Solution Overview

Problem

Current tire storage solutions for large tires face challenges such as inefficient batch control, First In First Out (FIFO) control, ergonomic risks, and deformation due to static storage, requiring large spaces and equipment like forklifts, which are costly and pose handling risks.

Innovation Solution

A tire storage device with interconnected ramps and specific inclinations allows tires to enter and exit from the same side, utilizing gravity for movement and incorporating a semi-automatic elevator system for controlled inlet and outlet, ensuring FIFO sequencing and minimizing deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If horizontal storage is used, then large areas are required, but storage capacity per unit area is limited and FIFO control is not guaranteed

Engineering Contradiction:
Improvestorage capacityVSAvoidstorage area
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent transitions from horizontal storage to vertical storage by arranging storage niches in multiple levels connected by inclined platforms. This dimensional change allows significantly more tires to be stored in the same footprint area, increasing storage capacity without proportionally increasing the floor area required.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The storage system is divided into multiple independent storage niches arranged vertically, with each niche capable of holding a specific number of tires. This segmentation allows for better organization, easier access to individual tire batches, and improved FIFO control while maximizing space utilization.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If forklifts are used for handling, then tire movement is enabled, but ergonomic risks and accident potential increase

Engineering Contradiction:
Improvetire handlingVSAvoidergonomic risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The inclined platforms are designed to utilize gravity to automatically move tires from the upper levels down to the lower levels and exit point. This self-service mechanism eliminates the need for forklifts and manual lifting operations, thereby reducing ergonomic risks and accident potential while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical forklift system with a gravity-based passive transport system. The inclined platforms create a gravity-driven flow path that automatically moves tires without requiring external mechanical assistance, thus eliminating the hazards associated with forklift operation and improving workplace safety.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If static storage is used, then tires remain stationary, but deformation occurs

Engineering Contradiction:
Improvetire positionVSAvoidtire deformation
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The patent introduces dynamic movement to the storage system through inclined platforms that cause tires to roll and shift position continuously. This dynamic characteristic prevents tires from remaining stationary and deformed, while the controlled gravity-based movement maintains tire integrity and shape.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The inclined platforms create a continuous gravity-driven movement path that keeps tires in constant motion as they are stored and retrieved. This continuous action prevents the static deformation that would occur with stationary storage, while the systematic flow ensures tires are always in the correct position for next operations.

Inventive Principle:
Principle #20Continuity of useful action

4Quantity of substance

If vertical silos with damping devices are used, then tire storage is enabled, but FIFO control is impossible

Engineering Contradiction:
Improvetire storageVSAvoidFIFO control
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The system is designed with inclined platforms that automatically advance tires toward the exit point in a predetermined sequence. This preliminary arrangement ensures that the first tire to enter the storage system is the first to exit, providing inherent FIFO control without requiring additional active management or complex control mechanisms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of having tires stationary in vertical silos where exit order is unpredictable, the patent inverts the approach by using inclined platforms that actively push tires toward the exit. This inversion of the static storage concept naturally establishes FIFO sequencing, as tires are continuously moved forward in the direction of exit rather than remaining fixed in position.

Inventive Principle:
Principle #13The other way round (Inversion)
