Flexible Storage Cover for Pencil Sharpener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pencil sharpeners with hard plastic storage hoods are uncomfortable to touch and require specific storage space matching, making them inconvenient for storage.
Innovation Solution
A pencil sharpener with a flexible storage cover that includes a base with a blade for sharpening, a flexible storage portion that can be assembled or disassembled, and features like hot melting material, sewing, internal and external threads, and buckle structures for easy attachment and detachment, allowing the storage cover to adapt to various storage spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hard plastic storage hood is used, then the storage structure is rigid and stable, but the hand feeling is hard and uncomfortable, and specific storage space requirements are needed
Solution Approach 1:
The patent replaces the hard plastic storage hood with a flexible fabric storage cover. The fabric material provides a soft, comfortable hand feeling while maintaining the storage function. The flexible nature of the fabric allows it to adapt to different storage spaces without requiring specific shape matching, thus resolving the contradiction between structural stability and comfort.
2Shape
If a hard plastic storage hood is used, then the storage structure maintains its shape, but it requires enough space matched with the shape of the hood for storage
Solution Approach 1:
The flexible fabric storage cover can be compressed and deformed to fit into various storage spaces such as bags, pockets, or drawers. Unlike the rigid plastic hood that requires dedicated space, the fabric cover adapts its shape to available storage areas, significantly improving portability and storage versatility.
3Ease of operation
If the storage cover is made of flexible material, then the hand feeling is soft and comfortable, but the attachment and detachment mechanisms become more complex
Solution Approach 1:
The attachment mechanism is divided into separate components: a fastening structure with buckles or snap buttons on the storage cover, and corresponding attachment points on the sharpener body. This segmentation allows for easy attachment and detachment while maintaining a relatively simple overall design. The modular approach prevents excessive complexity despite the flexible material requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The flexible storage cover provides a soft touch and can easily fit into different storage spaces, making the pencil sharpener comfortable to handle and convenient to store.
Implementation Method 1
a layer of hot melting material is disposed on a hood opening portion of the flexible storage cover, and the flexible storage cover and the fixing portion are fixed together by hot melting technology
