Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fingerprints are collected to enable individual lighting settings, then personalization is improved, but data privacy security deteriorates
Solution Approach 1:
The patent extracts only the essential fingerprint data needed for identification and discards the rest. By using hash functions to process fingerprint data, the system retains only the anonymized hash value for storing and matching, while the original fingerprint data is not stored or transmitted, thus achieving personalization without compromising data privacy security
Solution Approach 2:
The patent introduces hash functions as an intermediary between the fingerprint data and the lighting control system. The hash function transforms the fingerprint into a fixed-length hash value that serves as a key for retrieving lighting settings, while the original fingerprint data remains hidden and inaccessible to the system, thereby enabling personalization while maintaining data privacy security
2Ease of operation
If fingerprints are stored to enable repeatable access, then functionality is improved, but data privacy security deteriorates
Solution Approach 1:
The patent extracts only the hash value from the fingerprint data for storage and uses it for repeatable access. The hash value is a condensed, anonymized representation that can be stored and matched without exposing the original fingerprint, thus enabling repeatable access to lighting settings while maintaining data privacy security
Solution Approach 2:
The patent creates a copy of the fingerprint data in the form of a hash value for storage and matching purposes. This hash copy can be repeatedly used to retrieve lighting settings without exposing the original fingerprint data, thereby enabling repeatable access while preserving data privacy security
3Ease of operation
If biometric sensors are integrated into switches, then ease of operation is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges the biometric sensor functionality with the existing switch component. By integrating the fingerprint sensor into the switch housing or structure, the system combines two functions (switching and fingerprint recognition) into a single unified component, thereby improving ease of operation while minimizing the increase in device complexity
