Solution Overview

Problem

Conventional staplers using nonmetal staples face stability issues due to the protrusion of the operation handle, requiring a support leg that increases the device's size, while also needing to be compact for easy use in narrow spaces.

Innovation Solution

A stapler design where the operation handle extends from one end of the stapler body to the other, allowing the counterforce to be received at the rear portion, minimizing the stapler's size and eliminating the need for a support leg by distributing the force effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operation handle is inclined to the front upper side, then the handle operation is facilitated, but the stapler body becomes unstable and requires a support leg that increases the device size

Engineering Contradiction:
Improvehandle operationVSAvoidstapler body stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The operation handle is repositioned from an inclined front upper position to a rear upper position, changing the spatial dimension of force application. This dimensional change allows the counterforce to be received at the rear portion of the stapler body, eliminating the need for a forward-protruding support leg and thereby maintaining compactness while ensuring stability during operation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If a support leg is added to prevent overturning, then the stapler body stability is improved, but the device size increases

Engineering Contradiction:
Improvestapler body stabilityVSAvoidstapler body size
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The support leg component is completely removed from the stapler design. Instead of adding a support leg to the front portion, the invention extracts this unnecessary component by repositioning the operation handle to the rear upper position, allowing the stapler body to maintain stability without the extra structural element, thereby reducing overall device size

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the operation handle extends to the front upper side, then the pressing operation is enabled, but the stapler cannot be used in narrow spaces due to increased size

Engineering Contradiction:
Improvepressing operationVSAvoidstapler footprint
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The operation handle is repositioned from a front upper position to a rear upper position, changing the spatial arrangement of the stapler. This dimensional reconfiguration allows the stapler to have a more compact footprint, enabling it to be used in narrow spaces while still facilitating the pressing operation through the rear-positioned handle

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

To minimize a stapler body largely, a stapler includes a stapler body and an operation handle. the stapler body provides a sheet placement part on one end portion of the stapler body and includes a penetration mechanism which forms a through hole in a sheet placed on the sheet placement part to allow a nonmetal staple supplied from the other end portion of the stapler body to penetrate through the through hole. The operation handle is connected with the one end portion and includes a handle operation part which is operable to be pressed. The penetration mechanism is configured to form the through hole in the sheet in conjunction with a pressing operation of the operation handle so as to allow the nonmetal staple to penetrate therein. The handle operation part is formed to extend from the one end portion toward the other end portion.
