Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate active and passive RFID modules are used for different phases, then identification and supervision capabilities are achieved, but attachment and detachment operations become complex and time-consuming
Solution Approach 1:
The patent combines the active RFID module and passive RFID module into a single integrated module, eliminating the need for separate attachment and detachment operations. The integrated module contains both the active component (with battery, transmitter, and sensors) and the passive component (with antenna and memory), allowing it to perform both identification and supervision functions in one unit.
Solution Approach 2:
The integrated RFID module is designed to perform multiple functions: it can operate in passive mode for identification during storage phases, and switch to active mode for supervision and monitoring during transport phases. This multi-functionality eliminates the need to attach different modules for different phases, reducing operational complexity and time.
2Adaptability or versatility
If separate active and passive RFID modules are attached to objects, then both identification and supervision needs are met, but the number of manual operations and error risks increase
Solution Approach 1:
By merging the active and passive RFID modules into a single integrated unit, the patent reduces the number of manual attachment operations from two (one for each module) to one. This reduction directly lowers the risk of errors such as attaching the wrong module or failing to properly associate modules with objects in the database.
Solution Approach 2:
The integrated module automatically manages its own operation mode based on its state. When attached to an object, it can autonomously switch between passive identification mode and active supervision mode, eliminating the need for manual configuration or programming for each phase, thereby reducing operational errors.
3Ease of operation
If active RFID modules are used for supervision phases, then data collection and long-range communication are enabled, but battery management becomes prohibitively complex and costly
Solution Approach 1:
The patent merges the battery-powered active RFID module with the passive RFID module into a single integrated unit. The passive module serves as a permanent identifier attached to the object, while the active module with battery is temporarily attached only when supervision is needed. This integration allows the system to share the passive module's identification data, reducing the need for separate battery management systems for each active module.
Solution Approach 2:
The system dynamically switches between passive and active modes based on operational needs. During storage phases, only the passive module is active, avoiding battery consumption. During transport phases, the active module is temporarily powered to perform supervision tasks, then powered down. This dynamic operation reduces overall battery management complexity and extends battery life.
4Loss of energy
If passive RFID modules are used for storage phases, then battery management is avoided, but supervision and sensor data recording are not possible
Solution Approach 1:
The integrated RFID module dynamically adapts its operational mode based on the phase of use. During storage phases, it operates in passive mode, consuming no battery power and relying on the infrastructure to initiate communication. During transport or supervision phases, it automatically switches to active mode, utilizing the battery to enable sensor data collection, long-range communication, and initiated transmissions.
Solution Approach 2:
The integrated module is designed to perform both passive identification and active supervision functions within a single device. It incorporates both the passive RFID components (antenna, memory) and active RFID components (battery, transmitter, sensors), allowing it to seamlessly transition between identification-only mode and supervision mode with sensor data recording, eliminating the need for separate modules.

AI summary
Modular radio-identification system (1) of the type comprising: -a first passive radio-identification module (2) comprising a housing (20) inside which is disposed a memory (21) for storing an identification datum linked to an antenna (22); and -a second active radio-identification module (3) comprising a housing (30) inside which is disposed a controller (31) linked to a supply battery (32), to a transmiter/receiver (33) and to at least one sensor (34); in which the housings of the two modules are equipped with means of reversible and complementary fixing (24, 36) which are adapted for co-operating together so as to allow the reversible fixing of the second module on the first module; and the modules comprise means of electrical connection (23, 35) which are adapted for establishing an electrical connection between the memory of the first module and the controller of the second module once the second module is fixed on the first module. The system may possibly be supplemented with a hood for covering the first module. The present invention finds an application in the fields of identification, location, supervision and monitoring of objects or persons.
