Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the track-type robot uses a fixed running mechanism on a horizontal track, then the structure is simple, but the robot cannot perform uphill and downhill movements

Engineering Contradiction:
Improveterrain adaptabilityVSAvoidrunning mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The running mechanism is designed with a pivoting element that allows dynamic adjustment of the running mechanism's orientation. This enables the robot to adapt to inclined tracks by pivoting the running mechanism to maintain proper contact angles, thereby achieving uphill and downhill capabilities without fundamentally changing the overall structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The running mechanism is divided into separable components including the pivoting element, drive wheels, and positioning wheels. This segmentation allows each component to be optimized independently for specific functions while maintaining overall system simplicity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the track-type robot makes a sharp turn, then the turning angle is large, but the wheels offset due to centrifugal factors causing the robot to fail to corner or disengage from the track

Engineering Contradiction:
Improveturning capabilityVSAvoidtrack engagement stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The positioning wheels are designed to be adjustable and adaptable during turning operations. They can dynamically adjust their position and pressure on the track to counteract centrifugal forces during sharp turns, maintaining reliable track engagement while enabling large turning angles.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The positioning wheels apply preliminary counteracting forces before the robot fully enters a turn. By positioning these wheels to press against the track in advance during turning maneuvers, the system prevents wheel offset and maintains stable track engagement throughout the turning process.

Inventive Principle:
Principle #9Preliminary anti-action

3Ease of operation

If the track-type robot adds a pivoting element and support restoring device, then the robot can go uphill and downhill smoothly, but the device complexity increases

Engineering Contradiction:
Improveoperation smoothnessVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pivoting element provides dynamic adaptation to track inclines, automatically adjusting the running mechanism's orientation to maintain smooth operation on uphill and downhill sections. This single dynamic component achieves the desired operational smoothness without requiring multiple complex mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support restoring device functions as a counterbalancing mechanism that compensates for the effects of gravity on inclined tracks. By providing restoring forces that counteract gravitational influence, the device enables smooth operation on slopes while maintaining a relatively simple structure.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

AI summary

The present invention relates to a track-type robot, wherein at least one drive wheel is driven by a driving device disposed on a body to drive a running mechanism to travel on a track, so as to drive the track-type robot forward; when the track-type robot goes uphill or downhill, the running mechanism and the body perform relative deflection motions in forward and reverse directions through a pivoting element connecting the running mechanism with the body, in the forward and reverse axial rotating directions thereof, so the running mechanism and the drive wheel keep contact with the track when the track-type robot goes uphill and downhill. When the track-type robot makes a turn, positioning wheels disposed on side edges of the track are pushed by the holding mechanisms to counteract a centrifugal offset force generated, so that the track-type robot provided by the present invention is avoided from the situation of left and right swinging; and at the same time, a braking device located on at least one side of the drive wheel interferes in traveling of the drive wheel in the operation process of the track-type robot, so as to achieve the purpose of temporary braking.
