Solution Overview
Problem
Existing grounds maintenance vehicles face challenges in efficiently propelling and maneuvering while maintaining effective ground engagement and implement operation, particularly in terms of track tensioning and implement positioning.
Innovation Solution
A track-propelled vehicle design featuring a chassis with a drive sprocket and driven sprocket, a track assembly with adjustable bogey wheels, and a mechanical communication assembly that includes a belt or gear box to transmit torque to an implement, allowing for repositionable implement action and ground contact adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the track assembly uses fixed bogey wheels, then the structure is simple, but the vehicle cannot adjust to different ground conditions and maintain optimal track tension
Solution Approach 1:
The bogey wheels are designed with longitudinal translation capability along the track, allowing them to dynamically adjust their position to maintain optimal track tension and adapt to varying ground conditions. This dynamic adjustment mechanism resolves the contradiction by enabling adaptability while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the implement has a fixed lateral line of action, then the mechanical communication assembly is simple, but the implement cannot be positioned centrally to the ground-contact section for optimal operation
Solution Approach 1:
The implement's lateral line of action is made repositionable through the mechanical communication assembly, allowing it to be adjusted to a central position relative to the ground-contact section. This dynamic repositioning capability enables optimal implement operation while managing the complexity through an integrated adjustment mechanism.
3Reliability
If the vehicle uses a complex tensioning mechanism for the track, then track tension can be precisely maintained, but the overall vehicle structure becomes overly complicated
Solution Approach 1:
The tensioning mechanism is designed to be adjustable by the operator through the repositionable bogey wheels, which can be manually moved to achieve and maintain proper track tension. This self-service approach maintains reliable track tension while avoiding overly complex automated tensioning systems.
