Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electric staplers often get stuck, making it difficult to remove staples without damaging the binding mechanism, which can lead to deformation or complete destruction of the stapler.

Innovation Solution

A stuck staple processing mechanism is introduced, featuring a pop-up mechanism with a side wheel, lever, and pressing pin, allowing the staple channel to be reversed and unlocked for easy removal of stuck staples by rotating the side wheel in the opposite direction, facilitated by a controller and transmission mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users remove stuck staples themselves by forcing the staple channel out, then stuck staples can be removed, but the upper blade deforms and the binding mechanism is destroyed

Engineering Contradiction:

Improveease of staple removalVSAvoidintegrity of binding mechanism

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Instead of pulling the staple channel out in the normal direction, the invention reverses the rotation direction of the driving mechanism to drive the staple channel assembly to move in the opposite direction, thereby unlocking and ejecting the stuck staple. This reverse action avoids forcing the staple channel out and protects the binding mechanism from damage.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The electric stapler automatically detects the stuck staple condition and executes the reverse rotation process to eject the stuck staple by itself, without requiring manual intervention that could damage the binding mechanism. The system serves itself by autonomously resolving the sticking problem.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If the staple channel is forcibly pulled out to remove stuck staples, then staples can be removed, but the electric stapler may not be used anymore

Engineering Contradiction:

Improvestaple removal capabilityVSAvoidusability of electric stapler

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention uses reverse rotation of the driving mechanism to unlock and eject the staple channel assembly, allowing stuck staple removal without forcing the staple channel out. This preserves the stapler's functionality and ensures it remains usable for future operations.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If a pop-up mechanism is added to enable staple channel ejection, then stuck staples can be removed conveniently, but the device complexity increases

Engineering Contradiction:

Improvestaple removal convenienceVSAvoidcomplexity of pop-up mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The invention merges the pop-up mechanism with the existing driving mechanism by using the same motor and transmission components. The driving mechanism can rotate in both forward and reverse directions, with reverse rotation driving the staple channel assembly to move and eject stuck staples. This integration avoids adding separate complex mechanisms while achieving the desired functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The driving mechanism is designed to perform multiple functions: forward rotation for normal staple driving and reverse rotation for staple channel ejection and stuck staple removal. This multi-functionality eliminates the need for separate dedicated mechanisms, reducing overall device complexity while maintaining ease of operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The disclosure discloses a stuck staple processing mechanism of an electric stapler and the electric stapler. The stuck staple processing mechanism of the electric stapler includes a driving mechanism, a transmission mechanism, a pop-up staple channel assembly, a controller and a pop-up mechanism. The transmission mechanism is connected with a pop-up switch of the pop-up staple channel assembly through the pop-up mechanism. When the controller controls the driving mechanism to rotate along a staple placing direction, the pop-up mechanism does not make the staple channel assembly act. When the controller controls the driving mechanism to rotate in an opposite direction of staple placing, the transmission mechanism makes the pop-up switch act through the pop-up mechanism to pop up a staple channel of the staple channel assembly, so as to facilitate a removal of a stuck staple.
