Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional robotic vehicles use fixed rigid structures, then manufacturing and control are simplified, but adaptability to environments with changing geometries deteriorates

Engineering Contradiction:
Improveadaptability to changing geometriesVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The robotic vehicle is divided into multiple modular sections along its longitudinal axis, each with independent drive members. This segmentation allows different sections to move independently, enabling the vehicle to adapt to varying geometries while maintaining manageable complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vehicle transitions from a fixed rigid structure to a dynamic reconfigurable structure where sections can change relative positions and orientations. The flexible connections and independent drive members enable the structure to dynamically adapt its shape to match environment geometries

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If conventional robotic vehicles use omnidirectional movement capability, then navigation flexibility is improved, but acceleration performance in varying environments deteriorates

Engineering Contradiction:
Improvenavigation flexibilityVSAvoidacceleration performance
Core Design Contradiction:
Ease of operationVSSpeed

Solution Approach 1:

Different sections of the vehicle have drive members with locally optimized characteristics. Sections can selectively activate specific drive members based on local environmental conditions, enabling accelerated response to varying geometries while maintaining overall navigation flexibility

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The vehicle employs dynamic control of drive members where sections can independently adjust their movement patterns. This dynamic response allows the vehicle to accelerate efficiently when encountering changing geometries rather than relying on fixed omnidirectional movement patterns

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If drive members selectively drive one section of the flexible ring, then differential movement and steering are enabled, but control system complexity increases

Engineering Contradiction:
Improvedifferential movement capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system is segmented to match the physical segmentation of the vehicle, with each section having its own drive members that can be independently controlled. This modular control architecture enables differential movement while keeping control complexity manageable through distributed control

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each section's drive members are capable of self-regulation and autonomous operation to a degree, reducing the burden on the central control system. The sections can independently adjust their movement based on local conditions, simplifying overall control while maintaining differential movement capability

Inventive Principle:
Principle #25Self-service
