Solution Overview

Problem

Existing cages for containing inert materials lack stability during loading, unloading, and transport, and are difficult to assemble and stack for forming complex structures like retaining walls.

Innovation Solution

The cage design incorporates specific hook shapes at the ends of vertical rods for connecting to the base, including U-shaped and J-shaped hooks, which enhance stability and facilitate assembly and stacking, along with comb-like hooks for efficient transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If simple wire mesh surfaces are connected using basic welding or bending methods, then the manufacturing complexity is reduced, but the stability of the cage structure during loading, unloading, and transport deteriorates

Engineering Contradiction:
Improveconnection method complexityVSAvoidcage structure stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by implementing specialized connection elements (hooks, lugs, or folded portions) at specific locations where vertical walls meet the base, rather than using uniform connection methods throughout. These localized structural features provide enhanced stability at critical connection points while maintaining simplicity in other areas of the cage structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs curved or folded wire configurations (such as U-shaped hooks, J-shaped connectors, or folded portions) instead of straight rigid connections. These curved elements provide mechanical advantage and flexibility, allowing the connection to accommodate movement and stress while maintaining structural stability during loading and transport operations.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Ease of manufacture

If conventional connection methods are used to join vertical walls to the base, then the ease of manufacture is improved, but the ease of operation for assembly and stacking deteriorates

Engineering Contradiction:
Improvecage manufacturing easeVSAvoidassembly and stacking ease
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent divides the connection function into separate, modular elements (such as discrete hooks, lugs, or folded portions) that can be independently formed and attached to the base. This segmentation allows for simplified manufacturing of individual components while enabling easy assembly by simply engaging these pre-formed elements with corresponding features on vertical walls or stacking elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediate connection elements (hooks, lugs, or folded portions) that serve as mediators between the base and vertical walls. These intermediary features simplify the connection process by providing dedicated engagement points that facilitate both assembly operations and stacking operations without requiring complex welding or bending procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If basic wire mesh connection structures are used, then the device complexity is minimized, but the adaptability for forming complex structures like retaining walls deteriorates

Engineering Contradiction:
Improveconnection structure complexityVSAvoidstructure formation adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent designs connection elements (hooks, lugs, or folded portions) that serve multiple functions: they provide structural stability during loading and transport, enable easy assembly of individual cage units, and facilitate stacking to form complex structures such as retaining walls. This multi-functionality increases adaptability without significantly increasing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention concerns a cage for containing and carrying inert material, which comprises a base and side walls, in the form of wire meshes composed of horizontal and vertical rods in crisscrossed arrangement, wherein at least one vertical wall is connected to the base of the cage, at its bottom end, by approximately J-shaped hooks, which are designed to impart structural stability and resistance to vertical stresses caused by the weight of the material, during unloading, lading and transport of the cage.
