Tool Holder Data Carrier Sleeve for Balanced RFID Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The secure and permanent attachment of data carriers to tool holders is challenging due to issues with positioning, shielding, and adhesive detachment, leading to potential risks and fluctuations in data carrier reading accuracy.
Innovation Solution
A sleeve-shaped base body with radially inward and outward projections provides a stable and quick attachment mechanism, allowing the data carrier to be securely held within a tool holder, even at high speeds, and is designed to be easily readable, with optional elastic features and a spacer element for enhanced positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the data carrier is mounted further away from the axis of rotation on the outside of the holder, then the data reading is facilitated, but the tool holder's balance is affected
Solution Approach 1:
The invention transitions from radial mounting (affecting balance) to axial mounting within the bore (preserving balance). The data carrier is mounted in the axial direction within the tool holder's bore, eliminating the radial offset that causes balance issues while still allowing data reading through the holder wall.
Solution Approach 2:
The invention introduces a specialized mounting device as an intermediary component that bridges the data carrier and the tool holder. This device includes a body with a data carrier holder and fastening elements that secure the carrier within the bore, enabling stable axial mounting while maintaining balance.
2Stability of the object's composition
If the data carrier is mounted close to the axis of rotation within the tool holder, then the tool holder's balance is maintained, but the data carrier becomes unreadable due to shielding
Solution Approach 1:
The mounting device serves as an intermediary that positions the data carrier optimally within the bore - close enough to the axis for balance but with controlled offset and orientation to enable reading. The device includes positioning elements that ensure the carrier's antenna is oriented toward the reading device while maintaining rotational balance.
Solution Approach 2:
The invention applies local quality by creating a specialized mounting environment within the bore that differs from the bulk holder material. The mounting device provides localized structural support and positioning features that enable reading capability at specific locations without affecting the overall holder balance.
3Ease of manufacture
If adhesive bond is used to attach the data carrier, then the attachment process is simple, but the bond loosens over the tool holder's lifespan causing ejection
Solution Approach 1:
The invention replaces the chemical adhesive bonding system with a mechanical fastening system. The mounting device includes fastening elements such as clips, lugs, or interference-fit features that mechanically secure the data carrier to the holder, eliminating the reliability issues of adhesive degradation while maintaining manufacturing simplicity.
Solution Approach 2:
The mounting device incorporates dynamic fastening features that can accommodate minor dimensional variations and thermal expansion/contraction cycles. The fastening elements are designed with appropriate clearance and elasticity to maintain secure attachment under varying operational conditions throughout the tool holder's lifespan.
4Adaptability or versatility
If adhesive bond quality varies depending on personnel and care, then manufacturing flexibility is maintained, but attachment reliability fluctuates
Solution Approach 1:
The invention replaces the skill-dependent adhesive application process with a mechanical fastening system that provides consistent attachment quality regardless of operator skill. The mounting device features standardized fastening elements that ensure uniform attachment reliability across all manufacturing operations while maintaining flexibility in implementation approaches.
