Solution Overview
Problem
Existing measurement tools often struggle to provide accurate measurements, especially in hard-to-reach areas and corners, requiring multiple tools and lacking precision, which can lead to errors in construction and maintenance work.
Innovation Solution
A measurement device with a main body, a retractable tape measure, and folding rulers that can be perpendicularly disposed to measure lengths and right-angled corners, along with a magnet connector for secure attachment, allowing for precise measurements of external surfaces and objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate measurement tools are used to measure hard-to-reach areas and corners, then measurement coverage is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple measurement tools (tape measure, folding rulers, square tool) into a single integrated device. The tape measure, first folding ruler, second folding ruler, and square tool are all attached to a common body, allowing them to function as one unified measurement system rather than separate tools.
Solution Approach 2:
The integrated measurement device performs multiple measurement functions simultaneously - linear measurements with the tape measure, angular measurements with the folding rulers, and square/rectangle measurements with the square tool - all within a single device that can access hard-to-reach areas.
2Measurement precision
If multiple separate measurement tools are used to measure hard-to-reach areas, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
By integrating multiple precision measurement tools into one device, the patent maintains measurement accuracy while simplifying operation. The user operates a single device rather than switching between multiple tools, reducing operational complexity while preserving precision capabilities.
3Ease of operation
If a compact measurement device is used for hard-to-reach areas, then ease of operation is improved, but measurement precision may deteriorate
Solution Approach 1:
The device is segmented into multiple functional components (tape measure, folding rulers, square tool) that can be independently positioned and used. This segmentation allows each component to maintain its precision capabilities while the overall compact design enables access to hard-to-reach areas.
Solution Approach 2:
The folding rulers can be extended perpendicular to the tape measure, adding a dimensional aspect to the measurement capability. This allows measurements in multiple directions from a single compact device, maintaining precision while improving accessibility.
