Single-Motor Saddle Stapler Layout for Driver and Clincher Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle binding staplers require separate motors for the driver and clincher units, leading to increased size, component count, and costs, making it structurally difficult to operate both with a single motor.
Innovation Solution
A stapler design that uses a single motor to operate both the driver and clincher units through a coupling and transmission system, allowing the driver and bending units to be positioned orthogonally and enabling a single motor to drive both units, with a sheet passing area open upstream and downstream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If separate motors are provided for driver and clincher units in a saddle binding stapler, then the driver and clincher can be positioned separately to ensure large sheet passing area, but the stapler size and component count increase
Solution Approach 1:
The patent merges the driver unit and clincher unit into a single integrated assembly where one motor drives both units through a shared transmission mechanism. The clincher unit is positioned to receive staple legs from the driver unit, and both units share common structural support and power transmission components, reducing the overall component count while maintaining the sheet passing area required for saddle binding.
2Ease of operation
If separate motors are provided for driver and clincher units, then each unit can be independently operated, but the manufacturing cost increases
Solution Approach 1:
The single motor in the patent is designed to perform multiple functions by driving both the driver unit and clincher unit through a transmission mechanism. This multi-functional approach eliminates the need for separate motors while maintaining the operational capabilities required for saddle binding, thereby reducing manufacturing costs without sacrificing operational effectiveness.
3Device complexity
If driver and clincher are disposed close to each other to enable single motor operation, then component count reduces, but sheet passing area becomes insufficient for saddle binding
Solution Approach 1:
The patent resolves the spatial conflict by arranging the driver unit and clincher unit in a vertical stacking configuration rather than horizontal placement. The clincher unit is positioned below the driver unit, utilizing the vertical dimension to accommodate both components while maintaining adequate sheet passing area in the horizontal plane required for saddle binding operations.

AI summary
A stapler for performing binding processing of binding a sheet with a staple, the stapler includes: a driver unit configured to drive the staple to the sheet; a bending unit configured to bend a staple leg of the staple that is driven by the driver unit and penetrates the sheet; a single motor configured to operate the driver unit and the bending unit; a coupling portion coupling the driver unit and the bending unit on one side in a direction orthogonal to a sheet passing direction of the sheet passing between the driver unit and the bending unit and along the sheet surface in the case of performing the binding processing; and a transmission unit configured to transmit a driving force of the motor to the driver unit and/or the bending unit via the coupling portion.
