Resilient Jack Foot Pad with Receptacles for RV Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jack systems for recreational vehicles lack efficiency in supporting and leveling the vehicles, as they often fail to provide adequate traction and insulation from environmental elements.
Innovation Solution
A foot pad made of resilient and flexible material is designed to be releasably secured to the jack foot of a vertically adjustable jack, featuring a pair of opposite facing receptacles and top ledges that allow the jack foot to be securely positioned and provide traction and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional jack foot is used, then the jack structure is simple, but the traction and insulation performance are insufficient
Solution Approach 1:
The foot pad is divided into multiple functional segments: a base portion for insulation, receptacles for securing the jack foot, and ledges for positioning. This segmentation allows each part to perform its specific function optimally while maintaining overall simplicity.
Solution Approach 2:
The foot pad acts as an intermediary component between the jack foot and the ground. It provides both traction through its base portion and insulation from environmental elements, while the receptacles and ledges serve as intermediary structural features for secure attachment.
2Adaptability or versatility
If the foot pad uses resilient and flexible material, then the attachment is secure and adaptable, but the manufacturing complexity increases
Solution Approach 1:
The foot pad utilizes changes in material parameters - specifically using resilient and flexible materials that can deform to accommodate the jack foot geometry. This allows the same foot pad design to adapt to variations in jack foot dimensions while maintaining secure attachment.
Solution Approach 2:
The foot pad employs a flexible material body that can conform to the jack foot shape. The flexibility allows the receptacles and ledges to be formed as integral parts of the material rather than requiring separate assembly, simplifying manufacturing while maintaining adaptability.
3Manufacturing precision
If the foot pad includes receptacles and ledges, then the positioning precision is improved, but the device complexity increases
Solution Approach 1:
The receptacles and ledges are merged into a single integrated foot pad structure rather than being separate components. This combining approach achieves precise positioning functionality while reducing assembly complexity and the number of parts that need to be manufactured and assembled.
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 foot pad enhances the stability and traction of the jack system, allowing for better support and leveling of recreational vehicles while also providing insulation from environmental elements.
Implementation Method 1
The resilient and flexible material of the foot pad is configured to be deflected to allow the opposite ends of the jack foot to be positioned within the pair of opposite facing receptacles and the pair of opposite facing receptacles then resiliently returning to an original shape of the foot pad.
