Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual towing is used for folding wagons, then the structure remains simple and easy to manufacture, but it becomes labor-intensive and inconvenient especially when carrying loads uphill
Solution Approach 1:
The patent replaces the purely mechanical manual towing system with an electric power assistance system. Electric wheels with motors are integrated into the folding wagon structure, allowing electronic control to supplement or replace manual pushing forces. This substitution directly addresses the labor-intensive nature of manual towing while maintaining the foldable structure for portability.
Solution Approach 2:
The folding wagon is designed with multi-functionality to serve both as a simple cargo cart and as a powered vehicle. The electric wheels can operate in multiple modes: pure electric propulsion, hybrid power-assist mode, and manual towing mode. This universality allows the same device to adapt to different usage scenarios without requiring separate systems.
2Ease of operation
If power-assisted trailers are designed with electric wheels, then towing becomes more labor-saving, but it still requires manual effort and cannot carry people
Solution Approach 1:
The folding wagon incorporates an integrated platform design that can accommodate both cargo and passengers. The electric propulsion system provides sufficient power to carry both goods and people, transforming the device from a purely cargo-oriented cart to a versatile personal transport solution. The control system adapts to different load types and weights.
Solution Approach 2:
The folding wagon features a dynamic, reconfigurable structure with foldable components and adjustable elements. The frame can be folded for compact storage and deployed for use, while the platform area can be configured to prioritize either cargo space or passenger seating based on immediate needs. This dynamic adaptability enables the same structure to serve multiple functions.
3Adaptability or versatility
If electric wheels and control devices are added to the folding wagon, then it becomes more convenient for outdoor activities, but the device complexity increases
Solution Approach 1:
The control assembly integrates multiple functions into a single unified system. The control device manages electric propulsion, steering, braking, and folding operations through a centralized interface. This integration reduces the number of separate components and controls the user must manage, making the complex system easier to operate while maintaining full functionality for outdoor activities.
Solution Approach 2:
The folding mechanism employs a nested structure where components are arranged to fold within each other. The electric wheels, control assembly, and frame elements are configured to nest compactly when folded, minimizing the space required for storage and transport. This nested arrangement manages the complexity of multiple moving parts by organizing them in a space-efficient manner.
