Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IC tag mounting structures for bolts are costly due to time-consuming manufacturing processes and have restrictions on mounting direction, limiting their productivity and versatility.
Innovation Solution
A mounting member with an IC tag featuring a metal shaft, a disk-shaped base, and a resin head portion that seals the IC tag, allowing for easy manufacturing and flexible mounting directions, with features like a folded-back portion and knurl pattern for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the IC tag is incorporated in the head portion of the bolt using the conventional method with housing portion, filler, and resin coating layer, then the IC tag is protected and sealed, but the manufacturing process becomes time-consuming and costly
Solution Approach 1:
The patent combines the sealing function and IC tag housing into a single integrated resin head portion. The resin head is molded to directly cover and seal the IC tag mounted on the base portion, eliminating the need for separate housing portions, fillers, and lid attachments. This integration maintains reliable sealing while dramatically simplifying the manufacturing process.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components from the conventional structure. By removing the housing portion, filler material, and separate lid, the design achieves sealing through the resin head alone, which is molded directly over the IC tag, thus reducing manufacturing steps and costs.
2Strength
If the bolt is made of metal to ensure strength and durability, then the mounting member is robust, but communication with the IC tag requires specific mounting direction due to metal interference
Solution Approach 1:
The patent uses a composite structure where the shaft portion is made of metal for strength and durability, while the head portion is made of resin for electromagnetic transparency. This material combination allows the metal shaft to provide mechanical strength while the resin head enables unrestricted mounting directions by allowing electromagnetic waves to pass through for IC tag communication.
Solution Approach 2:
The patent divides the bolt into two functional segments: a metal shaft portion for mechanical strength and a resin head portion for electromagnetic compatibility. This segmentation allows each part to perform its optimal function without interfering with the other, enabling both robustness and mounting flexibility.
3Reliability
If multiple components (housing portion, filler, lid, resin coating) are used to seal the IC tag, then the sealing is reliable, but the number of manufacturing steps increases
Solution Approach 1:
The patent merges multiple sealing components into a single integrated resin head portion. The resin head is molded to directly cover the IC tag and provides sealing through its own structure, eliminating the need for separate housing portions, fillers, lids, and resin coating layers, thus reducing component count while maintaining sealing reliability.

AI summary
Provided is a mounting member with an IC tag, the mounting member being easily manufactured and configured so as to not have constraints in terms of attachment orientation. The mounting member with an IC tag is provided with: a shaft-shaped section (1) having a shaft-shaped insert part (11) and a base part (12) which is formed by one end section of the insert part (11) protruding in the width direction; an IC tag (2) fixed to a surface (123) of the base part (12); and a resin head part (3) which is molded to at least the surface (123) side of the base part (12) so as to seal the IC tag(2). Male threads are preferably formed on the insert part (11).
