Solution Overview
Problem
Existing weight measurement devices in hospitals, such as bed scales, seat scales, and floor scales, are bulky and require significant space, limiting their placement and necessitating multiple purchases for different positions, and are cumbersome to transform.
Innovation Solution
A retractable multi-shaped scale with retractable platforms and adjustable height, allowing conversion between standing, sitting, and lying positions, featuring a telescopic rod for height adjustment and a support system for stability, with an operation panel for easy shape change and weight measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate weight measurement devices (bed scales, seat scales, floor scales) are used for different positions, then measurement versatility is improved, but space requirements and device complexity increase
Solution Approach 1:
The scale integrates multiple measurement functions (standing, sitting, lying positions) into a single device. The platform can transform between different configurations through telescopic mechanisms and adjustable components, allowing one device to replace multiple separate scales, thereby reducing space requirements while maintaining measurement versatility
Solution Approach 2:
The scale employs nested telescopic platforms where the sitting platform can be retracted into the standing platform structure, and the lying platform can be folded or retracted. This nesting mechanism allows the device to compact its size for storage while expanding to full measurement configurations when needed, effectively reducing the occupied space
2Adaptability or versatility
If multiple separate weight measurement devices are used for different positions, then measurement versatility is improved, but device complexity and cost increase
Solution Approach 1:
The scale uses a unified measurement system with a single weight sensor and control unit that serves all measurement positions (standing, sitting, lying). This centralized approach reduces device complexity compared to having separate measurement systems for each position, while still providing comprehensive measurement capabilities
Solution Approach 2:
The invention combines the measurement functions, control systems, and data processing units into an integrated system. The single weight sensor and unified control interface replace what would otherwise be multiple separate device systems, reducing overall complexity while maintaining versatility
3Measurement precision
If traditional weight scales are used, then measurement accuracy is maintained, but ease of operation and mobility are reduced
Solution Approach 1:
The scale automatically detects the measurement position (standing, sitting, or lying) and adjusts its configuration accordingly without requiring manual intervention. The telescopic platforms and adjustable components are driven by automated mechanisms that respond to user selection or sensor input, making the device self-adjusting and easier to operate while maintaining measurement accuracy through the unified weight sensor system

AI summary
A retractable multi-shaped scale comprises a retractable part consisting of a fixed platform, a first retractable platform, a second retractable platform, a support part for supporting and transmitting weight. The support part includes multiple support frames, with one end pivotally attached to the lower edge of the fixed platform and the other end pivotally attached to a base located at the bottom of the scale. The base contains at least one weight sensor to obtain measurement results. a telescopic rod, with one end pivotally attached to the base and the other end pivotally attached to the support part, is used to drive the support frames from a horizontal to a vertical position, further adjusting the distance between the base and the retractable part. An operation panel is connected to the weight sensor to display the measurement results obtained by the weight sensor.
