Solution Overview

Problem

Existing tool cases lack a comprehensive and efficient system for storing and organizing interchangeable driver bits for power tools and hand tools, leading to disorganization and difficulty in accessing the required bits during use.

Innovation Solution

A multi-function tool case with a housing body, extension member, and cover assembly that includes a socket and aperture system for securely holding and easily accessing tool bit holders, allowing for the storage and retrieval of bits through a rotatable lid mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional tool case is used, then the structure is simple, but the organization and accessibility of driver bits is poor

Engineering Contradiction:
ImproveAccessibility of driver bitsVSAvoidStructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The tool case is divided into multiple compartments including a first compartment for storing driver bits and a second compartment for storing corresponding information. This segmentation allows organized storage and easy retrieval of specific bits without disrupting the entire structure, improving accessibility while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tool case incorporates multiple functions within a single device: storage of driver bits, storage of corresponding information (such as codes or identifiers), and organizational categorization. This multi-functionality improves operational ease by consolidating multiple tool management tasks into one system without requiring separate storage solutions.

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

2Productivity

If driver bits are stored without organization, then the structure is simple, but the time to locate required bits increases

Engineering Contradiction:
ImproveEfficiency of tool operationsVSAvoidTime to access bits
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Driver bits are pre-organized in specific compartments based on their type, size, or usage frequency, and corresponding information is stored alongside them. This preliminary organization eliminates the need to search through the entire case when a specific bit is needed, reducing access time and improving operational efficiency without adding complex retrieval mechanisms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an information storage component that acts as an intermediary between the physical driver bits and the user. This intermediary contains identifying information (such as codes, labels, or digital data) that helps users quickly locate and identify the correct bit without physically examining each one, thereby reducing search time and improving productivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A multi-function tool case includes a housing body having a wall extending from a first end to a second end. The wall includes an exterior surface and an interior surface. A cavity is defined by the interior surface and extends from the first end toward the second end. An extension member extends from the exterior surface adjacent the second end and defines a socket oriented along a tool axis for receiving a first portion of an accessory for retaining a tool bit. A cover assembly is coupled to the first end. The cover assembly includes a cap portion and a first lid member rotatably coupled to the cap portion. The cap portion and the lid member are configured to substantially enclose the cavity.
