Box Edge Stapler Double-Pull Mechanism for Iron Core Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional staplers for paper are inefficient for fixing box edges, leading to economic waste and aesthetic issues due to protruding iron core ends that can catch contents and detract from the box's appearance.
Innovation Solution
A stapler designed for box edges with a handle bar mechanism that minimizes iron core protrusion by using load bars, rotary gears, and pressing plates to press the iron core ends inward, eliminating the need for additional fasteners and allowing for easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional stapler with single handle bar pull is used, then the structure is simple, but the iron core end protrusion cannot be minimized
Solution Approach 1:
The patent implements a dynamic double-pulling mechanism where the handle bar performs two distinct pulling actions: first pulling to locate the iron core on the support plate, and second pulling to press the iron core end inward. This dynamic sequential operation transforms a static single-action mechanism into a dynamic two-stage process, achieving precise positioning and pressing without requiring complex additional components
Solution Approach 2:
The handling operation is segmented into two distinct phases: first pulling for location and second pulling for pressing. The mechanism divides the single handle bar operation into sequential functional stages, with each pull serving a specific purpose in the iron core positioning and pressing process, thereby achieving complex functionality through temporal segmentation of a single component
2Strength
If bolts and nuts are used to fix box edges, then the connection is strong, but economic efficiency decreases and assembly complexity increases
Solution Approach 1:
The patent extracts and eliminates the need for separate fastening components (bolts and nuts) by integrating the fixing function directly into the stapler mechanism. The iron core itself serves as both the fastening element and the structural component, removing the need for additional parts and simplifying the overall assembly process while maintaining connection strength
Solution Approach 2:
The patent merges the functions of the iron core with the fastening mechanism. Instead of using separate bolts and nuts, the iron core is directly pressed and fixed into the box edge, combining the structural support function and the fastening function into a single integrated component, thereby reducing part count and assembly complexity
3Device complexity
If iron core end is left protruding, then the structure is simple, but aesthetic appeal decreases and content catch occurs
Solution Approach 1:
The patent applies preliminary pressing action through the double-pulling mechanism that presses the iron core end inward before the box is fully assembled or before contents are placed. This preliminary action prevents the harmful effect of content catch by ensuring the iron core end is already positioned flush with the box edge, eliminating the need for post-assembly adjustments
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 stapler effectively minimizes iron core protrusion, preventing content catch and enhancing the aesthetic appeal of the box while providing economic efficiency by eliminating the need for bolts and nuts and allowing for easy replacement of damaged parts.
Implementation Method 1
a first pushing elastic member of which one side is connected to the iron core pushing member and the other side is connected to the fixing rod
Implementation Method 2
a second pushing elastic member disposed in the upper plate to be connected with one side of the iron core storage part
Implementation Method 3
rotary gears respectively disposed at both sides and engaging and rotating with the rack sliding vertically
Implementation Method 4
a rack disposed inside the iron core support plate and vertically sliding through a sliding pin connected to the sliding groove of the first load bar
Implementation Method 5
an iron core storage part of which an end portion is coupled with one side of the lower plate by a hinge, into which a plurality of iron cores are inserted

AI summary
The present invention relates to a stapler for box edges which fixes edge portions of a box, presses an end of an iron core, and doubly pulls a handle bar so as to minimize protrusion of the end of the iron core. The stapler includes a load bar and a push plate which can locate an iron core on an iron core support plate when the handle bar is pulled first and presses the end portions of the iron core inward when the handle bar is pulled second.
