Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional written documentation methods are used for production steps, then documentation can be completed, but administrative effort and documentation time are excessively high
Solution Approach 1:
The patent replaces manual written documentation with an automated digital system. The data glasses capture images automatically, and the cryptographic signature system automates the authentication and signing process, eliminating the need for manual writing and physical signatures. This substitution of mechanical manual processes with automated digital systems directly resolves the contradiction by dramatically reducing both administrative effort and documentation time while maintaining audit-proof documentation.
2Loss of information
If traditional written documentation is used, then documentation can be completed, but images of production steps cannot be included
Solution Approach 1:
The patent merges multiple functions into the data glasses device: image capture, user authentication, and cryptographic signing. By combining these functions into a single wearable device, the system enables comprehensive documentation with visual information without proportionally increasing overall system complexity. The integration of camera, authentication device, and communication interface in one unit allows images to be captured and signed efficiently.
Solution Approach 2:
The patent introduces a signature creation unit as an intermediary component that handles the cryptographic signing process. This intermediary receives image data from the data glasses, performs the cryptographic signing operation, and returns the signed data. This mediator approach allows the system to include complex cryptographic functionality without requiring the data glasses themselves to handle all processing, thus managing complexity while enabling comprehensive documentation with images.
3Reliability
If cryptographic signing is implemented for image data, then audit-proof documentation is achieved, but system complexity increases
Solution Approach 1:
The patent segments the cryptographic signing system into distinct functional components: the data glasses handle image capture and initial authentication, while a separate signature creation unit performs the cryptographic signing operation. This segmentation allows the complex cryptographic functionality to be isolated in a dedicated component, making the overall system more manageable and maintainable while still achieving audit-proof documentation through cryptographic signatures.

AI summary
The invention relates to data glasses (100) for cryptographically signing image data using a signature creation unit, wherein the data glasses (100) can be worn by a user. The data glasses (100) comprise an image camera (101), which is designed to capture an image in order to obtain the image data, the image data representing the captured image. The data glasses (100) also comprise an authentication device (103), which is designed to authenticate the user. The data glasses (100) additionally comprise a communication interface (105), which is designed, in response to the authentication of the user, to transmit the image data to the signature creation unit in order to sign the image data cryptographically.
