Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing figure skates use complex structures to achieve stability and functionality, then the skating performance is improved, but the production complexity increases and the aesthetic elegance deteriorates

Engineering Contradiction:
Improveskating performanceVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The figure skate is divided into distinct modular components: shell case, toe cap, ice skate blade, and sole assembly. Each component is independently manufactured and then assembled through riveting, allowing for simplified production of individual parts while maintaining overall structural integrity and skating performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sole assembly is nested within the shell case and toe cap structure, with the ice skate blade attached to the bottom surface. This nested arrangement consolidates multiple functional elements into a compact integrated unit, reducing overall structural complexity while preserving all necessary skating functions.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If existing figure skates use multiple components to achieve functionality, then the skating capability is improved, but the production process becomes more difficult and time-consuming

Engineering Contradiction:
Improveskating capabilityVSAvoidproduction ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The figure skate is divided into distinct modular components: shell case, toe cap, ice skate blade, and sole assembly. Each component is independently manufactured and then assembled through riveting, allowing for simplified production of individual parts while maintaining overall structural integrity and skating performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sole assembly is pre-formed with the ice skate blade already attached to its bottom surface before being integrated into the main skate structure. This preliminary assembly of sub-components streamlines the overall manufacturing process by reducing the number of separate assembly operations required.

Inventive Principle:
Principle #10Preliminary action

3Shape

If existing figure skates use elaborate designs to achieve elegance, then the aesthetic appearance is improved, but the structural simplicity deteriorates and production becomes more complex

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidstructural simplicity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The shell case and toe cap feature a refined 'W'-shaped butting line that creates an elegant visual pattern on the outer surface. This localized aesthetic feature is achieved through precise rivet placement and edge alignment, enhancing the visual appeal without requiring complex internal structures or additional decorative components.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The front sole incorporates an arc-shaped upper groove surface that seamlessly connects with the inner sole's arc-shaped lower groove surface. These curved geometric features contribute to the elegant aesthetic appearance while maintaining structural simplicity through continuous smooth transitions rather than angular or segmented designs.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

Disclosed is a figure skate, which includes a shell case, a toe cap, and an ice skate blade. The shell case and the toe cap are fixedly connected through rivets on both sides. An inner side of a front end at the bottom of the shell case has open butted front sole and front inner groove, an outer side of a back end of the toe cap has open butted inner sole and back outer groove, and rivet connecting holes are formed in the front inner groove and the back outer groove. The back outer groove and the front inner groove are in seamless connection. The front sole has an arc-shaped upper groove surface, and the inner sole has an arc-shaped lower groove surface. The inner sole and the front sole, as well as the lower groove surface and the upper groove surface all are in seamless connection.
