Screwdriver RFID Tag Layout for Omnidirectional Reader Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screwdrivers with electronic tags face communication issues due to orientation and posture, leading to potential loss of connectivity with the reader, and may suffer from damage or increased size when the tag is not properly designed.
Innovation Solution
The screwdriver design includes an electronic tag attached to the attachment member along the circumferential direction, with a groove or accommodation space to ensure consistent communication, and uses a non-metallic spacer to prevent wave reflection, maintaining compact size and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic tag is provided continuously or intermittently along the circumferential direction, then communication with the reader is possible regardless of orientation and posture, but the size of the tool increases
Solution Approach 1:
The electronic tag is arranged circumferentially around the handle rather than linearly along the shaft, utilizing the radial dimension to achieve omnidirectional communication while maintaining a compact tool profile
Solution Approach 2:
The electronic tag is nested within a recess formed in the handle, allowing the tag to be positioned inside the handle structure rather than adding external volume, thus maintaining communication reliability without significantly increasing the overall tool size
2Reliability
If the electronic tag is attached to the attachment member, then the tag is protected from damage during work, but radio wave reflection occurs when the attachment member is made of metal
Solution Approach 1:
A non-metallic spacer is introduced between the electronic tag and the metal attachment member to prevent radio wave reflection. The spacer acts as an intermediary that blocks the harmful electromagnetic interaction while allowing the tag to remain securely mounted on the metal structure
Solution Approach 2:
The attachment member is constructed as a composite structure combining metal and non-metallic materials, where the metal provides structural strength and the non-metallic spacer prevents radio wave reflection, achieving both mechanical durability and communication stability
3Adaptability or versatility
If the groove is continuously provided over the entire circumference, then radio wave transmission in all directions is achieved, but the tool size increases
Solution Approach 1:
Instead of extending the groove linearly along the shaft, the groove is arranged circumferentially around the handle, utilizing the radial dimension to achieve omnidirectional radio wave transmission while maintaining a compact tool profile
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
Ensures reliable communication with the reader regardless of orientation and posture, prevents tag damage, and maintains a compact size while enhancing communication distance.
Implementation Method 1
an electronic tag attached to the attachment member, and provided continuously or intermittently along a circumferential direction... it is possible to communicate with a reader regardless of an orientation and a posture of the tool
Implementation Method 2
when the electronic tag is attached to the attachment member, a part of the radio wave transmitted from the electronic tag is reflected by the attachment member, so that the radio wave is canceled and weakened

AI summary
In order to enable communication with a reader regardless of an orientation and a posture of a tool, the tool includes: a handle to be gripped by an operator; a force application member provided on a distal end side of the handle; an attachment member provided on a rear end side of the handle; and an electronic tag attached to the attachment member or a rear end portion of the handle and continuously or intermittently provided along a circumferential direction.
