Solution Overview

Problem

There is a need for a secure and efficient method to store and transport coil racks in close proximity to a semi-truck trailer, particularly beneath the trailer deck, to securely stow and haul multiple coil racks for use as chocks to secure steel coils, while ensuring safety and ease of loading and unloading.

Innovation Solution

A coil rack carrier with elongate guide members forming channels and support platforms that allows for quick and efficient loading of coil racks two-by-two and back-to-back, mounted to the trailer's main frame, with rear guide members acting as stops to secure the racks in place beneath the deck.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If coil racks are stored beneath the trailer deck, then safety is improved and coil racks are kept out of sight, but access and retrieval become more difficult

Engineering Contradiction:
ImprovesafetyVSAvoidaccess and retrieval
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a carrier system with guide members and support platforms as an intermediary mechanism between the trailer deck and coil racks. This carrier facilitates easy loading and unloading of coil racks two-by-two and back-to-back, resolving the contradiction by providing both secure storage beneath the deck and efficient access when needed

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If multiple coil racks are stored in close proximity beneath the trailer, then space utilization is improved, but loading and unloading efficiency decreases

Engineering Contradiction:
Improvenumber of coil racks storedVSAvoidloading and unloading efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The carrier is segmented into multiple channels formed by guide members, with each channel capable of receiving coil racks in an organized sequence. This segmentation allows multiple coil racks to be stored efficiently while maintaining easy access through the structured channel system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carrier with pre-configured guide members and support platforms prepares the storage space in advance, allowing coil racks to be quickly loaded and unloaded two-by-two and back-to-back without requiring complex manual positioning during the loading/unloading process

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If coil racks are secured firmly in place, then stability is improved, but ease of loading and unloading decreases

Engineering Contradiction:
Improvestability of coil racksVSAvoidease of loading and unloading
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The carrier system provides a dynamic solution where coil racks can be easily inserted and removed during loading and unloading, then firmly secured in place through the guide members and support platforms. The system transitions from a static securement concept to a dynamic process that accommodates both ease of operation and stability

Inventive Principle:
Principle #15Dynamics

AI summary

A coil rack carrier for guiding and carrying a plurality of coil racks includes a pair of upstanding front guide members laterally spaced apart from one another and a pair of upstanding rear guide members laterally spaced apart from one another. Each rear guide member defines a length that is greater than a length of each front guide member. One of the pair of rear guide members is rearwardly adjacent a first one of the front guide members so as to define a first channel therebetween. Similarly, another of the pair of rear guide members is rearwardly adjacent a second one of the front guide members so as to define a second channel therebetween. For stowage the plurality of coil racks is sequentially received into the first and second channels.
