Stapler Stopping Plate Recess Reduces Staple Rebound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional staplers fail to securely fix wires or pipes, leading to rebound issues that can cause electric leakage, signal transmission problems, or fluid leakage due to inadequate staple fixation.
Innovation Solution
A stapler design featuring a main body with a trigger, striking mechanism, and stopping plate, where the trigger switches between release and accumulating modes to control the striker's movement, and a concave face with a recessed stopping plate reduces staple rebound by guiding and abutting the staple unit, ensuring precise striking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional stapler is used to strike staples, then the stapler can fix wires or pipes, but the staples rebound and break the wires or pipes down
Solution Approach 1:
The patent applies preliminary anti-action by introducing a stopping plate with a recess that预先 (in advance) counteracts the rebound motion of the staple. The recess structure is designed to receive and limit the staple's backward movement after striking, preventing the harmful rebound effect before it can damage the wire or pipe.
Solution Approach 2:
The stopping plate serves as an intermediary element between the staple and the target object. It mediates the interaction by providing a controlled stopping point for the staple, allowing the staple to be driven in firmly without excessive force that would cause rebound and damage to the wire or pipe.
2Strength
If the staple is struck with sufficient force to fix firmly, then the fixation is strong, but the staple rebounds and breaks the wires or pipes
Solution Approach 1:
The recess in the stopping plate is designed to anticipate and counteract the rebound force. By providing a pre-calculated stopping depth and direction, the system allows strong initial striking force to achieve firm fixation while the recess prevents the harmful rebound that would otherwise damage the wire or pipe.
Solution Approach 2:
The patent changes the geometric parameters of the stopping plate, specifically incorporating a recess with specific dimensions and orientation. This parameter change allows the system to tolerate higher striking forces for stronger fixation while the recess geometry controls the staple's final position and prevents excessive penetration or rebound that would damage the target object.

AI summary
The stapler includes a main body, a trigger, a striking mechanism, and a stopping plate. The main body has an outlet at a first end portion. The trigger is pivotally connected to the main body with an end, and the other end extends toward the first end portion for being pressed toward the main body. The striking mechanism includes a striker at the first end portion and a releasing unit for releasing the striker. The trigger switches the releasing unit between a release mode and an accumulating mode so that the striker can move toward the outlet. The striker has a concave face facing the outlet for striking a staple unit. The stopping plate is disposed on the first end portion and is for the staple unit to abut against horizontally. The stopping plate has at least one recess at an end thereof facing the outlet.
