Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the front beam is made deformable to allow user adjustment of convergence angle, then the spectacles become adjustable for convergence, but the adjustment becomes inconvenient and imprecise

Engineering Contradiction:

Improveadjustability of convergence angleVSAvoidconvenience and precision of adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The front beam is made deformable through a core made of elastic memory material that can be deformed by body heat from the user's nose, enabling dynamic adjustment of the convergence angle. This allows the spectacles to adapt to different user needs while maintaining ease of adjustment through simple placement rather than complex mechanical operations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The elastic memory material in the front beam automatically deforms in response to body heat from the user's nose, providing self-adjusting convergence without requiring manual manipulation. The material's thermal response to the user's body heat enables automatic adaptation to the desired convergence angle.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If manual deformation of the front beam is used for adjustment, then convergence angle can be changed, but the precision of imposing the desired angle is insufficient

Engineering Contradiction:

Improveconvergence angle adjustment capabilityVSAvoidprecision of convergence angle

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system provides visual feedback through the magnifying eyepieces, allowing the user to observe the magnified image and automatically adjust the convergence angle to achieve correct binocular vision. The visual system's natural feedback mechanism enables precise convergence adjustment without requiring external measurement tools.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If traditional frame structures are used with magnifying eyepieces, then the spectacles can provide magnification, but the convergence adjustment becomes complicated

Engineering Contradiction:

Improvemagnification with eyepiecesVSAvoidcomplexity of convergence adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment mechanism is merged with the frame structure itself through the elastic memory material integrated into the front beam. This eliminates the need for separate adjustment mechanisms while maintaining both magnification capability and convergence adjustability, simplifying the overall device.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A frame for spectacles with magnifying lenses includes a magnifying eyepiece for mounting on each lens. The frame includes:a front mount including, for each lens, a respective slot extending between a central region of the nose support mount and an opposite lateral region of the mount, each slot being configured to receive a portion of a respective lens-carrying support, partially surrounding a peripheral edge portion of the lens, andfixing means for fixing the lens-carrying support which is received in the respective slot to the front mount.The lens-carrying support is received in the corresponding slot with a coupling play transverse to the front mount, and the fixing means are configured to fix each lens-carrying support to the front mount in a preselected relative positioning which is allowed by the coupling play, making the orientation of each lens adjustable with respect to the front mount.
