Solution Overview
Problem
Existing mandoline slicers face limitations in adjusting slice thickness due to various techniques that are not efficient or user-friendly, requiring improvements in the mechanism for adjusting the offset between the cutting blade and the runway.
Innovation Solution
A mandoline-type food slicer with a movable adjustment mechanism featuring guide tracks and a gear mechanism that allows for precise adjustment of the cutting thickness by moving the runway relative to the cutting blade, enabling easy selection of slice thickness through a knob-operated system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a gear mechanism with guide tracks is used to adjust the offset between the runway and cutting blade, then the precision and ease of adjustment is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex multi-component mechanical adjustment systems with a streamlined gear mechanism that directly translates rotational motion into precise linear displacement of the runway. The guide tracks work in conjunction with the gear mechanism to eliminate the need for multiple separate adjustment components, reducing overall mechanical complexity while maintaining high precision control over slice thickness.
Solution Approach 2:
The gear mechanism converts rotational parameter (knob rotation angle) into linear parameter (runway offset distance) with a precise mathematical relationship. This parameter transformation provides exact control over slice thickness through simple rotational input, achieving high measurement precision without requiring complex mechanical linkages or multiple adjustment stages.
2Adaptability or versatility
If the runway is made movable relative to the landing to enable thickness adjustment, then the adaptability is improved, but the stability of the structure deteriorates
Solution Approach 1:
The runway is designed with controlled mobility, allowing it to move vertically relative to the landing when adjustment is required, while maintaining structural integrity during operation. The guide tracks provide defined motion paths that ensure the runway moves only in the intended direction and degree, preventing unwanted structural instability while enabling adaptability for different slice thicknesses.
Solution Approach 2:
The guide tracks serve as intermediary elements between the movable runway and the fixed landing structure. These tracks mediate the interaction by providing constrained guidance that allows necessary movement for thickness adjustment while maintaining overall structural stability. The gear mechanism acts as another intermediary, controlling the runway's movement to balance adaptability with structural integrity.
