Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If straight rulers are used for measuring and cutting flooring materials and tiles, then the device structure is simple, but the measurement precision and contouring accuracy are insufficient for non-rectangular or complex structures
Solution Approach 1:
The ruler is divided into a main ruler body and multiple telescopic ruler bodies that can be independently adjusted. Each telescopic ruler body includes sliding members with locking mechanisms, allowing the overall ruler to be segmented into adjustable segments that can adapt to complex contours while maintaining measurement precision.
Solution Approach 2:
The ruler incorporates telescopic and sliding mechanisms that enable dynamic adjustment of the ruler's length and angle. The sliding members can move along the main ruler body and be locked at various positions, transforming a static straight ruler into a dynamic, adaptable measuring tool for complex geometries.
2Adaptability or versatility
If a fixed-length ruler is used, then the device structure is simple, but the adaptability to various staircases and complex structures is limited
Solution Approach 1:
The ruler features telescopic ruler bodies with sliding members that can be extended or retracted to different lengths. This dynamic configuration allows the same ruler to adapt to various staircase dimensions and complex structures without requiring multiple fixed-length rulers.
Solution Approach 2:
The ruler is designed as a universal measuring tool that can handle rectangular staircases, non-rectangular structures, and complex geometries. The combination of telescopic sections, sliding members, and adjustable angles enables a single ruler to perform multiple measurement functions across different application scenarios.
3Area of stationary object
If the ruler length is extended to cover larger measurement areas, then the measurement coverage is improved, but the ease of carrying and storage deteriorates
Solution Approach 1:
The ruler is segmented into a main ruler body and multiple telescopic ruler bodies connected by hinge joints. This segmentation allows the ruler to be disassembled or folded into a compact form for easy carrying and storage, while still providing extended measurement coverage when deployed.
Solution Approach 2:
The telescopic ruler bodies can be retracted into the main ruler body or nested together when not in use, creating a compact storage configuration. The sliding members can be positioned within the ruler structure, allowing the entire ruler to be collapsed to a minimal size for portability while maintaining full measurement capability when extended.

AI summary
Disclosed is a stair tread template ruler, including a main ruler body, and two side ruler bodies. Either of the side ruler bodies is provided with a sliding member that can slide in a reciprocating manner, and the main ruler body is hingedly connected to the sliding members. The two side ruler bodies are arranged at both ends of the main ruler body, and the main ruler body and the two side ruler bodies cooperate to contour a space such as a staircase. The two side ruler bodies are connected to the main ruler body, the sliding members can slide to meet various use requirements, and the main ruler body is rotatably connected to the sliding members, which facilitates adjustment of a relative angle, meets user needs, and simplifies folding and storage. The main ruler body has a multi-segment structure, and each segment is slidably connected to another.
