Removable Chock Base and Interlocking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for securing items like coolers and storage containers on flat surfaces are permanently mounted, creating trip hazards and aesthetic issues when not in use, as they require screws and leave holes in the surface.
Innovation Solution
A two-piece base and chock assembly with interlocking features that allow for tool-free installation and removal, using a low-profile L-shaped base with channels and recessed depressions for secure attachment without mechanical fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanently mounted chocks are installed using multiple screws, then secure item retention is achieved, but the surface is damaged with multiple holes and creates trip hazards when not in use
Solution Approach 1:
The chock assembly is divided into two separate components: a base that remains permanently mounted to the surface, and a chock that can be removed when not in use. This segmentation allows the secure retention function to be maintained when needed while eliminating the trip hazard and surface damage issues when the chock is removed.
Solution Approach 2:
The chock portion is extracted as a removable component from the permanently mounted base. This allows the chock to be taken out when not needed, eliminating the harmful effects of having permanent obstructions on the surface while maintaining the secure retention capability when the chock is in place.
2Reliability
If permanently mounted chocks are installed using multiple screws, then secure item retention is achieved, but removal requires removing screws and exposing holes in the surface
Solution Approach 1:
By segmenting the chock assembly into a permanent base and a removable chock, the system allows easy removal of just the chock portion without needing to remove screws or damage the surface, while maintaining secure retention when assembled.
Solution Approach 2:
The base acts as an intermediary component that remains mounted to provide support and positioning, while the chock serves as the removable element that provides the retention function. This intermediary base allows the chock to be easily installed and removed without affecting the permanent mounting.
3Reliability
If large L-shaped chocks are permanently installed at four corners, then item retention is achieved, but the device creates aesthetic issues and trip hazards when items are removed
Solution Approach 1:
The chock is segmented into a low-profile base that remains mounted and a removable chock portion. When the chock is removed, only the low-profile base remains, which minimizes trip hazards and improves aesthetic appearance while maintaining the capability for secure retention when needed.

AI summary
A removable chock for securing coolers, storage bins, and tool boxes on boats, and cargo areas of vehicles and trailers and the like. The low-profile base mounts to any flat surface, and allows the chock to be installed and uninstalled from the base without the use of any tools. The chock can be removed from the base when not being used and the base remains installed. The low-profile design of the base greatly reduces the potential trip hazard, as well as offers an aesthetically pleasing appearance than a permanently installed chock.
