Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing extension poles used in electrical applications are not designed for striking or removing lag bolts, which are necessary tasks for linemen working on power lines.

Innovation Solution

A multi-use hammer and extension pole combination that includes a striking head, a claw for nail removal, a rectangular cavity for lag bolt engagement, and a ring for attaching to an extension pole, allowing the hammer to be used as a hand-held striking tool and lag bolt remover, with a mechanism for secure attachment and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If extension pole is used for electrical applications only, then electrical safety is maintained, but versatility for striking and lag bolt removal is lost

Engineering Contradiction:

ImproveversatilityVSAvoidelectrical safety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The hammer head is designed with multiple functional components (striking face, claw, rectangular cavity) that enable it to perform electrical work, striking, nail removal, and lag bolt removal tasks, allowing a single tool to replace multiple separate tools while maintaining electrical safety through the insulating extension pole

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If traditional hammer is used for striking and nail removal, then those functions are performed, but lag bolt removal capability is missing

Engineering Contradiction:

ImprovefunctionalityVSAvoidtool variety

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hammer head incorporates a rectangular cavity specifically designed to engage with square-drive lag bolts, enabling the same tool to remove both nails and lag bolts, eliminating the need for separate tools for different fastener types

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The hammer head features differently shaped components (claw for nails, rectangular cavity for lag bolts) at specific locations, allowing each component to be optimized for its specific function while being part of a single integrated tool

Inventive Principle:

Principle #3Local quality

3Strength

If extension pole is made for electrical insulation, then electrical safety is ensured, but striking capability is compromised

Engineering Contradiction:

Improvestriking capabilityVSAvoidelectrical insulation

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The tool is divided into two distinct segments: the extension pole maintains electrical insulation properties for safety, while the hammer head provides striking and removal functions, allowing each component to be optimized for its specific purpose without compromise

Inventive Principle:

Principle #1Segmentation
