Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing need for multiple applications on chip cards requires larger memory and hardware, increasing production costs due to the one-to-one correspondence between entries and implementations, making efficient use of resources challenging.
Innovation Solution
Implementing multiple entries that refer to the same application on a chip card, allowing for the same application to be used multiple times, simulating separate applications with different virtual applications, thus optimizing memory and hardware usage.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple applications are implemented on the same chip card with one-to-one correspondence between entries and implementations, then the functionality and versatility of the chip card are improved, but the memory size and hardware resources required increase
Solution Approach 1:
The patent implements multi-functionality by allowing a single application implementation to be referenced by multiple entries in the chip card memory. Each entry can have different parameters (such as different security contexts, application profiles, or configuration data) while pointing to the same underlying implementation, enabling the same code to serve multiple functional purposes without requiring separate implementations for each application.
Solution Approach 2:
The patent merges multiple application implementations into a single shared implementation that can be accessed through multiple entries. By combining the common functional code into one implementation and allowing different entries to reference it with their own specific parameters, the patent reduces the total memory required while maintaining the ability to support multiple applications with different functionalities.
2Adaptability or versatility
If multiple applications are implemented on the same chip card with one-to-one correspondence between entries and implementations, then the versatility of the chip card is improved, but the production costs increase
Solution Approach 1:
The patent reduces production costs by implementing universality, where a single application implementation can serve multiple purposes through different entries. This approach reduces the total number of implementations needed, thereby reducing memory requirements and hardware resources, which directly translates to lower production costs while maintaining versatile functionality.
Solution Approach 2:
By merging multiple application implementations into a single shared implementation accessible through multiple entries, the patent reduces the overall complexity and resource requirements of the chip card. This consolidation reduces manufacturing complexity and material requirements, leading to lower production costs.
3Adaptability or versatility
If multiple applications are implemented on the same chip card with one-to-one correspondence between entries and implementations, then the functionality is improved, but the hardware resources required increase
Solution Approach 1:
The patent applies universality by designing a hardware architecture where a single application implementation can be invoked through multiple entries, each with different parameters. This reduces the need for multiple separate implementation copies in hardware, thereby reducing device complexity while maintaining the ability to support multiple applications with different functionalities.
Solution Approach 2:
The patent merges multiple application implementations into a single shared implementation that can be accessed through different entries. This consolidation reduces the hardware resources required, as the same code and data structures are shared across multiple applications rather than being duplicated, thereby reducing device complexity.
