Erasable-Marking Level for Accurate Single-User Hanging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools and methods for hanging objects are inefficient, inaccurate, and often require multiple users, leading to unleveled objects and reliance on memory and a steady hand for precise marking.
Innovation Solution
A level with a flat surface, leveling device, multiple edges, slits, and a writing surface that allows for precise marking and erasing, enabling single-user operation and improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional levels are used for hanging objects, then the basic leveling function is provided, but the tools are cumbersome and require multiple users or additional tools to operate accurately
Solution Approach 1:
The patent combines multiple functions into a single level device: the leveling function, the marking function (via integrated marking surfaces), and the measurement function are all integrated into one tool. This eliminates the need for separate marking tools and reduces the requirement for multiple users, as the single device provides all necessary capabilities for accurate object hanging.
Solution Approach 2:
The level device is designed with multi-functionality to serve various purposes: it can level objects, mark positions for hanging, and provide measurement references. The inclusion of marking surfaces and measurement indicators within the same device makes it a universal tool that replaces multiple separate tools, thereby improving ease of operation and reducing device complexity.
2Measurement precision
If users rely on memory and a steady hand to make marks for nail holes, then no additional tools are needed, but accuracy is compromised and errors occur
Solution Approach 1:
The patent introduces marking surfaces as an intermediary between the level device and the final marking action. These dedicated marking surfaces provide a stable, precise reference that mediates the transition from measurement to marking, ensuring accuracy is maintained without requiring the user to rely solely on memory and hand steadiness.
Solution Approach 2:
The level device performs the marking function itself through integrated marking surfaces, eliminating the need for separate marking actions or tools. The device serves its own marking needs by providing dedicated surfaces that automatically align with the leveling function, thereby improving marking accuracy without adding external complexity.
3Ease of manufacture
If traditional marking methods are used without slits or writing surfaces, then the tool structure remains simple, but the opportunity for error increases and marks cannot be easily made or erased
Solution Approach 1:
The patent segments the marking function from the main level structure by incorporating separate marking surfaces and slits. This segmentation allows the marking mechanism to be optimized independently for ease of use and reliability, while the main level structure remains relatively simple. The slits and marking surfaces are distinct components that can be manufactured and assembled separately.
Solution Approach 2:
The patent incorporates erasable marking surfaces that allow marks to be made and then erased for reuse. This enables the marking surfaces to be discarded (erased) and recovered (reused) multiple times, improving reliability by eliminating permanent errors and enhancing ease of manufacture through the ability to correct and redo marks without replacing the entire device.

AI summary
A level for hanging objects designed to receive one or more marks from a writing utensil. The level includes a plurality of edges, a leveling component, a slit, and a writing surface. The leveling component indicates an orientation of the level (e.g., horizontal, vertical). The writing surface receives marks from the writing utensil and is designed for the received marks to be removed (e.g., erasure).
