Adjustable Weight Support Apparatus for Limited Chassis Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automotive settings, the limited space under the chassis of high-performance vehicles often prevents the proper placement of jack stands due to the occupation by lifting devices, posing hazards to the vehicle and personnel.
Innovation Solution
An adjustable weight supporting apparatus featuring a vertical member, leg, and horizontal member with adjustable depth and length settings, allowing for flexible placement and disassembly for convenient storage, which can be used with limited clearance spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a hydraulic floor jack is used for lifting, then the lifting function is achieved, but the space under the chassis is occupied preventing jack stand placement
Solution Approach 1:
The weight supporting apparatus is divided into separable components including a horizontal member, vertical member, and leg assembly that can be independently positioned and adjusted, allowing the system to adapt to limited spaces while maintaining lifting capability
Solution Approach 2:
The apparatus incorporates adjustable leg depth and horizontal member positioning capabilities, enabling dynamic adaptation to different clearance requirements and space constraints under various vehicle chassis configurations
2Reliability
If jack stands are placed in designated spaces, then vehicle safety is improved, but the space is already occupied by lifting devices
Solution Approach 1:
The apparatus extends the support structure vertically with adjustable leg depth, utilizing the vertical dimension to achieve proper support positioning without requiring additional horizontal space that would conflict with lifting device placement
Solution Approach 2:
The horizontal member acts as an intermediary component that distributes weight and provides attachment points for vertical support members, enabling safe weight bearing in configurations that accommodate limited space under the chassis
3Adaptability or versatility
If an adjustable weight supporting apparatus is used, then adaptability to limited clearance is improved, but device complexity increases
Solution Approach 1:
The leg assembly features nested components with telescoping sections that can be inserted to varying depths, allowing compact storage when not in use while providing extended reach and adjustment capability during operation
Solution Approach 2:
The apparatus incorporates adjustable parameters including leg depth, horizontal member positioning, and cuff location, enabling adaptation to different clearance requirements and vehicle types without requiring multiple specialized devices

AI summary
An adjustable weight supporting apparatus is provided with a horizontal member, vertical member and legs. The weight supporting apparatus may be used to support the weight of an automobile or other object. The horizontal member may be placed on a lifting device, which may be lifted to contact an object. Legs and the vertical member may be added to the horizontal member to support the weight without a lifting force, which may be temporarily fixed in place with one or more pin. The horizontal member may include an elongated portion and a cuff. Various aspects of the apparatus may be adjusted to support a desired object at a desired height and/or footprint to provide sufficient access under the object.
