Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for secure storage of sensitive objects like keys and weapons require multiple reader modules for each object, leading to high production costs due to the unit cost of each reader module.
Innovation Solution
A method and device that utilize electromagnetic coupling between wireless transmission means of objects and a common secondary fixed antenna, which is connected to a primary fixed antenna connected to a reader module, allowing a single reader module to communicate with multiple objects and reducing production costs by sharing electrical energy and identification data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple reader modules are provided for each object with identification means, then reliable detection and identification of each object is achieved, but production costs increase significantly
Solution Approach 1:
A single reader module is designed to serve multiple receiver modules through the shared secondary antenna system. The reader module performs universal detection and identification functions for all objects in the system, eliminating the need for dedicated reader modules at each receiver module while maintaining reliable object detection and identification.
Solution Approach 2:
Multiple receiver modules are merged into a single detection system by connecting their fixed antennas to a common secondary antenna. This consolidation allows one reader module to detect and identify multiple objects simultaneously or sequentially, significantly reducing the total number of reader modules needed and lowering production costs.
2Ease of manufacture
If a single reader module is shared among multiple receiver modules, then production costs are reduced, but detection and identification capability must be maintained
Solution Approach 1:
A secondary fixed antenna serves as an intermediary between multiple receiver module antennas and the single reader module. This intermediary component enables the reader module to communicate with multiple receiver modules without requiring direct connection to each one, maintaining detection and identification capability while reducing system complexity and cost.
Solution Approach 2:
The antenna system is segmented into fixed antennas at each receiver module, a secondary antenna that collects signals from multiple fixed antennas, and a primary antenna at the reader module. This segmentation allows distributed detection points while centralized signal processing, maintaining reliable object detection across multiple locations with a single reader module.

AI summary
A method of detecting and identifying an object (O) which is provided with identification elements (Io) and wireless transmission elements (Ao), the object being disposed close to one receiver module (Mi) from among a plurality of receiver modules (M1, . . . , Mi, . . . , Mn). The inventive method includes: (i) an electromagnetic coupling between the object's wireless transmission elements (Ao) and a fixed antenna (Ai) which is associated with the aforementioned receiver module (Mi); and (ii) an electrical coupling between the fixed antenna (Ai) of the receiver module (Mi) and a secondary fixed antenna (3) which is common to all of the fixed antennas (A1, Ai, . . . , An) of the receiver module. Moreover, the common secondary fixed antenna (3) is electromagnetically coupled to a primary fixed antenna (2) which is connected to a read module (4) that is designed to read the identification data originating from the identification elements (Io).
