Solution Overview

Problem

Existing tool storage units lack efficient and versatile mechanisms for securely stacking and transporting tools, particularly in environments where stability and ease of use are crucial.

Innovation Solution

The development of a container assembly with various coupling mechanisms, including latches, couplers, and retractable cleats, that allow for secure stacking and easy decoupling of tool storage units, utilizing features like rib walls, threaded components, and spring-loaded rails for enhanced stability and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If multiple coupling mechanisms (latches, couplers, rib walls) are implemented for secure stacking, then the stability and security of tool storage units is improved, but the device complexity increases

Engineering Contradiction:
Improvestacking stabilityVSAvoidcoupling mechanism complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The coupling mechanism is divided into separate functional components: latches for primary engagement, couplers for secondary engagement, and rib walls for structural support. This segmentation allows each component to perform its specific function independently, achieving stable stacking without requiring a monolithic complex structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling mechanisms are designed to serve multiple functions: latches provide both security and alignment, couplers enable both stacking and transport configurations, and rib walls provide both structural support and engagement surfaces. This multi-functionality reduces the need for separate dedicated components for each function.

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

2Reliability

If secure engagement mechanisms are used to ensure stable stacking, then the reliability of tool storage units is improved, but the ease of operation for assembly and disassembly deteriorates

Engineering Contradiction:
Improveengagement securityVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The latches and couplers are pre-configured in specific positions and orientations that automatically engage with corresponding receptacles when containers are stacked. This preliminary positioning eliminates the need for manual alignment or complex assembly procedures while maintaining secure engagement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The coupling mechanisms incorporate movable components that transition between engaged and disengaged states through simple user actions. The latches can be easily actuated to lock or unlock, and the couplers can be released with minimal effort, providing both security during stacking and ease of operation when needed.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple coupling walls and couplers are used to accommodate various tool sizes and shapes, then the adaptability of the storage system is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvetool size accommodationVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The coupling walls and couplers are designed as universal components that can accommodate various tool sizes and shapes through a standardized interface. The same coupling mechanism works for different container configurations, eliminating the need to manufacture specialized components for each tool type while maintaining adaptability.

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

Solution Approach 2:

The coupling mechanisms use homogeneous design principles with standardized dimensions, materials, and geometries across all components. This uniformity simplifies manufacturing processes and quality control while providing consistent performance across the entire storage system, accommodating various tools through standardized rather than customized solutions.

Inventive Principle:
Principle #33Homogeneity

AI summary

Described herein are various coupling systems to be used with storage units that are selectively coupled and decoupled. The coupling systems may be used with storage units that are stackable and/or transportable, thus allowing the storage units to function well within a large stationary environment, such as a basement, and also for a subset of the storage units to be selected and easily moved to another location.
