Solution Overview

Problem

Hair clippers with fixed attachment combs limit the range of hair lengths that can be trimmed, and traditional multi-group comb systems are inconvenient for storage and use.

Innovation Solution

An adjustable attachment comb structure for hair clippers, featuring a movable assembly with a sliding slot member and metal elastic piece, allowing for adjustable hair length trimming and secure storage, with an auditory feedback mechanism for user guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional multi-group attachment combs are used to trim different hair lengths, then the range of trimmable hair lengths is extended, but the storage and portability become inconvenient

Engineering Contradiction:
Improverange of trimmable hair lengthsVSAvoidstorage convenience
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment comb is designed with multiple comb elements that can be positioned at different locations along the comb body, allowing a single comb to perform multiple functions of trimming different hair lengths. The comb elements can be adjusted to various positions including extended, retracted, and intermediate positions, enabling one comb to replace multiple traditional combs with different fixed dimensions.

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

Solution Approach 2:

The comb elements are made movable rather than fixed, allowing dynamic adjustment of the comb structure. The comb elements can slide along the comb body and be locked at different positions, providing adaptability for different hair length requirements while maintaining a compact form factor for portable storage.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the attachment comb is made movable for adjustment, then the ease of operation is improved, but the reliability and stability may deteriorate

Engineering Contradiction:
ImproveadjustabilityVSAvoidstability during use
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The comb elements are pre-configured with specific stopping positions along the comb body, allowing users to quickly select and lock into predetermined positions without complex adjustment procedures. The stopping positions are designed to automatically engage with corresponding features on the comb body, ensuring reliable positioning before use.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A movable assembly including a sliding slot member and sliding assembly acts as an intermediary mechanism between the comb elements and the comb body. This intermediary structure guides the movement of comb elements, ensures precise positioning, and provides stable engagement during the trimming operation, thereby maintaining reliability while enabling adjustability.

Inventive Principle:
Principle #24Intermediary (Mediator)
