Adjustable Chock Device with Telescopic Rod for Tire Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chock designs fail to accommodate tires of different widths and prevent hoses or wires from getting caught between the chock and the tire during vehicle maintenance.
Innovation Solution
A chock device comprising a pair of triangular chock bodies mechanically coupled via a telescopic adjustment rod, allowing for adjustable distance and a curved profile to fit various tire sizes, along with a smooth concave profile to guide hoses and cords around the tire, and a non-slip base for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size chock body is used, then the chock can be simple in structure, but it cannot accommodate tires of different widths
Solution Approach 1:
The chock body incorporates a telescopic adjustment rod that can be extended or retracted to change the width of the chock, allowing it to adapt to different tire widths. This dynamic adjustment mechanism transforms a static structure into a variable one, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The telescopic adjustment rod is nested within the chock body structure, with the rod containing inner and outer telescopic sections. This nesting arrangement allows the adjustment mechanism to be compact when not in use while providing extended functionality when needed, maintaining structural simplicity while enabling adaptability.
2Object-affected harmful factors
If a standard chock design is used, then manufacturing is simple, but hoses or wires get caught between the chock and tire
Solution Approach 1:
The chock body features a concave curved surface specifically at the tire-contact region, while other parts maintain simple geometric forms. This localized modification creates a hose-guiding channel that prevents entanglement without requiring complete redesign of the entire chock structure, thus maintaining ease of manufacture while eliminating the harmful effect.
3Adaptability or versatility
If adjustable components are added to accommodate different tire widths, then versatility improves, but device complexity increases
Solution Approach 1:
The telescopic adjustment rod serves multiple functions: it adjusts the chock width to fit different tires, provides structural support, and maintains the rigid framework. By making this single component multi-functional, the design achieves adaptability without proportionally increasing overall device complexity.

AI summary
The present invention relates to a chock device comprising a pair of chock bodies, wherein the chock body has a triangular profile defined by a first side, a second side, and a third side, wherein the first side has a curved profile to receive and snugly fit with a tire of a vehicle thereon; the second side is a base of the chock body having a substantially flat surface; and the third side is an operative rear side of the chock body having a smoothened concave profile. The chock devices further comprises an adjustment rod disposed operatively between the pair of chock bodies to mechanically couple the pair of chock bodies, the adjustment rod having a telescopic configuration.
