Wheel Wind Deflector Lever Gear With Integrated Overload Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lever systems for wheel wind deflectors lack cost-effective overload protection, leading to potential damage during exceptional events, as integrating protection mechanisms increases complexity and costs.
Innovation Solution
A lever system with a first and second lever connected by articulation, featuring a ball in a sleeve, a spring, and a support, allowing the ball to guide along the outer contour of the second lever in overload situations, enabling the system to yield without damage, with a connection clip acting as a stop and an actuator securing the first lever to a plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an overload protection mechanism is integrated into the lever system, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The overload protection function is merged into the existing articulation structure by integrating a ball, sleeve, and spring mechanism directly into the connection between levers. This combines the articulation and overload protection into a single integrated component rather than adding a separate protection system.
Solution Approach 2:
The overload protection mechanism is designed to be self-actuating through the spring-loaded ball that automatically engages or disengages based on applied forces. The system monitors and responds to overload conditions without requiring external sensors, controllers, or additional actuation systems.
2Reliability
If an individual coupling or displacement actuator with overload protection is provided, then the reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The overload protection uses simple, inexpensive mechanical components (ball, sleeve, spring) that can be manufactured at low cost. These components are designed to be replaceable if needed, rather than protecting expensive actuators or complex systems.
Solution Approach 2:
The patent replaces electronic or complex mechanical overload protection systems with a simple passive mechanical spring-loaded ball mechanism. This eliminates the need for sensors, controllers, or complex actuation systems while providing reliable overload protection.
3Reliability
If additional system or structural spatial requirements are added for overload protection, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The ball and spring mechanism is nested within the existing articulation structure between the levers. The sleeve contains the ball and spring assembly, which fits within the spatial envelope of the existing joint, adding no significant external dimensions to the system.
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 provides reversible actuation and adaptation to different loads, allowing the lever system to absorb overload without damage, maintaining functionality and reducing costs by using a sliding coupling that can return to its initial state without maintenance.
Implementation Method 1
the articulation has at least one ball (4) in a sleeve (3), a spring (5) and a support (13)
