Sliding Undercarriage Frame Layout for Steep-Slope Track Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio-controlled vehicles are unsafe on extreme slopes due to their inability to accommodate larger and heavier motors, which cause the tracks to come out of their seat, leading to instability and risk of rollover.
Innovation Solution
A radio-controlled vehicle design featuring a reinforced frame and undercarriage that can accommodate larger and heavier motors, such as common rail, turbo intercooler motors, while maintaining stability on extreme slopes through a lowered center of gravity and secure track positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If larger and heavier motors (common rail, turbo intercooler) are installed to comply with anti-pollution rules, then emission standards are met, but the vehicle becomes unstable and risks rolling over on extreme slopes
Solution Approach 1:
The patent repositions the motor from a high-mounted position to a low-mounted position within the frame, changing the vertical dimension of motor placement. This dimensional change lowers the center of gravity and shifts the motor's spatial location to improve stability while maintaining emission compliance through the use of larger motors
2Object-generated harmful factors
If larger and heavier motors are installed, then anti-pollution requirements are fulfilled, but the tracks come out of their seat causing standstill and operational interruption
Solution Approach 1:
The motor is relocated to a lower position within the frame structure, changing its vertical placement dimension. This repositioning redistributes the weight load more effectively to the undercarriage and track system, preventing track derailment while enabling the use of larger, cleaner motors that meet emission standards
3Adaptability or versatility
If existing frames and undercarriages are used, then current vehicle operations are maintained, but they cannot accommodate larger and heavier motors
Solution Approach 1:
The frame structure is divided into distinct modular segments including longitudinal members, transverse members, and guide structures. This segmentation allows the frame to be designed with specific load-bearing zones that can accommodate larger motors while maintaining structural integrity and enabling standardized manufacturing of complex components
Solution Approach 2:
The undercarriage is repositioned to a lower dimension within the overall vehicle structure. This dimensional relocation creates space within the frame to accommodate larger motors while the lower undercarriage position provides better structural support and weight distribution for handling heavier motor assemblies
4Reliability
If the center of gravity is lowered, then stability on extreme slopes is improved, but the compactness of the vehicle is reduced
Solution Approach 1:
The motor is nested within the frame structure at a low position, with the undercarriage components arranged around and alongside it. This nesting arrangement accommodates the low center of gravity requirement for stability while efficiently utilizing the available vertical and lateral space to maintain overall vehicle compactness
