Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension systems struggle to maintain the horizontal posture of vehicles and robots when traveling on uneven surfaces such as curved or inclined terrains, leading to instability and potential cargo loss.
Innovation Solution
A rotary disc suspension system is introduced, comprising an inner disc rotatably coupled to the vehicle body and an outer disc coupled to the wheel, converting linear motion into rotational motion through a support shaft and connection shaft arrangement, with a bearing and actuator system for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional suspension systems (shock absorbers, springs, suspension arms) are used, then the vehicle can absorb impacts from road surfaces, but the vehicle body shakes severely on uneven terrains with curves or slopes
Solution Approach 1:
The patent employs a rotary disc suspension system where the disc can rotate dynamically to adapt to uneven terrain. The disc rotates about its center axis, allowing the vehicle body to maintain a horizontal state while the wheels contact irregular surfaces, thereby providing active stabilization rather than passive shock absorption.
Solution Approach 2:
The invention introduces a rotational degree of freedom about the vertical axis, adding a new dimension of motion control. This rotational capability allows the suspension system to counteract tilting and shaking forces by rotating the disc in response to terrain variations, maintaining vehicle body stability independently of wheel position.
2Adaptability or versatility
If the vehicle travels on curved or inclined surfaces, then the vehicle can navigate various terrains, but the vehicle body tilts and cannot maintain horizontal posture
Solution Approach 1:
The rotary disc suspension system dynamically rotates to counteract terrain-induced tilting. When the vehicle encounters curved or inclined surfaces, the disc rotates about its vertical axis to keep the vehicle body horizontal, adapting in real-time to maintain stable posture while navigating diverse terrains.
Solution Approach 2:
The rotating disc acts as a counterbalancing mechanism that generates opposing rotational forces to counteract the tilting moments caused by uneven terrain. This active counterbalancing maintains the vehicle body's horizontal posture despite external gravitational and inertial forces.
3Adaptability or versatility
If delivery robots move on uneven ground, then the robots can deliver goods to various locations, but the carrier cannot maintain level position causing food spills
Solution Approach 1:
The delivery robot's carrier incorporates a rotary disc suspension system that rotates dynamically to maintain the carrier's level position. As the robot navigates uneven ground to reach various delivery locations, the disc rotates to counteract tilting forces, ensuring the carrier remains horizontal and preventing food spills.
4Adaptability or versatility
If the vehicle body is allowed to tilt on uneven surfaces, then the suspension can adapt to terrain variations, but cargo may fall out due to severe shaking
Solution Approach 1:
The rotary disc suspension system provides dynamic stabilization by rotating to counteract terrain-induced shaking while maintaining vehicle body horizontality. This active stabilization ensures cargo retention by preventing severe shaking, unlike conventional suspensions that allow excessive body movement to adapt to terrain.

Function Achieved in This Case
The rotary disc suspension system effectively maintains the horizontal state of the vehicle body across varying terrain, reducing the risk of cargo loss and enhancing stability by actively responding to dynamic strain and stress.
Implementation Method 1

AI summary
The present invention relates to a rotary disc suspension system for connecting different components constituting a moving body, comprising: an inner disc rotatably connected to one component of the moving body; and an outer disc which is coupled to another component of the moving body and which is rotatably coupled to the inner disc while disposed to face the inner disc, and thus force applied to the moving body during traveling is converted into rotational motion from linear motion so that dynamic strain and dynamic stress of the moving body can be more actively managed, and thus, even if the moving body encounters bumpy and rugged land or sloped land when in motion, a horizontal state can be maintained without tilting.
