Manual Ceramic Cutter Cutting and Separating Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual ceramic cutters with integrated cutting and separating tools require substantial force and complex manual manipulation to actuate the separator, often necessitating two hands and lacking adjustability for varying ceramic part thicknesses.
Innovation Solution
A cutting and separating device with a collapsible handle and toothed actuator mechanism that allows one-handed operation by rotating the handle, enabling different relative positions between the handle and separator based on ceramic part thickness through a toothed section with multiple teeth for engaging and disengaging the separator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the separator and cutting tool are mounted directly on the handle as in prior art, then the separator can be actuated by the handle, but substantial force is required and two hands are needed for manipulation
Solution Approach 1:
A connecting rod is introduced as an intermediary mechanism between the handle and the separator. The connecting rod includes a first end connected to the handle and a second end connected to the separator, transmitting the actuation force from the handle to the separator while reducing the direct force requirement on the user.
Solution Approach 2:
The separator is designed with collapsible characteristics, allowing it to transition between extended and retracted positions. This dynamic structure enables the separator to be actuated with less force by allowing controlled movement and positioning during the separation process.
2Reliability
If levers are added to arrange the separator in operative or inoperative positions, then the separator can be positioned correctly, but the user must manipulate multiple components requiring two hands
Solution Approach 1:
The positioning function previously requiring separate levers is merged into the handle itself. The handle is designed with a collapsible structure that integrates both the actuation and positioning functions, allowing the user to control the separator's operative and inoperative positions through a single handheld component.
Solution Approach 2:
The handle serves multiple functions: it acts as both the actuation mechanism for moving the separator and the positioning mechanism for setting the separator in operative or inoperative positions. This multi-functional design eliminates the need for separate levers and reduces the complexity of the overall system.
3Ease of manufacture
If the separator is fixed in a specific relative position with respect to the handle, then the structure is simple, but it cannot accommodate varying ceramic part thicknesses
Solution Approach 1:
The separator is designed as a collapsible component that can change its position relative to the handle. It includes a first position for separating thick ceramic parts and a second position for separating thin ceramic parts, allowing the same device to adapt to varying material thicknesses without requiring multiple specialized tools.
Solution Approach 2:
The relative position between the separator and handle is made variable rather than fixed. The separator can be adjusted to different positions along the handle's longitudinal axis, changing the geometric parameters of the system to accommodate different ceramic part thicknesses while maintaining structural simplicity.

AI summary
The invention relates to a cutting and separating device applicable to manual ceramic cutters, comprising: a carriage (1); a collapsible handle (3) with a cutting tool (4); a toothed part (5) comprising a separator (6) for separating ceramic parts; springs (10, 13) for holding the toothed part (5) in an inoperative position as well as a toothed actuator (12) in an engaged position with the toothed part (5); and a manual trigger element (14, 15) for disengaging the toothed actuator (12). The rotation of the handle (3) past a pre-determined angle causes the engagement of the toothed actuator (12) in the toothed part (5); the descending rotation causes the toothed actuator (12) to rotate the toothed part (5) until an operative position of the separator (6) is reached; and the actuation of the trigger element (14, 15) causes the release of the toothed part (5) and the return thereof to the inoperative position.
