Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional plastic injection molding techniques are used, then manufacturing is cost-effective for simple designs, but complex nested geometric shapes and freely rotating components cannot be produced cost-effectively
Solution Approach 1:
The fidget device is divided into multiple separable components including a center hub, center puck, and nested geometric shapes that can be manufactured independently and assembled together. This segmentation allows each component to be produced using appropriate manufacturing methods, with the center hub and puck using 3D printing for complex geometries and standard molding for simpler parts.
Solution Approach 2:
The device incorporates multiple concentrically nested geometric shapes where smaller shapes are placed within larger ones, creating a compact multi-layer structure. This nesting approach enables complex 3D geometries to be manufactured efficiently using 3D printing technology while maintaining cost-effectiveness through reduced material usage and integrated design.
2Adaptability or versatility
If a freely rotating center puck is added for dynamic interaction, then device versatility and sensory stimulation are improved, but device complexity increases
Solution Approach 1:
The center hub serves multiple functions simultaneously: it acts as a rotational pivot for the center puck, provides structural support for the nested geometric shapes, and serves as an assembly reference point. This multi-functionality reduces the need for separate components, thereby managing complexity while maintaining dynamic interactive capabilities.
Solution Approach 2:
The center puck is designed to be freely rotatable about three orthogonal axes, enabling dynamic interaction and unlimited rotational freedom. This dynamic feature provides versatile sensory stimulation through varied rotation patterns while the removable nature of the puck allows for customization without permanently increasing structural complexity.
3Ease of operation
If multiple concentric nested geometric shapes are implemented, then visual and tactile sensory stimulation is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The nested geometric shapes utilize standardized dimensional parameters and modular design elements that can be systematically varied to create different configurations. By using consistent spacing, standardized radii, and modular geometric units, the design achieves precise visual and tactile patterns while simplifying manufacturing through repeated use of standard dimensions and 3D printing capabilities.

AI summary
A handheld fidget device that has a spinnable, rotational and removable center puck. The center puck can freely rotate about the x, y and z axis, similar to a gimbal. The fidget device can contain interlocking and nested concentric geometric rings and each ring is held in place by the smaller ring nested inside it. This allows each ring to move within the inner and outer ring, allowing the fidget device to have 2D and 3D geometric shapes that make satisfying designs as well as satisfying sounds. The interchangeable center puck can be personalized or branded to contain logos and multicolor art. This fidget device has sensory stimulation that is visual, auditory and tactile and implementing scented materials can touch the sense of smell, allowing this fidget device to stimulate 4 of the 5 human senses.
