Motion Sensor Standby Wake-Up for Driving Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for incorporating fastening elements into underground surfaces require users to manually check if the device is in operating or standby mode, wasting time and energy, especially when transitioning from standby to operational mode.
Innovation Solution
A device equipped with a trigger switch and electronic control device that generates an alarm signal and automatically transitions from standby to operational mode upon user movement detection, using a movement sensor to ensure efficient energy transfer and operation readiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the device automatically enters standby mode after a predetermined period of non-use, then energy consumption is reduced, but the device requires manual switching and mode checking which increases operation time
Solution Approach 1:
The motion sensor detects user movement and triggers the control unit to switch from standby mode to operating mode before the user actually needs to operate the device. This preliminary detection and automatic mode switching eliminates the need for manual mode checking and switching, resolving the contradiction between energy-saving standby mode and quick operational readiness
Solution Approach 2:
The device automatically monitors its own operational state through the motion sensor and control unit, detecting when the user picks up or moves the device and autonomously switching modes without requiring user intervention. This self-service capability eliminates manual mode switching while maintaining energy efficiency during non-use periods
2Loss of information
If the user must test whether the device is in operating or standby mode by repeatedly driving the fastener in, then mode status can be determined, but this increases operation time and energy consumption
Solution Approach 1:
The motion sensor provides continuous feedback about device movement to the control unit, which automatically adjusts the operational mode based on detected user actions. This feedback mechanism provides real-time mode status information without requiring the user to test the device, eliminating both the information gap and the time/energy waste of repeated testing
Solution Approach 2:
The patent replaces the mechanical testing method (repeatedly driving fasteners to check mode status) with an electronic motion detection system. The motion sensor and control unit electronically detect and respond to user handling, substituting the wasteful mechanical trial-and-error approach with an intelligent electronic system that provides immediate mode status information
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 solution simplifies device operation by automatically switching from standby to operational mode upon user movement, ensuring quick readiness and reducing energy consumption, allowing for immediate use without manual switching.
Implementation Method 1
a motion sensor, which generates a wake-up signal when the device is moved by the user in a predetermined manner
Implementation Method 2
a spring is first tensioned. During the driving process, the spring then releases its tension energy abruptly to the piston, accelerating it towards the fastener
Implementation Method 3
an energy transfer device for transferring energy from an electrical energy source to the mechanical energy storage device

AI summary
The invention relates to an apparatus for driving a fastening element into a substrate, having a trigger switch that is actuated by a user of the apparatus and, when the trigger switch is actuated, generates a trigger signal, a motion sensor which, in the event of a predetermined movement of the apparatus by the user, generates a wake-up signal, and an electronic control device which, in an operating mode, is able to set the apparatus into a state ready for driving, in which a trigger signal from the trigger switch triggers an operation of driving a fastening element into a substrate, and which, in a standby mode, is able to receive a wake-up signal from the motion sensor and, upon receiving a wake-up signal, to switch from the standby mode into the operating mode.
