Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing surf disc systems are used, then basic water riding function is provided, but safety, convenience, and entertainment are insufficient
Solution Approach 1:
The patent applies local quality by creating specific functional zones on the surf disc surface: a central raised dome region for stable footing and control, surrounded by a textured grip zone, and an outer rim for edge control. This zoned surface design with varying textures and elevations provides different tactile feedback and functional properties in different areas, enhancing both safety through stable footing and entertainment through varied interaction possibilities.
Solution Approach 2:
The patent utilizes spheroidality by incorporating a hemispherical dome in the center of the disc and curved textured patterns on the surface. The domed central region provides a naturally stable platform that conforms to foot pressure, while the curved surface patterns enhance grip and control. These curved geometries improve safety by providing stable footing and enhance entertainment through dynamic interaction with the water surface.
2Stability of the object's composition
If surf disc system performs well in windy conditions, then stability is improved, but design complexity increases
Solution Approach 1:
The patent applies the counterweight principle by positioning the hemispherical dome centrally on the disc to create a weighted center that resists tipping and rotational instability caused by wind. The dome's elevated mass acts as a counterbalancing element that maintains orientation stability without requiring complex active control systems, thus improving wind resistance while maintaining simple passive design.
Solution Approach 2:
The patent utilizes composite materials by combining multiple material properties in the disc construction: a rigid structural base material for overall shape and stability, combined with elastomeric or textured surface materials for grip and wind resistance. This multi-material approach enhances stability in windy conditions through material properties rather than complex structural additions, maintaining design simplicity.
3Duration of action of stationary object
If surf disc system is durable and cost-effective, then manufacturing quality is improved, but manufacturing complexity may increase
Solution Approach 1:
The patent applies merging by integrating multiple functional features into a single monolithic disc structure: the dome, surface textures, rim features, and structural elements are all formed as one unified component rather than separate parts requiring assembly. This consolidation improves durability by eliminating joints and weak points while simplifying manufacturing to a single molding or fabrication process, thereby enhancing ease of manufacture.
Solution Approach 2:
The patent utilizes parameter changes by varying the disc's geometric parameters during manufacturing - specifically creating zones of different heights (dome vs. surface vs. rim), textures (smooth vs. textured), and densities through selective material deposition or molding techniques. These parameter variations are achieved through standard manufacturing processes like injection molding with multi-level cavities, maintaining ease of manufacture while achieving enhanced durability through optimized structural parameters.
