Stapler Detachable Cut Staple Storage Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing electric staplers, the productivity of binding sheets is reduced due to the need to move the stapler to a specific position for cut staple recovery, and there is a risk of staples leaking into the post-processing apparatus, with limited storage capacity and inability to detect full staple quantities.
Innovation Solution
A stapler with a detachable cut staple storage unit that allows staple storage and detection, enabling recovery without moving the stapler and preventing staple leakage, by integrating a cut staple quantity detection system and a discharge unit that guides cut staples to the storage unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cut staple storage unit is provided on the post-processing apparatus side and the stapler is moved to discharge cut staples, then the cut staple can be recovered, but the productivity of binding decreases due to the need to move the stapler
Solution Approach 1:
The cut staple storage function is segmented from the post-processing apparatus and integrated into the stapler as a detachable storage unit. This allows the stapler to independently store cut staples without requiring movement to a separate storage location, thereby maintaining binding productivity while ensuring reliable cut staple recovery.
Solution Approach 2:
The stapler is equipped with self-service capability to store its own cut staples through the detachable storage unit integrated into its structure. This eliminates the need for external post-processing apparatus intervention in the cut staple recovery process, allowing continuous operation without productivity loss.
2Reliability
If the stapler is moved to the position of the cut staple storage unit, then cut staple can be discharged, but there is a possibility that cut staple may leak into the post-processing apparatus
Solution Approach 1:
The cut staple storage unit is designed as a detachable component that can be removed from the stapler. This extraction capability allows complete removal of cut staples from the stapler without any risk of leakage into the post-processing apparatus, while maintaining reliable discharge functionality when attached.
Solution Approach 2:
The detachable storage unit allows cut staples to be completely removed from the stapler before any potential leakage can occur. This preliminary action of complete discharge eliminates the harmful effect of staple leakage into the post-processing apparatus.
3Reliability
If the cut staple storage unit is provided in the staple cartridge, then cut staple can be stored, but the quantity of cut staple that can be stored decreases
Solution Approach 1:
The cut staple storage unit is segmented as a separate detachable component rather than being integrated within the limited space of the staple cartridge. This segmentation allows for a larger storage capacity dedicated solely to cut staples, independent of the staple cartridge's internal volume constraints.
Solution Approach 2:
The cut staple storage unit is positioned in a different spatial dimension relative to the staple cartridge, attached to the stapler's exterior or side structure rather than occupying internal cartridge space. This dimensional change enables increased storage capacity without compromising staple cartridge functionality.
4Reliability
If the cut staple storage unit is provided in the staple cartridge, then cut staple can be stored, but it is necessary to recover cut staple before the staple in the staple cartridge disappears
Solution Approach 1:
The cut staple storage unit is segmented as a separate detachable component with independent capacity from the staple cartridge. This allows the staple cartridge to be fully utilized for binding operations without interruption for cut staple recovery, maintaining binding continuity and productivity.
Solution Approach 2:
The detachable storage unit serves as an independent copy of the storage function, separate from the staple cartridge. This independence allows simultaneous operation of staple consumption and cut staple storage without interference, enabling continuous binding productivity.

AI summary
A stapler includes a staple cartridge in which a staple is stored, a storage unit to which the staple cartridge is detachably attached, a staple ejecting unit which ejects the staple to penetrate a paper sheet, a cutting unit which cuts a staple leg of the staple penetrating the paper sheet, a binding unit which bends the staple leg of the staple penetrating the paper sheet to bind the paper sheet, a cut staple storage unit which stores a cut staple that is cut by the cutting unit, a cut staple quantity detection unit which detects a quantity of the cut staple stored in the cut staple storage unit, and a discharge unit through which the cutting unit and the cut staple storage unit communicate with each other to guide the cut staple to the cut staple storage unit. The cut staple storage unit is attachable to and detachable from the stapler.
