Hair Container with Attachment Comb for Hair Cutting Appliance

Solution Overview

Problem

Existing hair cutting appliances face challenges in hair collection, with cut hair sections often falling arbitrarily, adhering to clothing and skin, and obstructing visibility during styling operations, while adjustable combs complicate hair catching and require additional space.

Innovation Solution

A hair container with an attachment comb that attaches medially to the hair cutting appliance, allowing for improved hair collection without obstructing the cutting zone, and enabling easy adjustment and quick assembly/disassembly, using a snap-lock mechanism for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed hair collection container is integrated into the appliance housing, then hair collection is effective, but the appliance cannot be used for styling operations requiring visibility

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The hair collection container is segmented from the main appliance housing and integrated onto the attachment comb instead. This allows the container to be present during trimming operations while being removable or repositionable during styling operations, resolving the contradiction between reliable hair collection and styling versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment comb with integrated container is designed to be dynamically attachable and detachable from the appliance. During trimming, the comb with container is attached for effective hair collection. During styling, the comb can be detached or repositioned to maintain visibility, providing dynamic adaptability between different operational modes.

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If an adjustable spacing comb is added to set cutting length, then trimming precision is improved, but hair catching becomes more complex and requires additional space

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The hair collection container is merged with the attachment comb structure itself, rather than being a separate mechanism. The container utilizes the comb's attachment interface and housing space, eliminating the need for additional complex hair catching mechanisms while maintaining precise cutting length control through the comb's spacing features.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The attachment comb serves multiple functions: it provides precise spacing for cutting length control, acts as the mounting interface for the hair collection container, and maintains a simple structural design. This multi-functionality resolves the contradiction by achieving precise trimming without adding complex hair catching mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If a removable hair collecting tray is inserted into the cutting head assembly, then hair collection is improved, but the device requires additional assembly steps and space

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The hair collection container is merged with the attachment comb as an integrated unit, rather than being a separate tray inserted into the cutting head. This integration allows the container to be attached in the same simple manner as the comb itself, maintaining ease of operation while achieving reliable hair collection.

Inventive Principle:

Principle #5Merging (Combining)
