Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If complex multi-component molds and manual processing steps are used to create structural features and decorative designs, then manufacturing precision and aesthetic quality are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveprecision of structural features and decorative designsVSAvoidcomplexity of manufacturing processes
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical molding processes with laser technology. The laser system directly writes structural features and decorative designs onto the footwear surface through optical energy, eliminating the need for complex multi-component molds and manual processing steps while maintaining high precision.

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

Solution Approach 2:

The patent introduces a masking layer as an intermediary between the laser and the footwear surface. This masking layer selectively protects certain areas from laser treatment, enabling precise control over where structural features and decorative designs are created without requiring complex mechanical masking or positioning systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If complex multi-component molds and manual processing steps are used to create structural features and decorative designs, then manufacturing precision and aesthetic quality are improved, but manufacturing time and labor costs increase

Engineering Contradiction:
Improveprecision of structural features and decorative designsVSAvoidmanufacturing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The laser-based system performs both structural feature creation and decorative design application in a single automated process, eliminating multiple sequential manual steps including molding, assembly, and post-processing. This integration dramatically reduces total manufacturing time while maintaining precision through computer-controlled laser positioning.

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

Solution Approach 2:

The masking layer is applied in advance to protect areas that should not be treated by the laser. This preliminary action allows the laser process to directly create the final structural features and decorative designs without requiring subsequent manual refinement or post-processing steps.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If traditional manufacturing processes are used to create structural features, then structural integrity is maintained, but adaptability for customization is reduced

Engineering Contradiction:
Improvestructural integrity of footwearVSAvoidcustomization capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The laser system provides dynamic adaptability by allowing different structural features and decorative designs to be created on the same footwear component without changing physical tools or molds. The laser parameters and patterns can be dynamically adjusted through software to customize footwear for different athletic needs while maintaining structural integrity through controlled material modification.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes parameter changes in the laser process (wavelength, power, pulse duration, scanning speed) to create various structural features and decorative designs on the footwear surface. By changing laser parameters rather than physical tooling, the system achieves both structural integrity and customization adaptability.

Inventive Principle:
Principle #35Parameter changes

AI summary

The invention relates to footwear and portions thereof having structural features and decorative designs thereon, and related systems and methods for manufacturing same. An exemplary method for providing a feature on a surface of an object includes positioning a laser (20) proximate the surface of the object, directing a laser beam (25) from the laser (20) to the surface of the object to mark or engrave at least a portion of the surface of the object, and moving at least one of the laser (20) and the object to create a pattern on the surface of the object, the pattern providing at least one of an aesthetic and a structural feature on the surface of the object.
