Subassembly Logical Binding and Verification Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Theft and robbery of mobile terminal equipment are not effectively hindered as valuable subassemblies can be reused or resold, even if the equipment is encrypted, and counterfeit subassemblies can be installed during maintenance, leading to financial loss for users.
Innovation Solution
A method for logically binding and verifying subassemblies within equipment by setting sub-modules with individual information and a main module that verifies this information, preventing operation if the subassembly is removed or replaced, thus ensuring the subassembly can only function within its original equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption subassembly is used to prevent mobile terminal theft, then equipment security is improved, but subassemblies can still be removed and reused by illegal users
Solution Approach 1:
The patent implements a hierarchical binding structure where subassemblies are bound to the main equipment, and the main equipment is bound to a service platform. This nested binding relationship ensures that subassemblies cannot function independently outside their designated equipment, preventing theft and unauthorized reuse while maintaining equipment security.
Solution Approach 2:
The system establishes real-time verification mechanisms where the main module continuously verifies subassembly identities, and the service platform verifies equipment-subassembly relationships. This feedback loop detects unauthorized removal or replacement attempts and triggers protective actions, effectively preventing subassembly theft and misuse.
2Reliability
If subassembly verification is implemented, then theft prevention is improved, but device complexity increases due to additional verification mechanisms
Solution Approach 1:
The patent introduces a service platform as an intermediary that manages the complex verification logic externally. Instead of embedding complex verification mechanisms within each device, the service platform handles identity authentication, binding relationship management, and verification coordination, thereby reducing device complexity while maintaining robust theft prevention.
Solution Approach 2:
The verification mechanism is designed to be universal and multi-functional, serving multiple purposes including theft prevention, authenticity verification, and maintenance management. By creating a versatile verification system that handles various security scenarios through a unified approach, the patent reduces overall system complexity compared to implementing separate specialized mechanisms for each function.
3Productivity
If original subassembly is replaced during maintenance, then repair efficiency is improved, but counterfeit subassemblies with short operating life cause user loss
Solution Approach 1:
The service platform implements continuous monitoring and verification of subassembly identities during maintenance operations. When a subassembly is replaced, the system automatically verifies its authenticity against the binding database, providing real-time feedback to prevent counterfeit subassemblies from being installed. This ensures that only genuine, high-quality subassemblies replace original components, maintaining reliable operating life while enabling efficient repairs.

AI summary
The present invention discloses a method for logically binding and verifying a subassembly in equipments. The method sets the subassembly in the equipment as a sub-module, and setting a main module in the equipment. the sub-module stores individual information of its own and the main module stores the individual information of the sub-module. The main module sends verification information corresponding to the individual information of the sub-module stored in the main module to the sub-module when the sub-module needs to be verified. The sub-module judges whether the received verification information matches the individual information stored by the sub-module itself after receiving the verification information, if they matches, it is determined that the sub-module is in the legal status, otherwise, it indicates that the sub-module is in the illegal status. The burglarproof technique for the equipment in the present invention can be extended from the level of equipment to the subassemblies, and the present invention has broad applications.
