Two-Panel Seated Weight Scale for Accurate Patient Weighing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight scales are designed for standing individuals, making it difficult to obtain accurate weights for seated persons, especially in medical settings where precise weight measurements are crucial.
Innovation Solution
A two-part weight scale system comprising a first panel for weighing the upper body and a second panel for weighing the lower body, with a control assembly to calculate and display the total weight, powered by rechargeable batteries and enabling wireless or wired data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional standing weight scales are used, then the device structure is simple, but seated persons cannot be weighed accurately
Solution Approach 1:
The weight scale is divided into two separate panels: a first panel for weighing the upper body (seated on buttocks) and a second panel for weighing the lower body (feet). Each panel has its own weight sensor, and the control assembly combines these two measurements to provide the total weight, enabling accurate weighing of seated persons while maintaining manageable device complexity
Solution Approach 2:
The scale is designed to serve multiple functions: it can weigh both standing and seated persons, and can measure both upper and lower body weights separately. The two-panel design with combinable measurements provides versatility in weighing different body portions, making the device adaptable to various weighing scenarios
2Measurement precision
If specialized equipment is used to weigh seated persons, then weight measurement accuracy improves, but the device complexity and cost increase
Solution Approach 1:
Rather than using a single complex specialized scale, the invention segments the weighing function into two simple panels that can be used separately or combined. This segmentation allows accurate seated weighing without requiring a completely specialized complex device
Solution Approach 2:
The control assembly merges the measurements from the first and second panels to provide the total weight. This combining approach allows the system to function as a complete weighing solution while using simpler individual components compared to a single specialized scale
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate weight measurement for seated individuals by combining measurements from the upper and lower body, facilitating precise weight determination without specialized equipment or assistance.
Implementation Method 1
The first panel (12) includes a first weight sensor (20) and is designed to extend across a buttocks area of a person seated thereon to weigh a first portion (62) of the person
Implementation Method 2
The second panel (14) includes a second weight sensor (22) and is designed to extend across soles of feet of a person placed thereon to weigh a second portion (64) of the person

AI summary
A weight scale for weighing seated persons includes a first panel, a second panel, a control assembly, and a power supply. The first panel includes a first weight sensor and designed to extend across a buttocks area of a person seated thereon to weigh a first portion of the person. The second panel includes a second weight sensor and designed to extend across soles of feet of a person placed thereon to weigh a second portion of the person. The control assembly is operatively connected to the first panel and the second panel and includes a control unit to show total weight information of the first portion and the second portion received from the first panel and the second panel. The power supply is designed to supply power to the first panel, the second panel, and the control assembly.
