Staple Gun With Press Piece For Secure Wall Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional staple guns fail to securely fasten papers to walls due to the small contact area between staples and papers, making them susceptible to being dislodged by wind.
Innovation Solution
A staple gun design that simultaneously drives out a staple and a press piece, with a casing unit, striker unit, handle unit, and loading unit, including a staple holder and press piece pushing subunits, to provide a larger contact area and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional staple guns are used to fasten papers to walls, then the stapling process is simple and quick, but the contact area between staples and papers is small causing corners to be easily removed by wind
Solution Approach 1:
The patent combines a staple (for piercing) and a press piece (for pressing) into a single fastening unit. The press piece is integrated with the staple such that when the staple is driven through the paper, the press piece simultaneously contacts the paper surface, creating a combined piercing-and-pressing action that increases contact area while maintaining fastening reliability
Solution Approach 2:
The fastening system is segmented into two functional components: the staple for piercing the paper and the press piece for applying pressure. This segmentation allows each component to perform its specific function optimally while working together to solve the contradiction between simple operation and reliable fastening with increased contact area
2Reliability
If only staples are used for fastening, then the device structure is simple, but the holding capacity is insufficient against wind
Solution Approach 1:
The patent merges the staple and press piece into a single integrated fastening assembly that operates as one unit. This combining approach increases holding capacity by adding the pressing function to the existing staple structure, while the integration ensures that both components are driven simultaneously through the paper in a single operation, minimizing the increase in device complexity
3Object-affected harmful factors
If a press piece is added to increase contact area, then wind resistance improves, but the loading and striking mechanisms become more complex
Solution Approach 1:
The press piece is pre-positioned on the staple during the loading process, so that when the user pulls the trigger, both the staple and press piece are already in the correct positions for simultaneous driving. This preliminary arrangement of components simplifies the loading mechanism while ensuring that the press piece is ready to provide wind resistance protection
Solution Approach 2:
The loading mechanism is designed to load both the staple and press piece as a single integrated unit. The press piece is retained on the staple through a retention structure that allows both components to be driven simultaneously through the paper in one triggering action, thereby increasing wind resistance without proportionally increasing device complexity
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 design enhances the holding capacity of papers on walls by providing a larger contact area, reducing the likelihood of corners being removed by wind and ensuring stable fastening.
Implementation Method 1
The staple spring has opposite ends that are respectively connected to the staple pusher and the connecting member of the staple holder, and extends around the pulley member such that the staple spring exerts a biasing force onto the staple pusher
Implementation Method 2
The press piece spring has opposite ends that are respectively connected to the press piece pusher and the connecting member of the staple holder, and extends around the pulley member such that the press piece spring exerts a biasing force onto the press piece pusher
Implementation Method 3
The striker unit is movably mounted to the casing unit, and is adapted for striking the frontmost staple and the frontmost press piece out of the casing unit through the exit opening
