Trailer Jack Block with Central Storage and Rubber Coating
Solution Overview
Problem
Existing trailer jack support systems are heavy, bulky, unstable when stacked, and difficult to clean, especially on messy surfaces, requiring a lightweight, durable, easy-to-assemble, and inexpensive solution for stable support and storage.
Innovation Solution
A jack block and stop with a lightweight internal support structure, flat surfaces for stability, a central open surface for storing the jack components, and a rubberized coating for anti-slip and easy cleaning, allowing for compact storage and easy stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional concrete blocks are used for supporting trailers, then good strength and stability are provided, but weight and bulk increase making them heavy and not user friendly from storage standpoint
Solution Approach 1:
The jack block is constructed from composite materials including a rigid core structure (providing strength) encased in a rubberized coating (providing durability and ease of cleaning). This composite construction achieves the required support strength while reducing overall weight and bulk compared to solid concrete blocks.
2Strength
If multiple blocks are stacked to support certain objects, then support capability is increased, but stability deteriorates creating an unstable condition
Solution Approach 1:
The jack block is designed as a single integrated unit with a through-opening that allows the jack crank to pass through and be retained on the jack body. This segmentation of function (support + storage + stabilization) eliminates the need to stack multiple blocks, thereby maintaining stability while providing increased support capability.
3Strength
If traditional blocks are used on messy ground surfaces, then support function is provided, but cleaning difficulty increases requiring cleaning prior to storage
Solution Approach 1:
The jack block is encased in a rubberized coating that forms a flexible, non-porous shell. This coating prevents mud and debris from penetrating into the block structure, making the block easy to clean by simply wiping or rinsing the surface, unlike traditional porous concrete or wood blocks that absorb contaminants.
4Volume of moving object
If jack block is designed with compact storage space on trailer jack, then storage convenience is improved, but device complexity increases
Solution Approach 1:
The jack block serves multiple functions simultaneously: (1) provides structural support for the trailer, (2) stores the jack crank and stem when not in use through the through-opening, (3) acts as a wheel stop when positioned appropriately, and (4) protects the jack components from damage. This multi-functionality achieves compact storage without increasing structural complexity.

AI summary
A jack block and stop for a trailer includes an internal relatively lightweight support structure, a bottom surface having a relatively flat aspect to provide stable support when weight is applied on said jack block and stop, an upper surface having relatively flat aspect and a central open surface entirely extending through from said upper surface to said bottom surface which is large enough to at least part of a trailer part to retain said jack block thereabout in a stored mode.
