Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terrain vehicles face challenges with high weight, lack of level compensation for smooth ride on uneven terrains, and limited adjustability to traverse varying obstacles, leading to inefficient power transfer and energy consumption.
Innovation Solution
A vehicle design featuring a chassis with pivoting left and right frames connected by a pivot joint, offset wheel pairs, and adjustable wheel displacement units, along with a base plate levelling unit and a second level compensation system for maintaining a level seat foundation, allowing for adaptable traversal of different terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple serially connected wheel pairs are used to provide grip when ascending stairs, then traction is improved, but the vehicle becomes bulky and difficult to maneuver in narrow passages
Solution Approach 1:
The vehicle divides the wheel assembly into multiple independent wheel pairs (front wheel pair and rear wheel pair) that can operate semi-independently. Each wheel pair can be positioned optimally for different terrain conditions, providing reliable traction without requiring a single large complex wheel assembly.
Solution Approach 2:
The invention utilizes the vertical dimension by allowing the wheel pairs to be positioned at different heights and the seat to pivot around a horizontal axis. This enables the vehicle to maintain a compact horizontal footprint while achieving effective stair-climbing capability through vertical wheel placement and seat rotation.
2Stability of the object's composition
If heavy materials are used to provide stability for large payload, then vehicle stability is improved, but weight increases limiting elevator access and requiring more propelling energy
Solution Approach 1:
The vehicle employs an asymmetric frame structure with the left and right frames extending perpendicular to the rotational axis at different positions. This asymmetric configuration provides stable support for the payload while distributing weight efficiently, avoiding the need for excessive weight to achieve stability.
Solution Approach 2:
The vehicle uses a dynamic seat mounting system that allows the seat to pivot around a horizontal rotational axis. This dynamic adjustment capability enables the vehicle to maintain stability across varying terrains and payload conditions without requiring a heavy fixed structure, as the system adapts its configuration to maintain balance.
3Reliability
If the vehicle is optimized for traversing specific staircase dimensions, then performance on that terrain is improved, but the vehicle lacks adaptability to other obstacles with varying dimensions
Solution Approach 1:
The vehicle incorporates multiple adjustable parameters including wheel pair spacing, wheel size, and seat pivot position. These dynamic adjustments allow the vehicle to optimize its configuration for different terrain types and obstacle dimensions, maintaining reliable performance across diverse environments rather than being fixed for a single terrain type.
Solution Approach 2:
The vehicle design integrates multiple functions into a single platform: it can traverse flat terrain, climb stairs of various dimensions, and navigate obstacles by adjusting wheel pair configuration and seat position. This multi-functional capability allows one vehicle to replace several specialized vehicles, achieving versatility without sacrificing terrain-specific performance.
4Device complexity
If fixed wheel configuration is used to simplify vehicle structure, then device complexity is reduced, but the vehicle cannot efficiently traverse varying obstacles with different dimensions
Solution Approach 1:
The vehicle divides the wheel system into separable wheel pairs that can be independently positioned and configured. This segmentation allows relatively simple adjustment mechanisms to achieve multiple configurations, rather than requiring a completely fixed complex structure or a fully reconfigurable system, thus balancing simplicity with adaptability.
