Portable Scale Stand Assembly With Articulating Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scale stand assemblies for overhead weighing lack the ability to adjust height and move around different positions efficiently, making it difficult to weigh structures and items at various locations without repositioning the items themselves.
Innovation Solution
A portable scale stand assembly comprising a base, an articulating arm assembly with a locking member and biasing member, and a scale platform, which allows for adjustable height positioning and movement via wheels, enabling the scale to be easily repositioned for weighing at different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the scale is fixed at a single height position, then the structure is simple and stable, but the scale cannot be adjusted to different heights for overhead weighing at various positions
Solution Approach 1:
The stand structure transitions from a fixed configuration to a dynamic, adjustable configuration through the articulating arm assembly. The arm can be positioned at multiple heights and locked into place, allowing the scale to adapt to different overhead weighing positions while maintaining structural stability when locked.
Solution Approach 2:
The stand is divided into separate components including a base, an articulating arm assembly with multiple segments, and a scale platform. This segmentation allows each component to be independently adjusted and positioned, enabling height variation without requiring complete structural redesign.
2Adaptability or versatility
If the scale stand is made stationary, then the structure is stable, but the scale cannot be moved around to different locations within a workspace
Solution Approach 1:
The stand incorporates wheels on the base, transforming it from a completely stationary structure to a mobile one. The wheels enable the entire stand assembly to be relocated to different work areas, while the locking mechanisms ensure stability when the stand is positioned for use.
3Adaptability or versatility
If the articulating arm allows continuous movement, then the scale can reach any position, but it becomes difficult to maintain a stable positioning during weighing
Solution Approach 1:
The locking members are positioned to engage with the articulating arm at predetermined positions along its length. Before weighing begins, the user selects and locks the appropriate height position, preparing the system for stable operation. This preliminary locking action ensures the arm remains fixed during the weighing process.
Solution Approach 2:
The biasing member automatically applies force to maintain the articulating arm in its selected position once locked. The spring-loaded mechanism provides continuous self-correcting force that counteracts external disturbances, ensuring the position is maintained without requiring active control during weighing.

Function Achieved in This Case
Enables flexible and efficient overhead weighing by allowing the scale to be positioned at various heights and moved around, facilitating the weighing of structures and items at different locations without the need to reposition the items, thereby improving usability and convenience.
Implementation Method 1
The biasing member is coupled at a first end to the upper component and at a second end to the lower component
