Crayon Holder With Spring-Loaded Clothespin Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crayons are prone to breaking due to their soft and fragile nature, making them difficult to handle and use, especially when used as stubs, as they can be hard to hold and may break again.
Innovation Solution
A crayon holder device with a cylindrical body and a spring-loaded clothespin mechanism that provides a slip fit for crayons, along with a zip tie to secure the clothespin, and an integrated crayon sharpening apparatus, or an alternative design featuring a plunger with smoothed circular grooves and retainer elements to securely hold crayons in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If crayons are made of soft wax to enable coloring, then coloring ability is improved, but durability and resistance to breaking deteriorates
Solution Approach 1:
The crayon is divided into two functional parts: the soft wax core for coloring and the holder mechanism for structural support. The holder (cylindrical body with clothespin mechanism) provides durability while the crayon tip maintains its soft coloring properties, effectively separating the conflicting requirements of softness and strength.
Solution Approach 2:
The holder acts as an intermediary structure between the user's hand and the soft crayon. It provides a firm grip point while the crayon tip remains soft for coloring. The spring-loaded clothespin mechanism serves as a mediator that secures the crayon without requiring the crayon itself to be structurally strong.
2Ease of operation
If crayons are held loosely for easy insertion, then ease of insertion is improved, but stability during manipulation deteriorates
Solution Approach 1:
The clothespin mechanism transitions from an open state (for easy insertion) to a closed state (for secure holding). When the crayon is inserted, the spring automatically closes the clothespin jaws, dynamically adapting the holder's grip from loose to firm, thus resolving the contradiction between ease of insertion and stability during use.
Solution Approach 2:
The spring-loaded clothespin mechanism is self-actuating. As the crayon is inserted into the cylindrical body, the spring automatically engages and closes the clothespin jaws around the crayon, providing secure holding without requiring additional manual action. This self-service mechanism ensures both easy insertion and reliable stability.
3Ease of repair
If crayon stubs are used after breaking, then resource utilization is improved, but ease of handling deteriorates
Solution Approach 1:
The holder is designed to accommodate crayons of various lengths and diameters, including broken stubs. The adjustable clothespin mechanism can grip different sizes, making the device universally applicable to both full-length crayons and short stubs, thereby maintaining ease of handling for all crayon states.
Solution Approach 2:
The clothespin mechanism allows for parameter adjustment in grip force and positioning. When handling short stubs, the spring-loaded jaws can be positioned to grip the stub at its center of mass, changing the handling parameters to compensate for the reduced length and improve ease of operation for stubs.
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 crayon holder securely holds crayons and stubs in place, allowing for easier use and manipulation without breaking, while the integrated sharpener enables convenient sharpening, enhancing the drawing experience by preventing breakage and improving usability.
Implementation Method 1
the spring contacts both the portion of the clothespin and the cylindrical body, asserting pressure urging the portion of the clothespin against the exposed portion of the crayon, holding the crayon in place in the cylindrical body

AI summary
A crayon holder has a cylindrical body having a length, an outside diameter and an inside diameter, the inside diameter providing a slip fit for a crayon, and a mechanism adapted to hold a crayon, once inserted into the cylindrical body at a first end, in place in the cylindrical body while the crayon holder is manipulated in use.
