Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rulers are limited in their functionality, unable to perform multi-scale measurements and drawing complex shapes, are prone to damage, and are inconvenient to carry due to their bulkiness, necessitating the need for multiple rulers for different tasks.
Innovation Solution
A multifunctional rectangular ruler integrating various measurement scales (metric, imperial, pixel, pica, point) and drawing capabilities (protractor, isometric cubes, triangular grids, circular holes) with compact dimensions, allowing for quick and versatile measurements and drawings, including features like a level and portable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate rulers are used for different measurement scales and drawing functions, then measurement precision and drawing capability are improved, but device complexity and portability deteriorate
Solution Approach 1:
The patent combines multiple measurement scales (metric, imperial, pixel, pica, point) and drawing functions (protractor, isometric cubes, triangular grids, circular holes) into a single rectangular ruler body, eliminating the need to carry multiple separate rulers while maintaining all measurement and drawing capabilities
Solution Approach 2:
The ruler is designed as a universal tool that performs multiple functions: measuring in different scales, drawing straight lines, measuring angles with the protractor, drawing geometric shapes using isometric cubes and circular holes, and checking levelness with the built-in level, making it suitable for various professional and everyday tasks
2Ease of manufacture
If traditional rulers are used for measuring and drawing, then simplicity and ease of manufacture are improved, but functionality and adaptability deteriorate
Solution Approach 1:
The ruler body is segmented into distinct functional zones with different measurement scales and drawing features, each optimized for specific tasks while maintaining a unified rectangular structure that is easy to manufacture
Solution Approach 2:
Different regions of the ruler surface have different properties: metric scale marks on one side, imperial scale marks on the other, protractor arcs at corners, isometric cubes in specific areas, and circular holes at predetermined positions, allowing each local area to serve its specific function while maintaining overall simplicity
3Reliability
If bulkier rulers are used for durability and functionality, then reliability and measurement capability are improved, but portability and ease of carrying deteriorate
Solution Approach 1:
The ruler integrates multiple functional elements within its compact rectangular body, nesting protractors, isometric cubes, and circular holes within the available space to maximize functionality while maintaining a compact, portable form factor that fits in pockets or small bags
Solution Approach 2:
The ruler utilizes the two-dimensional surface area efficiently by placing different measurement scales and drawing features on opposite sides and corners of the rectangular body, maximizing functionality without increasing the overall footprint or bulk
