Stand-on Mower Operator Station Dampening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stand on mowers lack effective solutions to improve operator comfort, reduce vibration and shock, and minimize operator leaning during use, despite efforts like spring-mounted foot platforms and pivoting designs.
Innovation Solution
A stand on mower operator station featuring a leaning pad with a dampening member, such as a coil spring over shock absorber, connected to the vehicle frame for shock absorption, and pivot arms for stabilizing vertical motion, along with a foot platform that can pivot and provide limited vertical movement, enhancing comfort and reducing impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spring-mounted foot platforms and pivoting designs are used, then operator comfort is improved, but vibration and shock transmission to the operator increases
Solution Approach 1:
The patent applies beforehand cushioning by positioning the dampening member between the leaning pad and the frame to preemptively absorb shock and vibration before these harmful factors can be transmitted to the operator. The dampening member acts as a pre-configured cushioning element that mitigates impact forces during operation, directly addressing the contradiction by reducing vibration transmission while maintaining the comfort benefits of the spring-mounted and pivoting designs
2Stability of the object's composition
If rigid leaning pads are used, then structural stability is maintained, but operator comfort and shock absorption deteriorate
Solution Approach 1:
The patent applies dynamics by transitioning the leaning pad from a rigid, fixed structure to a dynamic system that can move and absorb energy. The dampening member enables the leaning pad to dynamically respond to operational conditions by allowing controlled movement and energy dissipation, thereby improving operator comfort while maintaining structural stability through the dampening mechanism
3Object-affected harmful factors
If dampening members are added to the leaning pad, then shock absorption improves, but device complexity increases
Solution Approach 1:
The patent applies taking out by extracting the shock absorption function into a separate, dedicated dampening member that is integrated between the leaning pad and the frame. This separation allows the dampening function to be added without fundamentally redesigning the entire operator station, thereby improving shock absorption while minimizing the increase in overall device complexity through modular integration
