Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for determining identity or authorization and enabling physical access to devices often require direct wireless connectivity between identification media and access units, which limits compatibility with identification media that use different data transmission technologies or have short-range interfaces, making it difficult to use various identification media for personalized identification or authorization.
Innovation Solution
A system where a separate, stationary unit wirelessly connects to a portable identification medium, enabling identity verification or authorization through wireless data communication between the first unit, the second unit, and the identification medium, using different air interfaces and authentication methods to facilitate compatibility with various identification media, including those with short-range interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct wireless connectivity is required between identification media and access units, then system security is improved, but compatibility with various identification media is worsened
Solution Approach 1:
The patent introduces a second unit as an intermediary device that mediates between the identification medium and the first unit (access control system). This second unit receives data from the identification medium via a first air interface, processes it locally, and then communicates with the first unit via a second air interface. This intermediary approach allows the system to maintain security requirements while enabling compatibility with various identification media that may have different communication protocols or ranges.
2Device complexity
If identification media with short-range interfaces are used, then device simplicity is improved, but communication range is worsened
Solution Approach 1:
The patent extends the communication capability from a single direct link to a multi-hop communication path. The identification medium communicates with the second unit over a first air interface (potentially short-range), and the second unit relays this information to the first unit over a second air interface. This dimensional extension of the communication path allows short-range devices to effectively achieve longer communication ranges through relay.
3Adaptability or versatility
If a separate second unit is introduced for wireless communication, then adaptability to different identification media is improved, but device complexity is worsened
Solution Approach 1:
The patent divides the access control system into separate functional units: a first unit (access control device), a second unit (communication intermediary), and the identification medium. This segmentation allows each unit to be optimized for its specific function and enables different identification media to be used without modifying the core access control logic in the first unit. The second unit handles the variability and complexity of different communication protocols.
4Adaptability or versatility
If abstract identity verification is implemented, then system flexibility is improved, but measurement precision of authorization is worsened
Solution Approach 1:
The patent implements preliminary action by having the second unit perform initial data reception and processing from the identification medium before the final authorization decision is made by the first unit. The second unit can pre-validate the data format, check basic credentials, or prepare the information in a standardized form, thereby maintaining precision while enabling flexible abstract verification at the access control level.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the use of diverse identification media for personalized identification and authorization, reducing the need for direct wireless connectivity and allowing for secure, abstract identity or authorization verification, even with media that cannot communicate directly with the access unit.
Implementation Method 1
