Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional horizontal rulers are cumbersome due to their length and require manual handling, leading to user fatigue during extended use, as they can only be folded once and lack efficient storage and carrying solutions.
Innovation Solution
A foldable horizontal ruler design featuring multiple interconnected units with a rotating kit, magnetic adsorption, and a hook mechanism for easy storage and reduced user effort, incorporating a U-shaped connecting end, rotating shaft, and arc edges to prevent collision and enhance firmness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the horizontal ruler is made longer to improve measurement range, then the measurement capability is improved, but the convenience of storage and carrying deteriorates
Solution Approach 1:
The ruler body is divided into multiple ruler units (first ruler unit, second ruler unit, third ruler unit) that can be folded relative to each other through connecting ends and connecting blocks. This segmentation allows the long ruler to be folded into a compact form for storage and carrying, while maintaining the full length when extended for measurement.
2Length of moving object
If the horizontal ruler is made longer to improve measurement range, then the measurement capability is improved, but the ease of carrying deteriorates
Solution Approach 1:
The ruler is segmented into multiple lightweight units connected by rotating mechanisms. Each unit can be independently handled and folded, reducing the effective weight that needs to be carried at any one time while maintaining the full measurement length when extended.
3Ease of operation
If manual handling is used to operate the horizontal ruler, then the operational simplicity is improved, but the user fatigue level increases during extended use
Solution Approach 1:
Magnetic blocks are integrated into the ruler units to provide magnetic adsorption capability. When measuring metal surfaces, the magnetic blocks automatically adsorb to the workpiece, eliminating the need for continuous manual holding and significantly reducing user fatigue during extended measurement tasks.
4Volume of moving object
If the ruler units are folded to improve storage convenience, then the storage compactness is improved, but the structural complexity increases
Solution Approach 1:
The folding mechanism is achieved through simple connecting ends and connecting blocks with rotating kits, creating a modular segmented structure that folds compactly without requiring complex mechanisms.
Solution Approach 2:
When folded, the ruler units nest within each other in a compact configuration, with each unit containing or overlapping the previous one, achieving maximum compactness for storage while using simple rotational joints rather than complex folding mechanisms.

AI summary
A foldable horizontal ruler, comprising a ruler body having at least two or more ruler units, wherein a connecting end is arranged on the ruler unit, a connecting block is arranged between the ruler units, and the connecting end forms a rotating kit with the connecting block so that the adjacent ruler units can be folded. The connecting end, arranged on the ruler unit, is provided with a connecting block, and the adjacent ruler units can be folded through the connecting block. The ruler body can be folded in multiple segments by designing more than one set of ruler body units, which makes the storage or carrying become more convenient. The magnet is arranged on the rotating shaft and the fixed pin, and the end of the ruler unit exposed. The magnet forms adsorption with the measured object, which reduces long-time lifting and reduces the user's level of fatigue.
