Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motorized wheel is integrated into a conventional wheelbarrow, then manual effort required for operation is reduced, but device complexity increases
Solution Approach 1:
The conversion kit is divided into separate modular components: motorized wheel assembly, battery/controller plate, and mounting brackets. This segmentation allows the complex motorized system to be installed as discrete units rather than a single integrated system, making the complexity manageable and the installation straightforward.
Solution Approach 2:
The motorized wheel assembly is designed to be compatible with conventional wheelbarrow structures, and the battery system uses standard cordless tool batteries that can be found in most toolboxes. This universality allows the complex motorized system to interface with simple, widely-available components.
2Adaptability or versatility
If cordless tool batteries are used as power source, then accessibility and convenience are enhanced, but weight of the system increases
Solution Approach 1:
The system uses standard cordless tool batteries (such as 18V or 20V lithium-ion batteries commonly used in power tools) as the power source. These batteries are widely available to most consumers who already own power tools, eliminating the need to purchase specialized battery systems and enhancing accessibility and convenience.
3Reliability
If cable raceways and clamps are added to manage electrical connections, then reliability of electrical connections is improved, but device complexity increases
Solution Approach 1:
Cable raceways and cable clamps serve as intermediary components that organize and protect the electrical connections between the motorized wheel, battery, and controller. These simple structural elements provide dedicated pathways for cables, ensuring reliable electrical connections without requiring complex wiring harnesses or connection systems.
