Truck Step Addition Apparatus with Nested Modular Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truck accessory devices do not provide additional step heights as intermediate steps for easier entry and exit from tall trucks, as they are designed as replacement or standalone steps rather than add-ons to existing truck steps.
Innovation Solution
A truck step addition apparatus comprising a lower block and an upper block with mounting apertures and hardware sets to secure the blocks to a truck step, along with a grip plate for improved grip, allowing for secure and removable installation as intermediate steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If replacement or standalone truck steps are used, then the device structure is simple, but additional step heights for intermediate steps are not provided
Solution Approach 1:
The apparatus consists of nested blocks where an upper block is positioned on top of a lower block, creating intermediate step heights. The upper block contains a recess that receives the lower block, forming a compact nested structure that provides multiple step levels without requiring separate standalone components.
Solution Approach 2:
The apparatus is divided into separate modular blocks (lower block, upper block, grip plate) that can be independently manufactured and assembled. Each block has standardized mounting apertures allowing for flexible configuration and installation on different truck steps, providing intermediate heights through modular combination.
2Reliability
If secure mounting is provided, then reliability is improved, but ease of installation and removal deteriorates
Solution Approach 1:
Mounting apertures are pre-positioned in each block at standardized locations, and mounting hardware sets are designed to be selectively engageable through these apertures. This preliminary preparation of mounting features allows for both secure attachment and easy removal by simply disengaging the hardware sets without complex tools or procedures.
3Ease of operation
If grip plate with textured surface is added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The grip plate is coupled to the upper block to form an integrated assembly. The textured surface on the grip plate top side provides enhanced grip quality, while the plate mounting apertures allow it to be securely attached to the upper block, combining multiple functions (grip enhancement and structural integration) into a single component.

AI summary
A truck step addition apparatus for easier entry into a tall truck includes a lower block having a plurality of lower mounting apertures extending from a lower top side through a lower bottom side. A plurality of first mounting hardware sets secures the lower block to a truck step of a truck. An upper block is coupled to the lower block and has a plurality of upper mounting apertures extending from an upper top side through an upper bottom side. A grip plate is coupled to the upper block and has a pair of plate mounting apertures extending from a textured plate top side through a plate bottom side. A plurality of second mounting hardware sets secures the grip plate to the upper block, the upper block to the lower block, and the lower block to the truck step of the truck.
