Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position controlling devices for loading platforms in mobile objects, such as vehicles, lack effective mechanisms to absorb inertial forces and maintain stable positioning during vehicle movements, leading to discomfort and instability for occupants or cargo.
Innovation Solution
A position controlling device that includes a loading platform with a coupling portion featuring a restoring member, a guide portion, and a spherical surface, allowing the loading platform to move relative to its base while the restoring member attenuates inertial forces, thereby maintaining stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the loading platform is rigidly fixed to the base portion, then positioning stability is improved, but inertial forces during vehicle movement cannot be absorbed, causing discomfort and instability
Solution Approach 1:
The coupling portion is designed to enable dynamic relative movement between the loading platform and base portion. The spherical surface allows rotational movement while the guide portion constrains the movement direction, creating a dynamic system that can adapt to inertial forces during vehicle acceleration, deceleration, and turning while maintaining stable positioning through controlled motion rather than rigid fixation.
Solution Approach 2:
The spherical surface is specifically designed to allow the loading platform to rotate relative to the base portion in response to inertial forces. The curved surface geometry enables multi-directional movement while maintaining contact, allowing the system to absorb shocks and inertial forces through controlled rotational motion rather than rigid resistance.
2Object-affected harmful factors
If the loading platform allows free movement to absorb inertial forces, then ride comfort is improved, but positioning stability deteriorates
Solution Approach 1:
The coupling system is segmented into distinct functional components: the spherical surface for rotational movement, the guide portion for directional constraint, and the restoring member for position maintenance. This segmentation allows each component to perform its specific function - the spherical surface absorbs inertial forces through rotation while the guide portion and restoring member work together to maintain positioning stability, resolving the contradiction between movement freedom and stability.
Solution Approach 2:
The coupling portion acts as an intermediary mechanism between the rigid base portion and the loading platform. It mediates the interaction between stability requirements and inertial force absorption by providing controlled rotational movement through the spherical surface while constraining excessive displacement through the guide portion, thus allowing both stability and comfort to coexist.
3Object-affected harmful factors
If a complex mechanism is added to absorb inertial forces, then ride comfort is improved, but device complexity increases
Solution Approach 1:
The spherical surface provides an elegant and simple geometric solution for absorbing inertial forces. Instead of complex active control mechanisms, the patent uses the inherent properties of spherical geometry to enable passive rotational movement that naturally responds to inertial forces during vehicle acceleration, deceleration, and turning, achieving ride comfort with minimal mechanical complexity.
Solution Approach 2:
The coupling system is designed to automatically respond to inertial forces without requiring external control systems. The spherical surface and guide portion work together to enable self-adjusting movement that passively absorbs shocks and inertial forces, while the restoring member automatically returns the loading platform to its original position, eliminating the need for complex active control mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively absorbs inertial forces and maintains stable positioning of the loading platform during vehicle movements, enhancing ride comfort and stability for occupants or cargo.
Implementation Method 1
The restoring member generates a restoring force for restoring the coupling portion to its original length when the coupling portion is extended
Implementation Method 2
One of the upper part of the base portion and the lower part of the loading portion includes a spherical surface that is convex downward, and the other one includes a guide portion. The guide portion guides the base portion and the loading portion such that the base portion and the loading portion are movable relative to each other in a direction along the spherical surface
