RFID Reader Isolation in Printing Device via Movable Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing devices with integrated RFID readers are susceptible to external forces, such as those experienced during a fall, which can propagate through the device and affect the antenna, compromising its functionality.
Innovation Solution
A printing device design featuring a first member and a second member with a movable configuration, where the RFID reader is positioned on the second member, allowing it to be isolated from external forces by indirect connection through a base member, and incorporating a receiving portion with a holder for consumable goods that retains an RFID tag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the RFID reader is integrated into the printing device with direct connection to the housing, then the device structure is simplified, but the RFID reader becomes susceptible to external forces such as impacts and drops
Solution Approach 1:
The printing device is divided into two separate members: a first member (housing) that receives the holder, and a second member (movable component) that carries the RFID reader. This segmentation isolates the RFID reader from the housing structure, preventing external forces applied to the housing from being transmitted to the RFID reader, thus resolving the contradiction between structural simplicity and component reliability.
Solution Approach 2:
A movable second member acts as an intermediary between the housing and the RFID reader. This intermediate component absorbs and isolates external forces, allowing the RFID reader to remain protected while still enabling functional interaction with the holder through the movable interface.
2Reliability
If the RFID reader is positioned on a movable second member isolated from the housing, then the RFID reader is protected from external forces, but the device structure becomes more complex
Solution Approach 1:
The second member is designed to be movable relative to the first member, allowing dynamic adjustment of the RFID reader's position. This dynamic configuration enables the system to maintain protection against external forces while adapting to different operational states, balancing reliability improvements with structural complexity through functional mobility rather than rigid isolation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively isolates the RFID reader from external forces, ensuring its functionality remains unaffected by impacts or drops, and allows for the use of various tape cassettes with different widths, enhancing the device's operational reliability and versatility.
Implementation Method 1
The RFID reader is provided at the second member and is configured to read data stored in the RFID

AI summary
A printing device includes a printing mechanism, a first member, a second member and a RFID. The printing mechanism is configured to perform printing. The first member has a portion constituting a receiving portion. The receiving portion configured to receive therein a holder. The holder retains therein a consumable goods and is provided with a RFID. The holder is contactable with the portion of the first member when the holder is attached to the receiving portion. The second member is movable relative to the first member. The RFID reader is provided at the second member and is configured to read data stored in the RFID.
