Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple types of attachments are prepared to accommodate different temple cross-sectional shapes, then the adaptability to various temple types is improved, but the device complexity and user burden increase due to the need to select and manage multiple attachments

Engineering Contradiction:

Improveadaptability to different temple shapesVSAvoidnumber of attachments required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single attachment structure with a composite cross-sectional shape that can accommodate multiple temple types. The attachment features a slit with a cross-section combining a circular portion and a rectangular portion, allowing it to universally fit both circular and rectangular temples without requiring multiple specialized attachments.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges multiple shape characteristics into one attachment design. The slit's cross-sectional shape combines a circular portion and a rectangular portion, effectively merging the accommodation capabilities of what would otherwise require separate circular and rectangular attachments into a single unified structure.

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If multiple types of attachments are prepared for different temple shapes, then the fit accuracy for specific temple types is improved, but the loss of substance increases due to packaging and storage of unused attachments

Engineering Contradiction:

Improvefit accuracy to temple shapeVSAvoidwaste from unused attachments

Core Design Contradiction:

Manufacturing precisionVSLoss of substance

Solution Approach 1:

By creating a universal attachment that works with multiple temple types, the invention eliminates the need to manufacture, package, and store multiple specialized attachments that would otherwise go unused, thereby reducing material waste.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention recovers the value of attachment designs by consolidating multiple specialized attachments into one multi-functional attachment, preventing the waste that would occur from discarding or storing unused specialized attachments.

Inventive Principle:

Principle #34Discarding and recovering

3Device complexity

If a single attachment is used for multiple temple shapes, then the device complexity is reduced, but the fit accuracy may deteriorate due to the compromise in shape matching

Engineering Contradiction:

Improvenumber of attachmentsVSAvoidfit accuracy to temple shape

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The invention merges circular and rectangular shape characteristics into a composite cross-sectional shape for the slit. This combined shape features both a circular portion and a rectangular portion, allowing it to maintain high fit accuracy for both circular and rectangular temples while using a single attachment.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The slit's cross-sectional shape incorporates different geometric characteristics in different regions - a circular portion for accommodating circular temples and a rectangular portion for accommodating rectangular temples. This local differentiation within the unified attachment structure enables precise fitting for various temple types.

Inventive Principle:

Principle #3Local quality

AI summary

There is provided a temple clip as an attachment capable of mounting an external device or the like to temples having a plurality of types of cross-sectional shapes. The temple clip includes a block body having a slit through which a temple of eyewear is inserted to hold the temple, wherein a cross-sectional shape of the slit includes a shape obtained by combining shapes matching cross-sectional shapes of at least two types of temples. The temple clip may include a U-shaped leaf spring that is placed over the block body and biases in a direction of reducing a width of the slit.
