Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex lifting device with additional balance weight is used, then the lifting function is achieved, but the device complexity and cost increase
Solution Approach 1:
The patent removes the additional balance weight component from the system, extracting only the essential lifting function through the airbag mechanism. The airbag directly provides the lifting force without requiring separate counterweight systems, thereby simplifying the overall device structure while maintaining reliable lifting functionality.
Solution Approach 2:
The airbag serves multiple functions simultaneously: it provides the lifting force, acts as the lifting mechanism itself, and eliminates the need for separate balance weight systems. This multi-functionality reduces device complexity while ensuring the lifting function is achieved through a unified component.
2Reliability
If a complex lifting device is used, then the lifting function is achieved, but the assembly process becomes cumbersome
Solution Approach 1:
The lifting device is segmented into modular components: the airbag, the waist loop, the fixing straps, and the connecting mechanisms. Each component can be independently manufactured and assembled, making the assembly process more manageable and less cumbersome while ensuring the lifting function is properly implemented.
Solution Approach 2:
By removing the additional balance weight and associated complex assembly requirements, the patent extracts only the essential lifting components. This reduction in component count directly simplifies the assembly process while maintaining the core lifting function through the airbag mechanism.
3Reliability
If a complex lifting device is used, then the lifting function is achieved, but the operation becomes difficult for a single person
Solution Approach 1:
The airbag system is designed to be self-regulating and automatically provides the lifting force once inflated. The user simply needs to inflate the airbag through the pump system, and the lifting function activates automatically without requiring complex manual adjustments or operations, making it easy for a single person to operate.
Solution Approach 2:
By removing the additional balance weight and complex adjustment mechanisms, the patent extracts only the essential operational elements. The simplified system requires minimal user intervention - primarily inflation control - making the operation accessible to a single person while maintaining reliable lifting function.
4Reliability
If a complex lifting device is used, then the lifting function is achieved, but the cost increases
Solution Approach 1:
The patent removes the additional balance weight and associated complex mechanical components, extracting only the essential lifting function provided by the airbag system. This reduction in component count and complexity directly lowers manufacturing costs while maintaining the lifting function through the simpler, more economical airbag mechanism.
Solution Approach 2:
The airbag system uses relatively simple, cost-effective materials and components compared to complex mechanical lifting systems. The airbag and associated pump system represent a more economical solution that achieves the lifting function without requiring expensive precision mechanical components, thereby reducing overall device cost.
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 mechanism is lightweight, requires no additional balance weight, is easy to maintain, and reduces costs while providing convenient height adjustment for users of varying heights.
Implementation Method 1
The air pressure inside the airtight chamber is higher than the air pressure outside the airtight chamber, resulting in an air pressure difference. The air pressure difference (which can provide a variable lifting force to reduce the walking load) is used to generate buoyancy for the patient.
