Stapler Striker Inclined Bottom Face 3-15 Degrees
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional staplers face inefficiencies due to inadequate elastic force in the magazine, leading to nail misalignment and jamming issues when striking staples, resulting in reduced performance and component wear.
Innovation Solution
The stapler design features a striker with an inclined bottom face (3-15 degrees) and a horizontal magazine that pushes staples out, combined with a blocking structure including an elastic element to ensure proper staple alignment and force application, preventing jamming and improving striking efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the elastic element in the magazine has strong elasticity to push nails forward, then the nails are pushed out more effectively, but the first nail lacks sufficient elastic force causing the lower end to move backward and become inclined, resulting in striking failures
Solution Approach 1:
The patent changes the geometric parameters of the striker by introducing an inclined bottom face with a specific angle range (5-15 degrees). This parameter modification allows the striker to apply force at an optimal angle that compensates for the nail's backward movement tendency, ensuring reliable striking even when the elastic force causes nail inclination.
Solution Approach 2:
The striker's bottom face is designed with asymmetric inclination rather than a flat or symmetric shape. This asymmetric geometry enables the striker to effectively engage with the inclined nail and apply corrective force during the striking process, resolving the alignment issues caused by strong elastic pushing.
2Productivity
If the staple is struck out with strong force, then the striking efficiency is improved, but the staple may jam or pivot, making it unable to be struck out successfully
Solution Approach 1:
The patent modifies the striking mechanism by changing the angle of force application through the inclined bottom face of the striker. This parameter change allows the force to be applied in a direction that guides the staple forward without causing pivoting or jamming, maintaining high striking efficiency while eliminating harmful side effects.
3Ease of operation
If the nail is hit by the striker with conventional alignment, then the striking process is simple, but the nail becomes inclined and fails to be struck out successfully, reducing working efficiency and causing component wear
Solution Approach 1:
The patent introduces a parameter change in the striker's geometry (inclined bottom face angle of 5-15 degrees) that automatically compensates for nail inclination during the striking process. This maintains the simplicity of operation while dramatically improving working efficiency and reducing component wear.
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
This design enhances the striking efficiency by ensuring the staple is aligned and receives consistent force, reducing failures and wear on components, thereby improving the stapler's operational efficiency and reliability.
Implementation Method 1
The conventional magazine has an elastic element to push the nails frontward, but the elasticity can not be too strong to result the failure of striking.

AI summary
A stapler includes a main body, a magazine, a striker, and a driving portion. The main body encloses a receiving space and has an opening at the bottom of the front end thereof. The opening communicates with the receiving space. The magazine is arranged in the main body for receiving staples. The striker is arranged at the front end of the main body and is linearly slidable above the opening vertically. The driving portion is disposed on the main body and is connected to the striker to drive it to move downward to strike the staple out. The striker has a bottom face oriented frontward and downward so that an angle ranged from 3-15 degrees is defined between the bottom face and the horizontal plane.
