Triangular Tailor's Chalk Case with Rotatable Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tailor's chalk is brittle and difficult to manage in cluttered workspace environments, requiring a protective case that also serves as a work stand for easy accessibility and sharpening.
Innovation Solution
A protective case with a rotatable lid that functions as both a storage container and a work stand for tailor's chalk, featuring a triangular base with a retaining pocket and offset hinge elements, allowing the lid to rotate 180° for access and beyond 270° for an erect position, along with a roughened surface for sharpening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If tailor's chalk is stored in boxes with multiple pieces, then storage capacity is improved, but accessibility and protection of individual pieces deteriorates
Solution Approach 1:
The invention divides the storage system into individual compartments, each designed to hold a single piece of tailor's chalk. This segmentation allows each chalk piece to be independently accessed and protected, resolving the contradiction between storing multiple pieces and maintaining easy accessibility to individual items.
2Ease of operation
If tailor's chalk is kept in cluttered workspace environments, then accessibility is improved, but protection and organization deteriorates
Solution Approach 1:
The invention merges the storage case with a work stand function into a single integrated device. The case can be positioned upright on the workspace, combining protection during storage with accessibility during use, thereby eliminating the need to place chalk directly in cluttered areas while maintaining ease of access.
3Object-affected harmful factors
If a protective case is designed for individual chalk pieces, then protection is improved, but multi-functionality deteriorates
Solution Approach 1:
The invention designs the protective case to serve multiple functions: it acts as a protective storage container when closed, and as an upright work stand when opened. The rotatable lid mechanism enables the case to position itself in various orientations, providing both protection during transport/storage and accessibility during use, thus achieving multi-functionality without compromising protection.
4Adaptability or versatility
If the lid is made rotatable for work stand position, then accessibility and versatility are improved, but device complexity increases
Solution Approach 1:
The invention incorporates a rotatable lid mechanism that allows the case to dynamically change its orientation from a closed horizontal position to an open upright work stand position. This dynamic capability enables the case to adapt to different usage scenarios without requiring complex additional components, as the rotation mechanism integrates with the existing hinge structure.

AI summary
A case for tailor's chalk includes: (a) a generally triangular base with a central portion, a retaining pocket along one edge thereof, said pocket opening toward the center of said triangular base and a pair of offset base hinge elements adjacent the pocket located adjacent opposed ends of said pocket along said one edge of said base; and (b) a generally triangular lid shaped and adapted to mate with the base and hinged thereto by a pair of mating offset lid hinge elements located along one edge of said generally triangular lid, said lid hinge elements being snap-fit mateable with said base hinge elements, the offset between said generally triangular base and said generally triangular lid being sufficient to define a storage cavity for the chalk in a closed position, the lid having a central portion opposing the central portion of the base in said closed position, the lid being coupled to the base so as to be rotatable with respect thereto to an open position where the lid is rotated by 180° with respect to the closed position and the chalk is accessible and wherein further the lid is rotatable with respect to the base to a work stand position where the lid is rotated by more than 270° with respect to the closed position such that the base is in an erect open position leaning at least slightly rearwardly where the chalk is accessible to a user.
