Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If personal data is de-identified for marketing use, then privacy protection is improved, but target marketing effectiveness deteriorates
Solution Approach 1:
The patent introduces a personal data intermediary service that acts as a mediator between data subjects and companies. The intermediary securely stores personal data, manages access permissions, and enables controlled sharing without requiring full de-identification. This resolves the contradiction by allowing identified personal data to be used for effective target marketing while maintaining privacy through permission-based access control and security measures.
2Productivity
If personal data is collected for marketing purposes, then marketing effectiveness is improved, but user control and transparency deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where data subjects receive notifications when their personal data is accessed by companies, along with information about the purpose and scope of access. Users can review access logs and modify their permission settings at any time. This feedback loop maintains user control and transparency while enabling effective marketing use of personal data.
Solution Approach 2:
The system dynamically adjusts data access permissions based on user preferences and contextual factors. Users can set different permission levels for different companies or purposes, and these permissions can be modified in real-time. This dynamic permission management enables both effective marketing utilization and ongoing user control.
3Object-affected harmful factors
If personal data is stored securely with user permission, then privacy protection is improved, but data accessibility for marketing deteriorates
Solution Approach 1:
The patent segments personal data into different categories and allows selective sharing of specific data types with different companies based on user permissions. Rather than requiring full data access or complete de-identification, the system enables fine-grained control where users can permit certain data elements to be accessed for specific marketing purposes while maintaining security and privacy protection for other data.
