Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain and encryption logic are added to ensure data security and integrity, then data security and reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines blockchain logic, encryption/decryption logic, and impact detection functionality into a single integrated device. The housing encloses both the detection assembly and the logic circuits, merging security functions with sensing functions in one unified structure, thereby improving reliability without proportionally increasing overall system complexity.
Solution Approach 2:
The device performs multiple functions: detecting acceleration events, generating cryptographic hashes, encrypting data, and storing information on a blockchain. By making the device universal and multi-functional, the patent achieves high data security and reliability while avoiding the need for separate dedicated security devices, thus managing complexity effectively.
2Measurement precision
If a detection assembly and processing logic are included to detect and secure data, then measurement precision and reliability are improved, but loss of energy increases due to power consumption
Solution Approach 1:
The device performs data encryption and blockchain hashing operations immediately when impact data is generated, rather than processing it later. This preliminary action ensures measurement precision and data integrity while allowing the device to enter low-power states between events, reducing overall energy loss.
Solution Approach 2:
The patent replaces continuous power-intensive electronic monitoring with event-triggered detection. The detection assembly only activates processing logic when an acceleration event occurs, substituting continuous electronic operation with event-driven operation, thereby maintaining measurement precision while significantly reducing energy consumption during normal operation.
