Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transport has a fixed wheelbase design, then the structure is simple and stable, but it cannot navigate obstacles or uneven terrain effectively
Solution Approach 1:
The patent applies the dynamics principle by making the wheelbase adjustable through a telescoping mechanism. The undercarriage frames can extend or retract to change the distance between wheels, allowing the transport to adapt its wheelbase dynamically based on terrain conditions. This enables effective navigation of obstacles while maintaining a relatively simple overall structure.
Solution Approach 2:
The transport structure is divided into separate modular components including undercarriage frames, carrier frames, and guidance frames that can move independently. The undercarriage frames are detachably connected to the carrier frames, allowing segmentation of the structure for easier adjustment and reconfiguration to handle different terrain challenges.
2Ease of operation
If the transport uses a fixed undercarriage configuration, then manufacturing is simple, but it lacks maneuverability for heavy loads
Solution Approach 1:
The undercarriage frames are designed with adjustable positioning capabilities, allowing them to be reconfigured during operation. The detachable connections and movable components enable the undercarriage to be adjusted for different load conditions and terrain, improving maneuverability without requiring complete redesign during manufacturing.
Solution Approach 2:
The transport design incorporates multi-functional components that can serve multiple purposes. The undercarriage frames can be positioned in different configurations to handle various load types and terrains, while the guidance frames provide both steering and stability functions, reducing the need for separate specialized components.
3Reliability
If the transport has a rigid frame structure, then it maintains stability, but it cannot adjust to uneven terrain or minimize friction
Solution Approach 1:
The patent implements dynamic adjustment capabilities where the undercarriage frames can be repositioned and the wheelbase can be extended or retracted. This allows the rigid frame structure to adapt to uneven terrain by adjusting the spacing and positioning of support points, maintaining stability while accommodating terrain variations.
Solution Approach 2:
The transport allows changing key geometric parameters such as wheelbase length and undercarriage positioning. These parameter adjustments enable the structure to adapt to different terrain conditions while maintaining stability, as the rigid frames can be reconfigured to optimal positions for various operating conditions.

AI summary
A portable utility transport adaptable to multiple wheel and axel combinations. The wheelbase is adjustable and the undercarriage is pivotal permitting them to fold under the carrier frame in a stowed orientation. The elongated guidance frame creates a lever utilizing the rolling fulcrum over the front or rear wheels. The guidance frame is pivotally attached to the carrier frame allow it to be laid virtually flat upon the carrier frame.
