Transponder Bundle Identification via Pre-Recorded Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bundling objects with transponders for easier transportation and handling often results in incomplete or failed identifier readings due to reduced exposure time in the reading field, antenna interference, and shielding by bundling materials or containers, leading to inefficiencies and missed data transmission.
Innovation Solution
Individual identifiers are recorded and stored in a database before bundling, with a bundle identifier generated for later recognition, allowing for complete data retrieval by reading a single transponder or bundle identifier, and using a separate transponder for reliable reading even in shielded conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If objects are bundled together for transportation and handling, then transportation efficiency and handling ease are improved, but the completeness of transponder identifier reading deteriorates due to reduced exposure time, antenna interference, and shielding effects
Solution Approach 1:
The patent applies preliminary action by recording and storing the identifiers of all transponders in a bundle individually in a database before the bundling occurs. This pre-recording ensures that even if some transponders cannot be read later due to shielding or interference, their identifiers are already available in the database, thus preventing information loss while maintaining transportation efficiency.
2Loss of information
If all transponder identifiers are read individually in real-time during bundle processing, then complete data retrieval is achieved, but processing time and energy consumption increase significantly
Solution Approach 1:
The patent performs the time-consuming task of reading all transponder identifiers individually before bundling, storing them in advance in a database. During subsequent bundle processing, the system only needs to retrieve previously stored identifiers or read a single bundle identifier, dramatically reducing processing time while maintaining complete data retrieval.
Solution Approach 2:
The patent creates a copy of all transponder identifiers and stores them in the database before bundling. This copy allows the system to retrieve bundle information without repeatedly reading all individual transponders during processing, thus saving time while preserving data completeness.
3Loss of time
If a single bundle identifier is used for recognition, then reading time and data traffic are reduced, but reliability deteriorates when the bundle identifier cannot be read due to shielding or interference
Solution Approach 1:
The patent pre-records all individual transponder identifiers in the database before bundling. This creates a backup mechanism where, if the bundle identifier cannot be read due to shielding or interference, the system can fall back on retrieving identifiers from the pre-recorded database entries, thus maintaining reliability while keeping reading time short.
Solution Approach 2:
The patent changes the identification approach from relying solely on a single bundle identifier to using multiple parameters: the bundle identifier for normal fast reading, and the pre-recorded individual transponder identifiers as backup. This multi-parameter approach maintains both speed and reliability by adapting to reading conditions.

AI summary
A method for the complete identification of a plurality of transponder-equipped objects (74, 76) is described, which are bundled and fed to a bundle reader (18, 20, 50, 54). Prior to this, individual identifiers of the transponders with which the objects in the bundle are equipped are read individually or in groups using a capture reader (42, 46, 58), and the individual identifiers and their bundle affiliation are stored in a database (62).When reading the bundle, after reading at least one arbitrary individual identifier and comparing it with the individual identifiers stored in the database (62), all items (74, 76) of the bundle equipped with transponders are considered recognized, or a bundle identifier is generated and stored in a separate bundle transponder arranged on the bundle or in a transponder of the bundle itself temporarily recoded as a bundle transponder, and when reading the bundle and comparing it with the bundle identifier stored in the database (62), all items of the bundle equipped with transponders are considered recognized.
