Multi-positional Combination Instrument with Dual-sided Graduated Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination instruments require repositioning when used on opposing surfaces of objects, such as HVAC ducts, which complicates measurements and markings.
Innovation Solution
A multi-positional combination instrument with a graduated member and positioning arm, allowing axial and angular positioning without repositioning, featuring multiple working faces and continuous surfaces for guiding tools, enabling use on multiple surfaces without reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a combination instrument has markings on a single side, then the device complexity is reduced, but the ease of operation deteriorates when measuring opposing surfaces
Solution Approach 1:
The combination instrument is divided into two distinct sides: a first side with markings for measuring one orientation, and a second side with markings for measuring the opposing orientation. This segmentation allows each side to be optimized for specific measurement tasks, eliminating the need to reposition the instrument when measuring opposing surfaces of objects like HVAC ducts.
2Productivity
If the instrument requires repositioning for opposing surfaces, then the device complexity remains low, but the productivity decreases
Solution Approach 1:
The combination instrument is designed with multi-functionality by incorporating markings on both sides of the device. The first side enables measurement of distances, angles, and slopes in one orientation, while the second side provides the same measurement capabilities for opposing surfaces. This universal design allows the single instrument to handle multiple measurement scenarios without requiring repositioning or additional tools.
3Adaptability or versatility
If markings are placed on both sides of the instrument, then the adaptability improves for multiple surfaces, but the ease of manufacture deteriorates
Solution Approach 1:
The manufacturing process is simplified by segmenting the marking application into two separate sides. Each side can be marked independently using standard marking techniques, allowing for precise placement of measurements, angles, and slopes specific to each orientation. This segmented approach to manufacturing actually makes the process more manageable compared to attempting to create a single-sided instrument that must serve dual purposes.
