Solution Overview

Problem

Existing electric tool systems face inefficiencies due to potential failures in wireless communication with a management system, leading to delays and reduced work efficiency when screw fastening operations are interrupted.

Innovation Solution

An electric tool system that includes a management system capable of transmitting setting information for multiple tasks during a single communication session, allowing the tool to perform tasks based on previously received data even if communication is interrupted, and resumes work upon reestablishing connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication is established between the electric tool and the management system, then the tool can receive screw fastening information remotely, but the tool may fail to receive information due to communication environment issues, causing work interruptions

Engineering Contradiction:
Improvewireless communication capabilityVSAvoidinformation reception reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The management system transmits screw fastening information for multiple tasks in advance during a single communication session before work begins. The electric tool stores this information locally in its storage unit, so that even if communication fails during operation, the tool can continue executing tasks using the pre-received information without interruption.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the management system transmits setting information for each task separately, then communication can be simple, but work efficiency declines due to repeated communication needs and potential interruptions

Engineering Contradiction:
Improvework efficiencyVSAvoidcommunication time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The management system merges multiple task setting information transmissions into a single communication session. Instead of transmitting information for each task separately, the system sends batched information containing settings for multiple tasks in one go, reducing communication frequency and time while maintaining complete task information availability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The management system performs preliminary transmission of all necessary setting information for multiple tasks before the electric tool begins operation. This advance batching allows the tool to store comprehensive task information locally, eliminating the need for repeated communication during work execution and minimizing communication time loss.

Inventive Principle:
Principle #10Preliminary action

AI summary

An object of the present disclosure is to reduce the chances of causing a decline in the efficiency of work to be done using an electric tool. An electric tool system (1) includes an electric tool (2) and a management system (3). The electric tool (2) includes a first communications unit (25) that establishes wireless communication. The electric tool (2) is used to do work on a work target. The management system (3) includes a second communications unit (41) that communicates wirelessly with the first communications unit (25) of the electric tool (2). The management system (3) makes the second communications unit (41) transmit, during a single communication session with the first communications unit (25), setting information about multiple tasks of the work to the first communications unit (25).
