Solution Overview

Problem

Conventional rolling cages for soil preparation are notorious for picking up objects like rocks without an effective way to remove them, leading to potential damage and reduced durability during high-speed operations.

Innovation Solution

A rolling cage design featuring removable sections between structural members, allowing easy access and removal of trapped objects using basic hand tools, maintaining durability and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the rolling cage is fully welded for durability, then the structural strength and reliability are improved, but the ease of repair and object removal deteriorates

Engineering Contradiction:
ImprovedurabilityVSAvoidobject removal
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The rolling cage is divided into modular sections with at least one structural member containing a removable section. This segmentation allows the cage to maintain overall structural integrity while enabling easy access to the interior for object removal. The removable section can be detached using basic hand tools, providing maintenance access without compromising the welded structure's durability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A removable section is extracted from at least one structural member of the rolling cage. This extracted portion serves as an access point that can be removed and reattached, allowing objects trapped inside the cage to be retrieved while maintaining the cage's overall welded construction and durability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the rolling cage operates at high speed, then the productivity is improved, but the harmful factors from trapped objects worsen

Engineering Contradiction:
Improvehigh-speed operationVSAvoiddamage from trapped objects
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The removable section is designed to enable quick access to the cage interior before damage occurs. During high-speed operation, if objects become trapped, the removable section can be quickly detached and reattached to allow for rapid object removal, preventing potential damage while maintaining productivity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The rolling cage design allows operators to perform maintenance and object removal themselves using basic hand tools. The removable section is designed for easy detachment and reattachment, enabling field operators to clear trapped objects without specialized equipment or extensive disassembly, thus maintaining high-speed productivity while preventing damage.

Inventive Principle:
Principle #25Self-service
