Solution Overview

Problem

Craftsmen, such as electricians, face challenges in conveniently carrying a variety of step bits and pilot bits for punching holes in sheet metal, as existing solutions lack a compact and efficient means for organizing and securing these tools.

Innovation Solution

A step bit pouch designed with multiple textile sheets and seams, forming a belt-attachable holster that differentiates and securely holds various step bits and a pilot bit, utilizing fasteners like magnetic or hook-and-loop systems for easy access and attachment to a belt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If craftsmen use traditional tool carrying methods, then they can carry multiple drill bits, but the tools become cumbersome and difficult to access

Engineering Contradiction:
ImproveEase of accessing drill bitsVSAvoidComplexity of tool carrying system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pouch is divided into multiple separate compartments, each designed to hold a specific drill bit size. This segmentation allows craftsmen to quickly access the needed bit without rummaging through a single large compartment, improving ease of operation while keeping each compartment simple and organized.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pouch utilizes vertical hanging space by incorporating a belt loop at the top, transitioning from horizontal tool storage to vertical suspension. This dimensional change allows the pouch to hang freely at the craftsman's side, making tools easily accessible without adding bulk to the belt or tool belt complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If craftsmen carry all drill bit sizes, then they are prepared for any task, but the carrying weight and bulk increase

Engineering Contradiction:
ImproveVersatility in drill bit sizesVSAvoidWeight of drill bit pouch
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The pouch contains multiple small, separate compartments instead of one large compartment, allowing craftsmen to carry only the specific drill bit sizes they need for particular tasks. This segmentation enables selective tool carrying, reducing overall weight while maintaining adaptability for different drilling requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each compartment is specifically sized and shaped to accommodate particular drill bit dimensions, with differentiated compartments for various bit sizes. This local quality optimization ensures that each section serves its specific purpose efficiently, allowing versatile tool organization without carrying unnecessary weight.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If drill bits are stored loosely, then they are easy to access, but they can get lost or misplaced

Engineering Contradiction:
ImproveEase of retrieving drill bitsVSAvoidSecurity of drill bit storage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Each drill bit has its own dedicated compartment with individual retention features, preventing bits from moving freely or becoming misplaced. The segmented design with defined boundaries for each bit maintains security and reliability while keeping retrieval simple through clear compartment identification.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pouch design allows drill bits to naturally settle into their correct compartments based on their size, with each compartment's dimensions guiding the bit to its proper position. This self-organizing feature ensures bits are always in their designated spots without requiring active management, maintaining both security and ease of access.

Inventive Principle:
Principle #25Self-service
