Construction Machine Smart Key Registration for Multi-Machine Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconvenience of carrying multiple smart keys for managing and operating multiple construction machines increases the likelihood of losing a key, and existing solutions do not effectively address this issue.
Innovation Solution
A method for registering a smart key in a construction machine using a first password generated in a smart key module, which is then authenticated through a user terminal, allowing the registration of a near smart key's authentication code as a new registration authentication code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user carries multiple smart keys to manage multiple construction machines, then the user can operate different machines, but the likelihood of losing a key increases and convenience decreases
Solution Approach 1:
The patent implements a universal smart key system where a single smart key can be registered to control multiple construction machines. The smart key module stores authentication codes for different machines, allowing one smart key to perform the function of multiple keys, thereby eliminating the need to carry multiple separate keys while maintaining the ability to operate different machines
Solution Approach 2:
The patent merges multiple authentication functions into a single smart key by registering multiple construction machine authentication codes within one smart key module. This combining approach allows the user to manage multiple machines with one key, reducing the risk of loss and improving convenience
2Ease of operation
If a smart key registration system is implemented without server communication, then registration can be performed offline, but security may be compromised
Solution Approach 1:
The patent implements a self-service registration mechanism where the smart key module and user terminal can complete authentication and registration independently without requiring external server communication. The system generates authentication codes locally and performs verification autonomously, enabling offline registration while maintaining operational security through cryptographic methods
Solution Approach 2:
The patent prepares security measures in advance by implementing cryptographic variable generation and authentication code creation before any potential communication issues arise. The system has pre-configured security protocols and local authentication capabilities that function independently, ensuring security is maintained even when server communication is unavailable

AI summary
In a method of registering a smart key for construction machinery, a first password is generated in a smart key module mounted in a construction machine. A user setting graphic interface through which a user can input a password, in the smart key module or a user terminal, is provided to the user. The password inputted by the user is compared with the first password in the smart key module to authenticate. An authentication code of a near smart key that is recognized by the smart key module is registered as a new registration authentication code when the inputted password is authenticated.
