Clamping Bolt RFID Attachment Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clamping bolts cannot be identified independently of their position without altering their function, as integrating a RFID transponder into a conductive metal bolt would shield radio waves, and mounting becomes cumbersome when trying to access the screw.
Innovation Solution
A plastic attachment with a through opening and a receptacle region houses a RFID transponder, allowing for identification without changing the bolt's shape or mechanical function, using a non-conductive material that doesn't interfere with radio waves and includes a filling material for protection and a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a RFID transponder is integrated into the base body of a clamping bolt, then identification capability is improved, but the conductive metal material shields radio waves making integration impossible
Solution Approach 1:
The clamping bolt is divided into two separate components: the metal clamping bolt body and a separate attachment piece containing the RFID transponder. This segmentation allows the RFID functionality to be added without modifying the metal bolt, avoiding the radio wave shielding problem while maintaining identification capability.
Solution Approach 2:
A non-conductive attachment piece serves as an intermediary carrier for the RFID transponder. This intermediary component is attached to the metal clamping bolt, providing the identification function without the metal itself interfering with radio waves.
2Loss of information
If the clamping bolt shape and material are changed to accommodate RFID transponder, then identification capability is improved, but the mechanical function and shape of the clamping bolt are altered
Solution Approach 1:
The identification function is segmented into a separate attachment piece rather than being integrated into the clamping bolt body. This allows the bolt to maintain its original shape and mechanical properties while the attachment provides RFID functionality.
Solution Approach 2:
The attachment piece serves multiple functions: it provides the RFID transponder for identification and simultaneously maintains the clamping bolt's original shape and mechanical function. This multi-functionality approach adds identification capability without compromising the bolt's primary function.
3Loss of information
If a data carrier is clamped into the middle of the clamping bolt, then RFID functionality is added, but access to the screw is prevented increasing mounting effort
Solution Approach 1:
The attachment piece with RFID transponder is designed as a separate component that attaches to the clamping bolt without interfering with the through-opening or screw access. This segmentation allows independent access to both the RFID functionality and the mounting screw.
Solution Approach 2:
The attachment piece is positioned on the outer surface of the clamping bolt rather than being inserted into the through-opening. This dimensional change allows the screw to access the through-opening from the opposite side without obstruction, maintaining ease of mounting while adding RFID functionality.

AI summary
An attachment for a clamping bolt has a base body and an opening which passes through the base body. Around the through-going opening runs a contact face which is positioned orthogonally on the longitudinal axis of the through-going opening and which is configured to make contact with the clamping bolt. A receptacle region runs around the through-going opening in the basic body, between the through-going opening and the contact face. An RFID transponder is arranged in the receptacle region. The clamping bolt has a circular-cylinder-shaped clamping region. A first boundary region and a second boundary region bound the clamping region along the longitudinal axis of the clamping bolt Each boundary region has a larger external diameter than the clamping region. The attachment is arranged on the first boundary region. A through-going opening runs along the longitudinal axis of the clamping bolt.
