Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual wheel drive means are installed within the vehicle body, then each wheel can be independently controlled for various movement modes, but the vehicle body space is occupied and the internal layout is interfered with
Solution Approach 1:
The wheel drive means is nested within the wheel structure itself, specifically utilizing the inner cavity of the wheel body to house the motor and transmission components. This nesting approach allows the drive system to be integrated into the wheel without occupying additional space within the vehicle body, thereby maintaining independent wheel control capability while avoiding interference with the vehicle's internal layout.
Solution Approach 2:
The invention relocates the wheel drive means from the traditional longitudinal dimension (within the vehicle body) to the radial dimension (within the wheel structure). By positioning the motor and gear set within the wheel's inner cavity and extending the drive shaft axially, the system achieves independent wheel control without consuming valuable vehicle body space, effectively utilizing the wheel's own volume.
2Adaptability or versatility
If large-diameter wheels with in-wheel motors are used, then independent wheel drive is achieved, but the overall vehicle size increases
Solution Approach 1:
The motor and transmission components are nested within the existing wheel structure, utilizing the inner cavity space rather than adding external protrusions. This integration ensures that the wheel drive means does not increase the overall vehicle dimensions, as the drive components are contained within the wheel's existing footprint.
Solution Approach 2:
The drive system is arranged in the radial dimension of the wheel rather than extending the vehicle's longitudinal dimension. The motor shaft extends axially through the wheel, and the drive components are positioned within the wheel's depth, effectively using the wheel's own volume without increasing the vehicle's overall length or width.
3Power
If wheel drive means are mounted within the vehicle body, then power transmission to wheels is achieved, but the internal layout of the vehicle body is interfered with
Solution Approach 1:
The wheel drive means is extracted from the vehicle body and relocated to the wheel structure itself. By removing the motor and transmission components from the vehicle body's internal space and integrating them into the wheel, the invention eliminates interference with the vehicle body's internal layout while maintaining full power transmission capability through the wheel's own mounting structure.
Solution Approach 2:
The wheel structure itself serves as the mounting platform and housing for the drive means, eliminating the need for separate vehicle body mounting structures. The wheel's inner cavity provides the housing space, and the wheel's axial extension provides the mounting interface, allowing the wheel to serve its own drive system without requiring additional vehicle body infrastructure.
