Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic clippers with guide combs face issues due to a weakened attachment mechanism, leading to comb displacement during use, resulting in unwanted haircuts, especially problematic for professionals who require precision and speed.

Innovation Solution

A guide comb with a holdable extension that includes a central portion with teeth and an attachment member, featuring an open-style or closed-style holdable extension to securely attach to the clipper, providing additional grip and stability through ergonomic design and attachment to the clipper body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the attachment mechanism is used to secure the guide comb to the clipper, then the guide comb can be held in place during use, but the attachment mechanism becomes weak after frequent use leading to comb displacement

Engineering Contradiction:

Improveattachment mechanism reliabilityVSAvoidattachment mechanism durability

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent introduces a holdable extension as an intermediary element that provides an additional interface between the user's finger and the guide comb. This extension acts as a mediator that allows the user to apply direct manual pressure to secure the comb against the clipper head, supplementing the weakened attachment mechanism and preventing displacement during use.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the guide comb is secured firmly to the clipper, then comb displacement is prevented, but the user cannot easily remove or change the guide comb

Engineering Contradiction:

Improveguide comb securityVSAvoidguide comb removal ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The holdable extension enables dynamic control of the guide comb's attachment state. By allowing the user to apply varying degrees of manual pressure through the extension, the comb can be firmly held during cutting operations and easily released when needed, providing adaptable security that responds to the user's operational needs.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the attachment mechanism is simplified for easy use, then ease of operation is improved, but the attachment strength decreases leading to comb displacement

Engineering Contradiction:

Improveattachment easeVSAvoidattachment strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The patent merges two attachment approaches: the simplified attachment mechanism for easy initial attachment and the holdable extension for enhanced security during use. This combination allows the system to benefit from both the ease of operation provided by the simple attachment mechanism and the attachment strength provided by the user's finger pressure through the extension.

Inventive Principle:

Principle #5Merging (Combining)
