Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cart has fixed wheels, then the cart can carry goods stably, but the cart occupies excessive space and cannot be stored efficiently
Solution Approach 1:
The wheel connecting structure employs a dynamic design where wheels can transition between extended and retracted positions. The rotating assembly allows the wheel connecting structure to rotate relative to the body structure, enabling the wheels to be positioned according to operational needs rather than being fixed in place.
Solution Approach 2:
The wheel connecting structure is designed to be nested within or alongside the body structure when retracted. The rotating assembly and linking assembly allow the wheel connecting structure to be compacted into a space-efficient configuration that minimizes overall cart volume during storage.
2Adaptability or versatility
If the cart has fixed wheels, then the cart structure is simple, but the cart lacks functionality for easy storage and deployment
Solution Approach 1:
The wheel connecting structure serves multiple functions: it provides stable ground contact when extended, enables compact storage when retracted, and can be positioned flexibly through rotation. This multi-functional design allows a single structure to handle both operational and storage requirements without needing separate mechanisms.
Solution Approach 2:
The wheel assembly is segmented into distinct functional components: the body structure, wheel member, rotating assembly, and linking assembly. This segmentation allows each component to perform its specific function independently while contributing to the overall adaptability of the cart system.
3Productivity
If the cart uses manual wheel deployment, then the structure can be simple, but the deployment process is time-consuming and labor-intensive
Solution Approach 1:
The driving assembly incorporates an energy assembly that automatically provides the force needed for deployment and retraction. When the linking assembly moves between positions, the energy assembly autonomously drives the rotating assembly to rotate, extending or retracting the wheels without requiring manual intervention.
Solution Approach 2:
The manual mechanical effort previously required for wheel deployment is replaced by an energy assembly that converts stored energy into mechanical motion. This substitution eliminates the need for users to manually manipulate the wheel connecting structure, significantly reducing deployment time and labor.
