Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor work vehicles with built-in stationary batteries face limitations in energy storage capacity, affecting professional users' ability to perform multiple tasks outdoors for extended periods due to changes in center of gravity, appearance, and user convenience.
Innovation Solution
The outdoor work vehicle incorporates a dual energy storage system with a first energy storage device comprising multiple first energy storage units and a second energy storage device that is detachable, providing flexible power supply options and improved stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple battery packs are mounted to increase energy storage capacity, then the power supply duration is extended, but the center of gravity changes and user convenience deteriorates
Solution Approach 1:
The energy storage system is divided into a first energy storage device (integrated) and a second energy storage device (detachable). The second energy storage device can be removed and carried separately, allowing users to take only the necessary battery capacity with them, thus maintaining convenience while providing extended power supply options when needed.
Solution Approach 2:
The solution transitions from a single-dimension problem (fixed battery capacity in the vehicle) to a two-dimension solution by separating the energy storage function into integrated and detachable components. This allows the system to adapt to different usage scenarios by combining or separating the battery packs as needed.
2Duration of action of moving object
If multiple battery packs are mounted to increase energy storage capacity, then the power supply duration is extended, but the appearance and size of the vehicle change
Solution Approach 1:
By separating the energy storage system into integrated and detachable components, the vehicle maintains its original appearance when the detachable second energy storage device is removed, while still providing the option to extend power supply duration by attaching additional battery packs when needed.
3Device complexity
If a built-in stationary battery is used, then the structure is simple, but the energy storage capacity is limited
Solution Approach 1:
The second energy storage device is designed with multi-functionality: it can be attached to the vehicle to extend energy storage capacity, removed for portable use, or used to power external devices via the output interface. This universal design allows a single component to serve multiple purposes without significantly increasing system complexity.
4Quantity of substance
If multiple battery packs are mounted, then the energy storage capacity increases, but the mounting positions affect the center of gravity
Solution Approach 1:
The energy storage system transitions from a static fixed configuration to a dynamic configurable system. The second energy storage device can be attached or removed based on operational needs, allowing the center of gravity to be adjusted dynamically rather than being fixed by permanent mounting positions.
