Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a predetermined identification structure is incorporated into spectacle lenses or frames, then lens identification and device interaction capabilities are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvelens identification capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies optical filters that selectively transmit or block specific wavelengths of light to create identification structures. These filters can be applied as coatings on lenses or integrated into the lens material itself, allowing sensors to detect lens presence and type through optical property variations without adding mechanical complexity

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent replaces potential mechanical identification systems with optical-based identification using filters and sensors. This substitution allows for non-contact, electronic-free detection of lens properties through optical property variations, simplifying the overall system while maintaining identification capabilities

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If invisible identification structures are used in lenses, then user comfort and aesthetics are improved, but detection reliability must be maintained

Engineering Contradiction:
Improveuser comfortVSAvoiddetection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies optical filters with specific spectral characteristics to localized regions of the lens or frame. These filters create distinct optical signatures that sensors can detect while remaining invisible to users. The local application of different filter properties allows reliable differentiation between lens types without affecting overall lens appearance or user comfort

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes variations in optical parameters such as transmission wavelength, reflectivity, or absorption characteristics of the filters to create reliable identification signatures. By changing these optical parameters rather than physical dimensions, the system maintains detection reliability while preserving lens aesthetics and user comfort

Inventive Principle:
Principle #35Parameter changes

AI summary

A system including a sensor configured so that the presence of a spectacle within a detection range of the sensor is detectable by the sensor when the spectacle includes a predetermined identification structure. The system may further include a control unit configured to receive an information from the sensor and to carry out a predetermined action, upon a condition in which the one or more spectacle lenses may be detected. A method may include detecting the presence of the spectacle within a detection range, and further providing, by the sensor, an information to the control unit. The information may confirm the detection of the spectacle. The method may include carrying out, by the control unit, the predetermined action. A computer program product including instructions to cause the system to execute the steps of the method. A computing device including the sensor and a memory.
