Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of personal mobility devices, such as electric kickboards and bicycles, is cumbersome due to the need for manual operation of parking stands, and these devices often unstable when parked, especially on irregular surfaces.
Innovation Solution
A parking system for personal mobility devices that includes a first and second parking stand, a parking motor, and a power transmission device, allowing for automatic unfolding and folding of the stands, and adjustable unfolding degrees based on the parking surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a single parking stand is used, then the device structure is simple, but the personal mobility cannot be stably supported and may fall down
Solution Approach 1:
The single parking stand is divided into two separate parking stands (first and second parking stands) that can be independently controlled. Each stand operates separately to provide balanced support, preventing the personal mobility from falling while maintaining manageable structural complexity through modular design
2Ease of operation
If manual operation of parking stand is required, then the device structure is simple, but the use becomes cumbersome
Solution Approach 1:
The parking stand system performs automatic unfolding and folding operations without requiring manual intervention from the user. The control unit autonomously manages the motor-driven mechanisms to position the parking stands, eliminating cumbersome manual operation while the simple control interface maintains ease of use
Solution Approach 2:
The manual mechanical operation of unfolding and folding parking stands is replaced with an automated motor-driven system. The motor converts electrical energy to mechanical motion, substituting human physical effort with an automated actuation mechanism controlled by a control unit
3Stability of the object's composition
If the parking stand is located on one side, then the device structure is simple, but the personal mobility cannot be stably supported in an inclined state
Solution Approach 1:
The system uses two parking stands positioned at different locations (front and rear sides) of the personal mobility, creating an asymmetric configuration that provides stable support on inclined surfaces. Each stand is independently controllable, allowing adaptive positioning to counteract gravitational forces on slopes while maintaining manageable structural complexity
4Adaptability or versatility
If fixed unfolding degree is used, then the device structure is simple, but the personal mobility cannot adapt to irregular surfaces
Solution Approach 1:
The parking stand system transitions from fixed unfolding degrees to dynamically adjustable unfolding angles. The motor-driven mechanism allows continuous variation of the unfolding degree, enabling the parking stands to adapt to irregular surfaces and different parking conditions while the control unit manages the complexity of dynamic adjustment
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 system enables convenient and stable parking of personal mobility devices by automatically unfolding and folding the parking stands, and adjusting their angle to suit the surface, thereby preventing the device from falling.
Implementation Method 1
a power transmission device configured to transmit a rotational force of the parking motor to shafts of the first and second parking stands to simultaneously rotate the first and second parking stands in opposite directions
Implementation Method 2
The power transmission device may include a first driven bevel gear coupled to the shaft of the first parking stand, a second driven bevel gear coupled to the shaft of the second parking stand, and a driving bevel gear having opposite sides engaged with the first and second driven bevel gears
