Solution Overview

Problem

Existing tool containers lack modular components that allow for user customization and efficient storage of tools in various positions, and often fail to provide secure closure mechanisms to prevent tools from falling out during transport.

Innovation Solution

A container with modular components, including a base and a lid hinged together, featuring recesses and pegs that allow tools to be stored in multiple orientations, and a locking mechanism to secure the lid in closed and open positions, ensuring tools remain in place during transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If tools are stored in a traditional fixed container, then the structure is simple, but the tools cannot be positioned flexibly or customized by users

Engineering Contradiction:
Improvetool positioning flexibilityVSAvoidcontainer structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container is divided into modular components: a base with multiple recesses, a lid with corresponding pegs, and interchangeable tool holders. Each component can be independently positioned or reconfigured, allowing flexible tool placement while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The recesses and pegs are designed as universal interfaces that can accommodate various tool types and configurations. The same base structure can hold different tools in different orientations, and the lid can secure multiple tools simultaneously, providing multi-functional capability without proportionally increasing complexity.

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

2Ease of operation

If the lid is made movable to allow access, then user access is improved, but tools may fall out during transport

Engineering Contradiction:
Improvelid accessibilityVSAvoidtool retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The pegs are pre-positioned on the lid to align with recesses in the base. When the lid is closed, the pegs automatically engage with the recesses to secure tools before transport begins, preventing tools from falling out during movement while allowing easy access when opened.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pegs act as intermediary elements between the lid and the tools. They provide a mechanical connection that secures tools during transport while allowing the lid to remain movable for access. The pegs transfer the securing function from a fixed structure to a movable one.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If tools are secured in fixed positions, then tools remain stable during transport, but user customization and repositioning is difficult

Engineering Contradiction:
Improvetool stabilityVSAvoidtool repositioning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The tool securing system transitions from a static fixed structure to a dynamic reconfigurable system. The pegs can be removed and repositioned to different recesses, allowing tools to be stabilized during transport while enabling easy repositioning and customization by the user when needed.

Inventive Principle:
Principle #15Dynamics

AI summary

A container includes a base, first recesses, a lid, and an insert. The base includes a lower surface. Base walls extend from the lower surface. The lower surface and the base walls define a cavity. The first recesses are positioned adjacent to the lower surface. The lid is movably coupled to the base to selectively enclose the cavity. The lid includes an upper surface and lid walls extend from the upper surface. The insert is positioned within the cavity and removably coupled to the lower surface of the base. The insert includes a projection received within one of the first recesses. The insert is engaged by the lid when the lid is closed.
