Chalk Holder With Arch Housing And Rake Slot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Children face difficulties in drawing evenly spaced lines and applying uniform pressure while using chalk, often resulting in messes and uneven lines, as existing chalk holders do not provide the necessary configuration for these tasks.
Innovation Solution
A chalk holder with an arch-shaped housing featuring a channel for frictional engagement of chalk, a longitudinal slit for accommodating varying chalk sizes, and a slot for converting a rake into a drawing device, along with molded indicia for personalization, is designed to facilitate even line drawing and reduce mess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If children use chalk directly without a holder, then they can draw freely, but they cannot draw evenly spaced lines and cannot apply uniform pressure
Solution Approach 1:
The patent introduces a chalk holder as an intermediary device between the child and the chalk. The holder includes a channel that receives the chalk and positioning features (such as spaced apertures or guides) that ensure the chalk is held at consistent intervals, enabling evenly spaced lines to be drawn while maintaining ease of operation through the simple holder design
2Object-affected harmful factors
If children use chalk directly without a holder, then they can draw freely, but they get chalk all over their hands and clothes
Solution Approach 1:
The chalk holder serves as a mediator that contains the chalk during the drawing process. The holder's structure (channel with opening) allows chalk to be held securely while only the necessary portion extends for marking, significantly reducing chalk transfer to hands and clothes while preserving drawing convenience
3Adaptability or versatility
If a fixed-size chalk holder is used, then it provides stable handling, but it cannot accommodate chalk pieces of varying sizes
Solution Approach 1:
The patent employs a dynamic channel design where the channel dimensions or configuration can adapt to different chalk sizes. This may include a channel with adjustable walls, a flexible receiving structure, or a design where the chalk fits snugly regardless of size variations, maintaining handling stability while accommodating varying chalk dimensions

AI summary
A chalk holder for children's games. To be used in combination with the tine portions of garden rakes to apply uniform pressure and to create evenly spaced lines when drawing on sidewalks, pavements, or other surfaces. Evenly spaced lines to be used to define the borders for games like hop scotch or to define lanes for foot races.
