Electric Stapler Handle Power Gating for Extended Battery Operation

Solution Overview

Problem

The use of high-capacity battery packs in electric staplers increases the volume, weight, and storage space requirements, leading to poor user experience and operational challenges.

Innovation Solution

A low-power-consuming control method and device for the electric stapler handle that reduces power consumption by controlling the driving and Hall power supply networks to enter a dormant state when not in use, using a timer to detect inactivity and triggering the handle controller to enter a low-power mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a high-capacity battery pack is used to ensure the electric stapler can work for a long time, then the duration of action is improved, but the volume, weight and storage space increase

Engineering Contradiction:

Improveworking durationVSAvoidbattery pack weight

Core Design Contradiction:

Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The patent implements periodic action by introducing dormant periods where power supply is interrupted to non-essential circuits (Hall sensor circuit, display circuit, etc.) while maintaining power to essential circuits. This creates a rhythm of active and dormant states, reducing average power consumption without compromising the ability to work when needed, thereby extending working duration without increasing battery capacity.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies dynamics by making the power consumption state variable and adaptable. The control circuit dynamically adjusts power distribution based on operational needs, switching between full-power mode and dormant mode. This dynamic power management allows the system to optimize between working duration and battery capacity requirements.

Inventive Principle:

Principle #15Dynamics

3Use of energy by moving object

If the electric handle enters low-power mode by stopping power supply to driving and Hall power supply networks, then power consumption is reduced, but the ability to respond to user input may be affected

Engineering Contradiction:

Improvepower consumptionVSAvoidresponse to user input

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent applies segmentation by dividing the power supply network into distinct segments: essential circuits (motor control, basic input detection) that remain powered, and non-essential circuits (Hall sensor, display, auxiliary functions) that can be powered down. This segmentation allows the system to reduce overall power consumption while maintaining responsiveness to essential user inputs during dormant periods.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements feedback mechanisms where the control circuit continuously monitors for user input signals. When input is detected during dormant period, the system receives feedback and transitions from low-power mode to active mode, ensuring that ease of operation is maintained despite reduced power consumption during inactivity.

Inventive Principle:

Principle #23Feedback

AI summary

An electric stapler, and a low-power-consuming control method and device for a handle thereof, and a storage medium. The control method comprises the following steps: when a battery pack is mounted in a battery compartment, starting timing, detecting whether an electric handle receives an operation instruction, and controlling an adapter to recognize a working head (S101); and if the timing time reaches a first preset time, the electric handle does not receive an operation instruction, and the adapter does not recognize a working head, controlling a drive power supply network and a Hall power supply network of an electric stapler to stop power supply output, and triggering a handle controller to enter a dormant state, so that the electric handle enters a low-power-consuming mode (S102). Thus, the power consumption of the electric handle can be minimized, and the power consumption generated when the electric handle is not used can be reduced, so that the remaining electric quantity is left as much as possible in cases where the battery capacity does not change, so as to ensure that the electric handle can operate for a long time.
