Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user carries multiple smart keys to operate multiple construction machines, then the ability to control multiple machines is improved, but the convenience of operation deteriorates due to the high probability of losing smart keys and the burden of carrying them all
Solution Approach 1:
The patent merges multiple authentication codes into a single smart key device. The smart key stores multiple authentication codes corresponding to different construction machines and can selectively activate them. This combining approach allows the user to carry one smart key instead of multiple separate keys, resolving the contradiction between controlling multiple machines and maintaining convenience.
Solution Approach 2:
The smart key is designed with multi-functionality to perform authentication for multiple different construction machines. It contains a database of authentication codes and can switch between them based on which machine needs to be operated. This universal design eliminates the need for machine-specific keys while maintaining secure access control.
2Ease of operation
If multiple authentication codes are stored in one smart key, then the convenience of carrying one key is improved, but the security risk increases due to potential loss or unauthorized access
Solution Approach 1:
The patent segments the authentication codes within the smart key so that they are stored separately and can be individually activated. When the smart key communicates with a construction machine, only the specific authentication code corresponding to that machine is transmitted and validated. This segmentation ensures that even if one code is compromised, others remain secure.
Solution Approach 2:
The smart key employs dynamic activation of authentication codes based on the target construction machine. The system determines which code to use based on machine identification, and only that specific code is made active for transmission. This dynamic approach prevents unauthorized use of other stored codes while maintaining the convenience of having multiple codes in one device.
