Electric Kickboard Impact Absorbing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric kickboards inadequately absorb impacts applied to the knee or waist of users due to their simple structure and weight distribution, leading to insufficient shock absorption and discomfort during riding.
Innovation Solution
An impact absorbing device using a combination of coil springs with different spring constants is integrated into the electric kickboard, distributing user weight and absorbing vibrations, while a self-power generating device harnesses vertical vibrations to produce electricity for extended riding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple structure with basic suspension unit is used, then the device complexity is reduced and weight is minimized, but the impact absorbing function becomes insufficient
Solution Approach 1:
The suspension system is segmented into multiple independent components: a first suspension unit positioned at the front and a second suspension unit positioned at the rear. Each unit independently absorbs impacts from different directions and locations, providing comprehensive impact protection while maintaining relatively simple individual component designs
Solution Approach 2:
The suspension units are positioned at different locations (front and rear) along the length of the kickboard, creating a distributed suspension system that addresses impacts from multiple spatial dimensions rather than relying on a single centralized suspension point
2Weight of moving object
If the user stands on the deck, then the kickboard maintains a simple lightweight structure, but the impact to knee or waist cannot be sufficiently absorbed
Solution Approach 1:
The suspension units act as intermediary elements between the wheel and the deck, absorbing impacts before they are transmitted to the user's body. The first suspension unit absorbs front impacts while the second suspension unit absorbs rear impacts, preventing direct transmission of harmful forces to the user's knee or waist
3Reliability
If a high functional suspension unit is installed, then the impact absorbing capacity is improved, but the structure becomes more complex and weight increases
Solution Approach 1:
Instead of using one complex high-capacity suspension unit, the system divides the suspension function into two simpler units positioned at the front and rear. Each unit handles specific directional impacts, allowing for simpler individual designs while achieving comprehensive impact absorption when both units work together

Function Achieved in This Case
The impact absorbing device effectively reduces physical stress on the user by distributing weight and absorbing shocks, while the self-power generating device extends the kickboard's range by converting vibrations into usable energy.
Implementation Method 1
an impact absorbing device capable of preventing excessive shakings and vibrations generated while absorbing the impact by using a coil spring
Implementation Method 2

AI summary
The present invention relates to an electric kickboard in which an impact absorbing device is installed, and more particularly, to an electric kickboard including an impact absorbing device to support a weight of a user standing up by allowing the impact absorbing device to sufficiently absorb an impact when a seat is vibrated during riding by using elasticity of springs having different spring constants and including a self-power generating drive at one side thereof to produce electricity using vertical vibrations during riding and accumulate the produced electricity, thereby improving an energy efficiency.
