Solution Overview
Problem
Conventional rollators are often bulky and limited in functionality, typically offering only one or two functions, such as support and limited object transport, making them difficult to manufacture and handle effectively.
Innovation Solution
A multifunction device with a frame unit comprising two spaced frame areas connected by a transverse range, allowing for the integration of various functional units such as seats, storage surfaces, or transport vessels, with rotatable rolling bodies and a stable design that enhances usability and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rollators are equipped with pockets set on the frame, then limited object transport function is provided, but the device becomes bulky and structurally complex
Solution Approach 1:
The frame is divided into modular components: a base frame unit and separate functional units (seats, storage compartments, transport vessels) that can be independently attached and detached. This segmentation allows the core frame to remain simple while functionality is added through standardized attachments, resolving the contradiction between versatility and structural complexity.
Solution Approach 2:
The frame unit is designed with universal attachment features (first and second holding portions) that can accommodate multiple types of functional units. A single frame structure supports diverse functions including seating, storage, and transport by simply changing which functional units are attached, avoiding the need for complex integrated designs.
2Adaptability or versatility
If multiple functional units are integrated into the frame, then versatility is improved, but manufacturing difficulty increases
Solution Approach 1:
By separating the frame from functional units, each component can be manufactured independently using optimized processes. The frame is produced as a standardized base unit, while functional units can be manufactured separately and attached via simple connection mechanisms, significantly easing overall manufacturing compared to integrated multi-functional designs.
Solution Approach 2:
The standardized holding portions and attachment mechanisms allow the same frame design to support multiple functional units. This universality means the frame itself needs to be manufactured only once as a base unit, while different functional units can be produced separately and interchanged, reducing manufacturing complexity.
3Stability of the object's composition
If the frame areas are connected via transverse ranges with spaced configuration, then stability is improved, but device complexity increases
Solution Approach 1:
The first and second holding portions are integrated into a single frame unit design, combining stability features with the base structure. The transverse ranges connecting spaced frame areas are incorporated as standard frame elements rather than separate additions, achieving enhanced stability without proportionally increasing overall complexity.
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 multifunction device provides a versatile, easy-to-manufacture, and handle solution that supports multiple functions, improving user safety and convenience by enabling a wider range of applications while maintaining stability and ease of use.
Implementation Method 1
The rolling bodies can preferably be designed as solid rubber rollers running on plastic rims. Alternatively, the rolling bodies are formed by solid body-shaped polyurethane, which improves the racing of the multifunction device due to the lower hardness.
