Wearable Motorized Device with Nested Wheel Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable motorized devices have low skating stability and are inconvenient for stair climbing due to their length and contour, which exceeds that of the shoe, causing awkwardness and discomfort.
Innovation Solution
A wearable motorized device with wheels installed in parallel on a shoe bracket, embedding the driving motor and battery pack within the wheels, and incorporating a shock pad and flexible design to enhance stability and ease of use, allowing for lateral skating and improved stair navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the battery pack is secured at the raised rear edge of the base plate to provide power, then the power supply capacity is improved, but the longitudinal length of the base increases greatly, causing the contour of the motorized device to exceed the contour of the shoe
Solution Approach 1:
The battery pack is embedded inside one of the wheels, nesting the power supply component within the existing wheel structure rather than adding it as a separate external component. This eliminates the need for additional longitudinal space while maintaining full power supply capacity.
Solution Approach 2:
The battery pack and wheel are merged into a single integrated structure where the battery pack occupies the internal space of the wheel. This combination reduces the overall device length while preserving both the power supply function and the wheel's skating function.
2Stability of the object's composition
If the base is provided with raised side edges and raised rear edge to support the battery pack, then the structural stability is improved, but the general contour of the motorized device far exceeds the contour of the shoe in the longitudinal direction
Solution Approach 1:
The battery pack is nested within the wheel structure, eliminating the need for raised edges to accommodate external battery mounting. The wheel's existing structure provides the necessary support while maintaining a compact contour that matches the shoe.
Solution Approach 2:
The battery pack is extracted from the traditional base plate location and relocated to the wheel structure. This repositioning removes the need for extended raised edges on the base plate while maintaining structural stability through the wheel's inherent design.
3Use of energy by moving object
If the wearable motorized device has a long base contour to accommodate the battery pack, then the power supply capacity is improved, but the wearer has to turn her feet sideways when ascending and descending stairs, causing awkwardness and inconvenience
Solution Approach 1:
The battery pack is nested within the wheel, creating a compact device that fits within the shoe's contour. This allows the wearer to maintain normal foot positioning during stair climbing without the need to turn feet sideways, while still providing adequate power supply capacity.
4Use of energy by moving object
If the battery pack is secured at the raised rear edge of the base plate, then the power supply capacity is improved, but the distance between the two feet with one in front of the other cannot be too large due to the limitation of the human body physique
Solution Approach 1:
The battery pack is nested within the wheel structure, maintaining a compact device profile that allows the wearer to position feet at an optimal distance for skating stability. The compact design does not force the feet too close together, preserving natural skating posture and 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 device provides high skating stability and ease of use by allowing wider leg positioning during skating and reducing strain when ascending or descending stairs, maintaining a contour that does not significantly exceed the shoe's longitudinal direction.
Implementation Method 1
The base plate is provided with a shock pad for absorption of vibration and shock

AI summary
A wearable motorized device comprising a shoe bracket, which can be fastened to a shoe; wheels that are installed on the left and right sides of the shoe bracket in parallel to support the wearer's lateral skating and longitudinal walking; a driving motor for rotationally driving the wheels; and a battery pack for powering the driving motor. The wheels are not coaxially installed on the two sides of the shoe bracket to drive the wearer's longitudinal skating, but instead are installed on the two sides of the shoe bracket in parallel to drive the wearer's lateral skating; the wearer can position his/her legs apart during skating, so the skating stability is improved. Its general contour does not significantly exceed the contour of the shoe in the longitudinal direction, thus and it will not strain the wearer when ascending or descending stairs.
