Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional multi-axle vehicle designs are used, then power transmission and cooling systems are well-established, but the vehicle size and weight increase significantly
Solution Approach 1:
The vehicle is divided into modular components mounted on a common cross-member: drive unit, cooler, and spiked rollers are separate interchangeable modules. This allows the power transmission system to be simplified while maintaining functionality, as each module can be optimized independently rather than requiring a complex integrated multi-axle system.
Solution Approach 2:
The cross-member structure serves multiple functions simultaneously: it supports the drive unit, mounts the cooler, positions the spiked rollers, and provides structural rigidity. This multi-functional design eliminates the need for separate structural components required in conventional multi-axle vehicles, reducing overall complexity while maintaining vehicle functionality.
2Reliability
If spiked rollers are used for gripping icy surfaces, then traction is improved, but the mechanism becomes more complex compared to conventional wheels
Solution Approach 1:
The spiked rollers are designed to rotate and engage with the icy surface dynamically, adapting to varying terrain conditions. The rollers can be positioned at different angles and depths, allowing the system to maintain reliable traction on icy surfaces while keeping the mechanism simple through rotational movement rather than complex articulated joints.
Solution Approach 2:
The spiked rollers automatically engage and disengage from the icy surface based on vehicle movement and surface conditions, eliminating the need for complex control systems. The rotation and positioning of rollers is self-regulating, providing reliable traction while minimizing mechanical complexity.
3Volume of moving object
If a compact single-axle design is used, then vehicle size is reduced, but the power transmission from a single drive to multiple rollers becomes more complex
Solution Approach 1:
The cross-member acts as an intermediary structure that distributes power from the single drive unit to multiple spiked rollers. Rather than requiring complex direct drive mechanisms to each roller, the cross-member provides a rigid mounting structure that allows simple power transmission while maintaining precise positioning of all rollers, thus reducing overall transmission complexity.
Solution Approach 2:
Multiple power transmission functions are merged into the single cross-member structure, which simultaneously supports and positions all spiked rollers. This consolidation eliminates the need for separate transmission mechanisms for each roller, reducing complexity while maintaining the compact single-axle design.
