Solution Overview
Problem
There is a need for a construction kit that allows children to understand and construct electric motor concepts, enabling them to study motor performance without requiring tools or complex assembly processes.
Innovation Solution
A motor assembly kit comprising a base structure, magnet, coil, bearing, and removable components such as magnet brackets, rotor plates, and coil cradles, which can be snapped together to form a rotor and stator, allowing users to construct a basic electromagnetic motor by aligning and inserting components into pre-cut holes, with optional inclusion of a control unit for adjusting rotation speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional motor assembly methods are used, then motor performance can be achieved, but assembly requires tools and complex processes that are difficult for children
Solution Approach 1:
The motor assembly is divided into discrete, pre-fabricated components including magnet brackets, coil cradles, rotor plates, and a base structure. Each component is designed as a separate module with standardized connection interfaces, allowing children to assemble the motor by simply connecting these segments without requiring tools or understanding complex assembly processes.
Solution Approach 2:
Critical sub-assemblies such as the magnet brackets, coil cradles, and rotor plates are pre-fabricated with integrated features (pre-attached magnets, pre-positioned coil supports, pre-drilled alignment holes) before being provided to the user. This preliminary preparation eliminates the need for children to perform complex fabrication or alignment tasks during assembly.
2Adaptability or versatility
If a complete motor assembly is provided, then motor performance can be studied, but children cannot understand individual component functions
Solution Approach 1:
The motor is segmented into functionally distinct components (magnet assembly, coil assembly, rotor, stator) that can be independently manipulated, removed, and reconfigured. This segmentation allows children to study each component's function separately while maintaining the ability to assemble complete motor configurations for performance studies.
Solution Approach 2:
The component support structures are designed to be dynamically reconfigurable, allowing children to adjust component positions, remove components for individual study, or reassemble them in different configurations. This dynamic adaptability enables both educational exploration and functional motor assembly.
3Ease of operation
If removable component supports are used, then components can be easily assembled and disassembled, but structural stability during operation may be compromised
Solution Approach 1:
The connection interfaces between components feature localized high-strength attachment mechanisms (such as snap-fit features, interlocking geometries, or friction-fit interfaces) concentrated at critical joint locations. This ensures that while components remain removable for assembly and disassembly, the assembled motor achieves sufficient structural stability during operation.

AI summary
In some examples, a motor assembly kit includes a magnet, a coil, a bearing, and a flat assembly. The flat assembly includes a base structure, a first plurality of components, and a second plurality of components. The first plurality of components are removable from the flat assembly to construct a magnet support to support the magnet above the base structure. The second plurality of components are removable from the flat assembly to construct a coil cradle to support the coil above the base structure.
