediary component between the slicer and the whetting device. The stop plate features a recess that receives a protrusion on the whetting device, creating a precise positioning interface. This mediator transfers the alignment function from the variable-tolerance blade guard ring to the stop plate, enabling the whetting device to be accurately positioned on different slicers without re-adjustment.
Solution Approach 2:
The patent segments the positioning function into separate components: the stop plate (attached to the slicer) and the whetting device with its protrusion. This segmentation allows the whetting device to be decoupled from the specific slicer configuration, enabling it to be used on multiple slicers while maintaining alignment precision through the standardized protrusion-recess interface.
2Ease of operation
If the whetting device is fastened to the blade guard ring, then it can be positioned on the slicer, but the blade guard ring is arranged only within rough geometric tolerance in relation to the circular blade
Solution Approach 1:
The stop plate serves as an intermediary that decouples the mounting function from the blade guard ring. By attaching the whetting device to the stop plate rather than directly to the blade guard ring, the system separates the coarse positioning (blade guard ring) from the fine positioning (stop plate recess), thereby achieving both ease of mounting and high geometric precision.
3Reliability
If components like blade guard ring and carriage do not satisfy tolerance specifications, then the whetting device must be adjusted during production, but this increases production complexity and time
Solution Approach 1:
The stop plate is pre-configured with a recess positioned at the correct location and orientation relative to the circular blade during slicer assembly. This preliminary action eliminates the need for field adjustment of the whetting device, as the pre-positioned recess automatically provides the correct alignment when the protrusion is inserted, thereby reducing production complexity while maintaining operational reliability.

AI summary
A whetting device is for a slicer. The whetting device has: a whetstone that sharpens a circular blade of the slicer; a hone that deburrs the circular blade; a handle that moves the whetstone or the hone toward the circular blade; and a mount for fastening to a stop plate of the slicer. The mount has an insertion apparatus for being form-fittingly inserted into the stop plate. The mount having a U-shaped plate receptacle, which has a gap for introducing the stop plate into the gap in when the whetting device is pushed onto the stop plate. The insertion apparatus has a lug for engaging in an recess in the stop plate, or the stop plate has the lug for engaging in the recess in the insertion apparatus.
