Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedside steps are simple in structure, lack supporting parts, and are difficult to discern in the dark, making them inconvenient for elderly or patients with weak legs or feet, and unable to adapt to various environments.
Innovation Solution
A bedside step with an underframe, base plate, sideframe, sensor lamps, and a sensor that activates the lamps when a user approaches, allowing light transmission through holes in the base plate for easy positioning in the dark, and adjustable components for user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple bedside step structure is used, then the device complexity is reduced, but the functionality and ease of operation deteriorate
Solution Approach 1:
The bedside step integrates multiple functions into a single device: it provides step functionality for getting on/off bed, incorporates sensor lamps for illumination in dark environments, includes support rods for structural stability, and features adjustable components for customization. This multi-functional design resolves the contradiction by enhancing ease of operation through additional features while maintaining relatively simple overall structure.
2Illumination intensity
If sensor lamps are added to the bedside step, then the illumination capability in dark environments is improved, but the device complexity increases
Solution Approach 1:
The sensor lamps are integrated directly into the bedside step structure, merging the illumination function with the existing step framework. The lamps are positioned within the step body, sharing the same structural space, which provides lighting functionality without proportionally increasing overall device complexity.
Solution Approach 2:
The sensor lamps are equipped with automatic sensing capabilities that detect user approach and activate illumination automatically. This self-service mechanism eliminates the need for manual switching or complex control systems, providing enhanced lighting while maintaining simple operation and relatively low device complexity.
3Stability of the object's composition
If support rods are added to the bedside step, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The support rods are designed as separate, modular components that can be independently positioned and adjusted within the bedside step structure. This segmentation allows for enhanced structural stability through distributed support while keeping each individual component simple and the overall assembly relatively straightforward.
