Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddled electric-powered vehicles with large loading platforms face challenges in securing sufficient battery capacity, ease of battery attachment/detachment, and downsizing the vehicle body, while maintaining convenience and durability.
Innovation Solution
The vehicle features a battery case with approximately rectangular parallelepiped batteries housed below the seat, press holders for secure attachment/detachment, a rear carrier for baggage, and an operation lever for connecting/disconnecting terminals, allowing batteries to be inclined and detached without interference, enhancing ease of use and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If two portable batteries are arranged next to each other in the vehicle width direction to secure a large loading platform area, then the loading platform area is increased, but the battery capacity becomes insufficient
Solution Approach 1:
The patent transitions from arranging batteries horizontally (in the vehicle width direction) to arranging them vertically (in the vehicle height direction) by utilizing the space below the seat. This dimensional change allows the loading platform area to be maximized while accommodating sufficient battery capacity through vertical stacking of multiple batteries.
2Area of stationary object
If batteries are arranged horizontally to maximize loading platform area, then the loading platform is enlarged, but the number of batteries that can be accommodated is reduced
Solution Approach 1:
The patent utilizes the vertical space below the seat to arrange multiple batteries in the height direction, thereby accommodating greater total battery weight and capacity without compromising the loading platform area. This vertical arrangement enables multiple batteries to be stacked efficiently within the available volume.
3Reliability
If pressing holders are provided for each battery to secure attachment, then the attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The pressing holder is divided into multiple independent pressing portions, with each portion corresponding to a specific battery. This segmentation allows each battery to be pressed and secured independently, improving attachment reliability while maintaining manageable structural complexity through modular design.
4Quantity of substance
If batteries are arranged vertically below the seat, then the battery capacity is increased, but the ease of attaching and detaching batteries is reduced
Solution Approach 1:
The pressing holder is designed with movable pressing portions that can dynamically adjust their position and pressing force. This dynamic capability allows the pressing portions to accommodate batteries during attachment, secure them firmly when installed, and release them easily during detachment, thereby improving ease of operation despite vertical arrangement.
5Reliability
If multiple pressing portions are provided in the pressing holder for each battery, then the securing reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The pressing holder is designed with multiple pressing portions that are segmented and can be manufactured as separate components or modules. This segmentation allows each pressing portion to be optimized and manufactured independently, improving securing reliability while facilitating easier assembly and manufacturing through modular construction.
