Stapler Cartridge Lever Mechanism for Multi-Direction Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stapler cartridges are difficult to remove due to operational limitations, leading to potential damage or dropping during removal, and lack versatility in removal methods.
Innovation Solution
A cartridge design featuring a lever that can be displaced in multiple directions to release a fixing mechanism, allowing for various operability and preventing erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-direction removal mechanism is used, then the structure is simple, but the operability is limited and erroneous operations may occur
Solution Approach 1:
The lever is designed to accept multiple input directions (rotational movement in either direction, or pulling motion) and convert them all into the same functional output: releasing the fixing portion. This multi-functional design allows users to remove the cartridge through various operation methods, significantly improving ease of operation while maintaining a relatively simple overall structure.
Solution Approach 2:
The lever mechanism incorporates dynamic response to different input forces. Whether the user rotates the lever clockwise, counterclockwise, or pulls it outward, the mechanism dynamically adapts by engaging the fixing portion release in any of these directions. This dynamic characteristic allows the system to respond flexibly to various user operations without requiring complex control logic.
2Reliability
If a fixed single-direction mechanism is used, then manufacturing is simple, but the risk of cartridge damage during removal increases
Solution Approach 1:
The fixing portion and lever are designed with multi-directional release capability, where the fixing portion can be disengaged regardless of whether the user rotates the lever in either direction or pulls it outward. This universal release mechanism ensures reliable cartridge removal without damage, while the straightforward mechanical design keeps manufacturing complexity low.
3Ease of operation
If multiple removal directions are enabled, then operability is improved, but the mechanism becomes more complex
Solution Approach 1:
The lever mechanism is segmented into distinct functional zones: the lever body that accepts multiple input directions, the connection point to the fixing portion, and the release mechanism itself. This segmentation allows each component to perform its specific function simply, while collectively providing complex multi-directional operability. The fixing portion is also segmented with features that respond to different lever movements independently.

AI summary
There is provided a cartridge to be mounted on a stapler, and a stapler. The cartridge includes: a cartridge main body configured to accommodate a staple; a lever attached to the cartridge main body to be displaceable with respect to the cartridge main body; and a fixing portion for fixing the cartridge to the stapler when the cartridge is loaded on the stapler. The fixing portion is located at a first position in a fixed state where the cartridge is fixed to the stapler, and is located at a second position in a released state where the fixed state is released. The lever has a moving portion that moves the fixing portion to the second position when the lever is displaced in a first direction and a second direction with respect to the cartridge main body.
