Portable Fitting Assembly with Ergonomic Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitting assemblies used in demanding environments, such as construction sites and maritime industries, are large, heavy, and difficult to handle due to their robust design, making them cumbersome to maneuver in confined spaces without supporting equipment.
Innovation Solution
A portable fitting assembly with standards that have handles positioned transverse to the center axis, allowing ergonomic lifting and balancing, and featuring stackable feet and heads for stable stacking, along with a lid for protection and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the fitting is designed to be robust for demanding environments, then the strength and durability are improved, but the weight and size increase making it difficult to handle
Solution Approach 1:
The fitting assembly is divided into separate components: the fitting body, standards, conduits, and handles. This segmentation allows the heavy fitting body to be separated from the handling mechanisms, enabling robust design of the fitting while maintaining portability through detachable handles and modular standards.
2Strength
If the fitting is designed to be robust for demanding environments, then the strength and durability are improved, but the ease of operation deteriorates due to difficult handling
Solution Approach 1:
Handles are introduced as intermediary elements that mediate between the user and the heavy fitting body. These handles provide leverage and ergonomic gripping points, making it easier to move and position the robust fitting assembly without requiring direct handling of the heavy fitting body itself.
Solution Approach 2:
The assembly incorporates movable and adjustable components including detachable handles, extendable standards, and flexible conduits. These dynamic elements allow the rigid fitting body to be maneuvered more easily by distributing weight and adjusting configuration during handling and installation.
3Quantity of substance
If the fitting is made large to handle large flows, then the flow capacity is improved, but the ease of operation worsens due to difficulty in maneuvering in confined spaces
Solution Approach 1:
The large-volume fitting is segmented into a stationary fitting body and separate movable components (standards, conduits, handles). This allows the flow capacity of the fitting body to be maintained while the separate components can be maneuvered independently into confined spaces and assembled on-site.
Solution Approach 2:
The design allows components to be nested or collapsed during transport and expanded at the installation site. Conduits can be coiled or nested within standards, and handles can be detached, enabling the large-capacity fitting to be moved through tight spaces and then assembled to its full operational size.
