Solution Overview
Problem
Existing cutting apparatuses face difficulties in understanding the relationship between lamps and blades, making it challenging to achieve precise cutting of sheet-shaped materials.
Innovation Solution
A cutting apparatus unit with a detection means comprising a holder, a first and second shaft, and blade members, where the detection means includes a power source, connection terminal, light emitting device, and wiring to electrically connect these components, allowing for precise detection of blade contact without requiring complex modifications to the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lamps are attached to the apparatus body to detect blade contact, then blade contact detection is enabled, but it becomes difficult to understand the corresponding relationship between lamps and blades when the number and position of blades are changed
Solution Approach 1:
The patent combines the lamp and its corresponding blade into a single integrated unit. Each lamp is directly attached to its corresponding blade, ensuring that when blades are repositioned or replaced, the lamps move with them, maintaining clear correspondence without requiring separate attachment to the apparatus body.
Solution Approach 2:
The patent creates a visual copy or indicator system where the state of each blade is directly represented by its attached lamp. The lamp serves as a visual copy of the blade's operational state, making it immediately clear which lamp corresponds to which blade through direct physical attachment.
2Adaptability or versatility
If the number and position of blades are changed to obtain cut pieces with desired width, then cutting versatility is improved, but it becomes difficult to maintain clear correspondence between lamps and blades
Solution Approach 1:
By merging the lamp and blade into a single integrated unit, the patent eliminates the complexity of managing separate lamp-blade correspondences. When blades are repositioned for different cutting widths, their attached lamps automatically relocate with them, maintaining clear correspondence without additional management effort.
Solution Approach 2:
The patent creates a dynamic system where lamps are not fixed to the apparatus body but are instead attached to movable blades. This allows the lamp-blade system to dynamically adapt to changing blade configurations while maintaining clear correspondence through their permanent association.
