Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple personal mobility devices are purchased for different purposes, then each device can be optimized for its specific function, but the cost burden increases and storage space is consumed
Solution Approach 1:
The patent implements a universal base platform that can accommodate multiple types of upper modules through standardized coupling mechanisms. The base platform includes a motor, battery, and control system that can work with different modules such as scooters, wagons, and strollers, allowing one device to perform multiple functions that previously required separate devices
Solution Approach 2:
The personal mobility device is divided into two main segments: a reusable base platform and interchangeable upper modules. This segmentation allows the base platform to remain while only the upper module needs to be changed for different purposes, reducing the total number of devices needed from multiple complete devices to one base platform plus various modules
2Adaptability or versatility
If a single device is designed to accommodate multiple upper modules, then cost and storage issues are resolved, but the device complexity increases due to coupling mechanisms
Solution Approach 1:
A universal coupling mechanism is designed with standardized interfaces including insert-type couplers and hook couplers that can accommodate different upper module types. The coupling mechanism uses common components such as coupling pins, fixing holes, and connection bars across different module types, reducing the complexity that would arise from designing unique coupling systems for each module
3Ease of operation
If upper modules are easily replaceable with simple coupling mechanisms, then ease of operation is improved, but the reliability of the connection may be compromised
Solution Approach 1:
The coupling mechanism is segmented into multiple independent components that work together: insert-type couplers for initial engagement, hook couplers for securing, coupling pins for locking, and folding restrictors for position maintenance. This segmentation allows each component to perform a specific function, making the overall system both easy to operate and reliable
Solution Approach 2:
The coupling mechanism incorporates redundant connection elements such as both insert-type couplers and hook couplers working together, and folding restrictors that engage beforehand to prevent accidental folding. These preemptive measures ensure that even if one connection element fails, the module remains securely attached

AI summary
A modular interchangeable mobility device comprises an electric platform comprising a base platform which comprises wheels, a motor to drive the wheels and a battery to supply power to the motor, and an upper coupling part configured to be detachably coupled with an upper module located on the base platform, and a folding-type chair attached to the base platform and configured to provide a space for the upper module when folded and serve when unfolded as a seat such that the modular interchangeable mobility device may be used as an electric scooter.
