Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric lifting and moving machines for caregivers have large sizes, high chassis, and complex pin-type lifting mechanisms, making them inconvenient for accessing furniture, difficult to operate, and providing poor user experience.
Innovation Solution
An electric lifting and moving machine with a compact design featuring an automatic ascending and descending mechanism, comprising a bearing assembly, a supporting assembly, an electric lifting assembly with a motor driving system, connecting rods, castors, and a foot brake assembly, allowing for easy operation and improved user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a large size and high chassis design is adopted, then the moving machine has sufficient structural strength and stability, but it cannot access some furniture and sofas to perform moving
Solution Approach 1:
The patent implements a height-adjustable chassis through a lifting mechanism with motor driving assembly. The chassis can dynamically change its height position between a first position (higher) and a second position (lower), allowing the moving machine to adapt to different furniture heights and access various surfaces while maintaining structural strength at each position.
2Ease of manufacture
If a pin-type lifting mechanism is adopted, then the lifting function is achieved, but it is complicated to operate and requires users to leave the moving machine to adjust its height
Solution Approach 1:
The patent replaces the traditional manual pin-type lifting mechanism with an electric motor driving assembly. The motor receives electrical signals to drive the lifting mechanism, automating the height adjustment process. Users can control the height change through electrical control rather than manual mechanical operation, simplifying the operating process and eliminating the need for users to leave the machine.
3Ease of operation
If a soft cushion is used to carry a user, then the user comfort is improved, but it does not enable the user to sit for a long time
Solution Approach 1:
The patent divides the bearing assembly into multiple functional components: a soft cushion portion for immediate comfort and a hard support structure (seat board, supporting rods) for sustained support. The soft cushion provides initial comfort while the rigid framework maintains structural integrity and support over extended periods, allowing users to sit for long durations without compromising comfort or structural stability.
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
The machine achieves automatic and efficient ascending and descending with a simple structure and small volume, enhancing user comfort and convenience for caregivers by facilitating easy access to various furniture types.
Implementation Method 1
