Segmented Hair Roller Assembly with Nested Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair rollers occupy significant space for storage and transportation, making them impractical for salons and travelers due to their non-compact design.
Innovation Solution
The development of hair rollers that can be disassembled into flexible half-cylindrical pieces with mating devices, allowing for easy assembly and nesting, enabling compact storage and transportation while maintaining functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If hair rollers are made as complete cylindrical units, then they provide full functionality for hair curling, but they occupy significant storage space and are difficult to transport
Solution Approach 1:
The hair roller is divided into two separate half-cylindrical pieces that can be stored independently in a compact case, significantly reducing storage volume while maintaining the ability to form a complete functional roller when needed
Solution Approach 2:
The two half-cylindrical pieces are designed to nest within each other when not in use, creating an extremely compact storage configuration that minimizes the volume occupied during transport and storage
2Volume of moving object
If hair rollers are designed to be disassembled into multiple pieces, then storage space is reduced, but the device complexity increases
Solution Approach 1:
The roller is segmented into two simple half-cylindrical pieces with basic coupling features, avoiding complex mechanisms while achieving the disassembly goal
Solution Approach 2:
The two half-cylindrical pieces incorporate mating surfaces and coupling features that allow them to be easily joined together, simplifying the assembly process despite the multi-piece design
3Ease of manufacture
If hair rollers are made as complete units, then manufacturing is simple, but storage and transportation become impractical
Solution Approach 1:
The roller is manufactured as two separate half-cylindrical pieces using standard molding processes, which remains simple and cost-effective while enabling compact storage through nesting
4Adaptability or versatility
If multiple hair rollers are needed for different hair styling needs, then versatility is improved, but the amount of storage space required increases
Solution Approach 1:
Each roller size is divided into nested half-cylindrical pieces, allowing multiple different-sized rollers to be compactly stored in a single case while maintaining versatility for different hair styling needs

AI summary
Embodiments of the present invention relate to a hair roller which can be separated into a pair of half-cylindrical roller pieces, pairs of half-cylindrical roller pieces, and a method of storing half-cylindrical roller pieces by nesting the half-cylindrical roller pieces. The hair roller of the invention includes a whole cylindrical body separable along a vertical axis into half-cylindrical roller pieces which include a plurality of mating devices configured to selectably couple the half-cylindrical roller pieces to form the whole cylindrical body, wherein the half-cylindrical roller pieces are capable of being nested. The pair of half-cylindrical roller pieces of the invention are identical in shape, which include a plurality of tabs and orifices, where the tabs have protuberances which protrude into a corresponding orifice when the lateral edges of the pair of roller pieces are aligned.
