Sheet Cutting Device Remnant Distribution Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet cutting devices generate unevenly distributed remnants during cutting, which can cause trouble in subsequent processes and require frequent collection, as the remnants accumulate near the vertically downward side of the cutting area, potentially escaping the waste box and interfering with new sheets.
Innovation Solution
A sheet cutting device with a support section made of film, featuring a comb-like shape with teeth that temporarily support and redirect remnants, ensuring they fall evenly into the waste box, reducing uneven distribution and preventing interference with new sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sheet is cut gradually from one end portion to the other end portion, then the cutting process can be completed thoroughly, but the remnants are stored unevenly in the waste box and accumulate near the vertically downward side
Solution Approach 1:
A support section is introduced as an intermediary component between the cutting blades and the waste box. This support section temporarily holds remnants during the cutting process and guides them to fall evenly into the waste box, preventing accumulation at the vertically downward side while maintaining complete cutting operation.
2Area of stationary object
If the waste box is placed shallow and close to the cutting area, then it saves space, but remnants come out of the waste box and may interfere with subsequent cutting processes
Solution Approach 1:
The support section acts as a mediator that extends over the waste box opening, creating a barrier that prevents remnants from escaping the waste box even when the box is shallow. This allows the waste box to be positioned close to the cutting area without compromising the stability of subsequent cutting operations.
3Quantity of substance
If remnants are accumulated near the vertically downward side of the other end portion, then they are stored in the waste box, but the collection frequency must be increased
Solution Approach 1:
The support section distributes remnants evenly across the entire width of the waste box by guiding them from different positions during the gradual cutting process. This even distribution maximizes the effective storage capacity of the waste box and reduces the frequency of collection operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The support section effectively directs remnants into the waste box, minimizing the risk of interference during cutting and reducing the frequency of collection, maintaining a cleaner cutting environment.
Implementation Method 1
The support section is located between the one end of the fixed blade and the other end in such a way as to be closer to a vertically downward side than the fixed blade, when the placement surface of the stage that is in a horizontal state faces a vertically upward side

AI summary
A sheet cutting device includes a stage including a placement surface on which a to-be-cut sheet is placed; a strip-shaped fixed blade that is provided in one end portion of the stage; a movable blade that works together with the fixed blade to cut the sheet placed on the placement surface of the stage gradually from one end portion of the sheet to a different one end portion; and a support section that is located between the one end of the fixed blade and the other end in such a way as to be closer to a vertically downward side than the fixed blade and be closer to a vertically upward side than a bottom surface of a waste box placed closer to the vertically downward side than the fixed blade, to temporarily support part of a remnant generated after cutting by the fixed and movable blades.
