Solution Overview

Problem

Conventional hair clips have a fixed hair-clamping range, making them unsuitable for varying hair amounts, and existing adjustable designs often experience disengagement or unstable positioning under force.

Innovation Solution

A hair clip design featuring symmetric clip pieces with elastic elements and rectilinear connecting plates with positioning grooves and pegs, allowing for adjustable clamping range while maintaining stable engagement through slits and protrusions for flexible deformation and secure coupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hair clip is designed with fixed clamping members, then the structure is simple and easy to manufacture, but the hair-clamping range cannot be adjusted for different hair amounts

Engineering Contradiction:

Improvehair-clamping range adjustmentVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connecting plates are divided into multiple segments with positioning grooves and pegs, allowing the hair clip to be segmented into different clamping configurations. This enables adjustment of the hair-clamping range while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hair clip transitions from a fixed structure to a dynamically adjustable one through the positioning grooves and pegs mechanism. The connecting plates can pivot and lock at different positions, providing adaptability for different hair amounts while keeping the design simple.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the connecting members use holes and pins without angle limitation, then the structure is simple, but the pins may slide along the holes causing disengagement under excessive force

Engineering Contradiction:

Improveengagement stabilityVSAvoidpositioning mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The positioning grooves and pegs are designed to prevent disengagement before it can occur. The angle limitation built into the positioning mechanism counteracts the sliding tendency of pins in holes, providing reliable engagement stability without requiring complex additional components.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The positioning grooves act as an intermediary mechanism between the connecting plates and pins. They mediate the connection by providing guided paths that allow movement within safe angles while preventing excessive sliding that would cause disengagement.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the connecting members and plates are adjusted to different positions, then the hair-clamping range is extended, but the coupling and positioning may not be secure causing width changes

Engineering Contradiction:

Improveclamping width adjustmentVSAvoidpositioning stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The positioning grooves and pegs are pre-configured at specific locations on the connecting plates. This preliminary arrangement ensures that when the plates are adjusted to different positions, they automatically lock into secure coupling points, maintaining positioning stability throughout the adjustment range.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Different regions of the connecting plates have different positioning grooves and pegs arranged at specific locations. This local differentiation provides secure coupling at each adjustment position, ensuring that the clamping width remains stable once adjusted, while still allowing versatility in the range of adjustment.

Inventive Principle:

Principle #3Local quality
