Solution Overview

Problem

Slicing machines, such as centrifugal-type slicers, face challenges in accurately adjusting gate openings for precise control of slice thickness due to measurement errors caused by operator handling of gauges, especially when fine adjustments are necessary, leading to inconsistent slice thicknesses.

Innovation Solution

A gauge system comprising a frame with dial indicators, magnetic units, locator pins, and a handle, which securely attaches to the cutting head and allows for accurate measurement and adjustment of gate openings without manual holding, using spring-loaded plunger assemblies for consistent contact and reduced operator error.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual holding of gauges is used for measurement, then operator flexibility is maintained, but measurement precision deteriorates due to handling errors

Engineering Contradiction:
Improveoperator flexibilityVSAvoidgate opening measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The gauge system is self-positioning through magnetic attachment to the cutting head and automatic alignment via locator pins. The spring-loaded plunger assemblies automatically engage with the gate opening surfaces, eliminating the need for operator handling and positioning adjustments during measurement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical positioning and holding of gauges is replaced by magnetic attachment forces and spring-loaded mechanical engagement. The measurement system transitions from operator-dependent manual positioning to automatic mechanical positioning through magnetic and elastic forces.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If fine adjustments of gate openings are made, then slice thickness control is improved, but measurement errors increase due to operator handling difficulty

Engineering Contradiction:
Improveslice thickness controlVSAvoidgate opening measurement accuracy
Core Design Contradiction:
Manufacturing precisionVSMeasurement precision

Solution Approach 1:

The gauge system performs self-alignment and self-measurement during fine adjustments. The spring-loaded plungers automatically adapt to the gate opening dimensions, and the magnetic attachment ensures the gauge remains properly positioned even during delicate adjustment operations, eliminating operator-induced errors.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The gauge system is pre-positioned and pre-aligned before measurement begins through magnetic attachment and locator pin engagement. The spring-loaded plungers are pre-loaded to ensure consistent contact pressure, preparing the measurement system in advance to eliminate errors during the actual measurement of fine gate openings.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If consistent contact during measurement is achieved, then measurement precision is improved, but device complexity increases due to spring-loaded mechanisms

Engineering Contradiction:
Improvemeasurement consistencyVSAvoidgauge system structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The spring-loaded plunger assemblies utilize elastic deformation parameters to achieve consistent contact force. By changing the physical state from rigid to elastic contact, the system automatically compensates for surface irregularities and maintains constant measurement pressure, improving consistency while using simple elastic components.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The spring-loaded plungers act as intermediaries between the gauge body and the gate opening surfaces. These elastic intermediaries absorb positioning variations and surface irregularities, providing consistent contact force while isolating the measurement mechanism from direct mechanical complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
