Detachable Cooling Box With Wireless Charging Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles with integrated device batteries become cumbersome when used outside the vehicle, as the battery power depletes, requiring recharging within the vehicle, which limits convenience when using devices like cooling boxes, cameras, or air conditioners outside.
Innovation Solution
A vehicle design featuring a detachable cooling box with a chargeable and dischargeable driving battery, a charger, and multiple detachable batteries that can be attached to the cooling box, allowing for external use and easy battery replacement or recharging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each device is provided with an integrated battery, then the device can be used outside the vehicle, but the battery becomes cumbersome to carry and requires recharging in the vehicle
Solution Approach 1:
The battery system is segmented into a stationary charging base (in the vehicle) and a portable battery unit (in the cooling box). The cooling box is divided into a main body and a detachable battery pack, allowing the battery to be separated from the device. This enables the device to be used outside the vehicle without carrying the entire battery, as the battery can be recharged at the stationary base.
Solution Approach 2:
A wireless power transmission intermediary is introduced between the stationary battery base and the portable cooling box battery. The base transmits power wirelessly to the cooling box battery when placed on top of it, eliminating the need for physical battery handling or cable connections. This intermediary power transmission mechanism resolves the contradiction by enabling convenient outdoor use while maintaining easy recharging through wireless contact with the base.
2Ease of operation
If the cooling box is made detachable from the vehicle, then portability is improved, but power supply reliability deteriorates
Solution Approach 1:
The power supply system is segmented into a large-capacity stationary base battery and a smaller portable cooling box battery. The cooling box battery can be recharged at the stationary base, which has sufficient power capacity. This segmentation allows the cooling box to be portable while the stationary base ensures reliable power supply and charging capacity.
Solution Approach 2:
The stationary battery base is prepared in advance with sufficient charge capacity to multiple recharge the portable cooling box battery. This preliminary action ensures that even when the cooling box is detached and used outside the vehicle, power supply reliability is maintained because the base battery is pre-charged and ready to replenish the portable battery as needed.
3Ease of manufacture
If a charger is provided in the vehicle, then battery recharging is enabled, but the charger occupies space in the vehicle interior
Solution Approach 1:
The charging function is merged with the stationary battery base, which is positioned in the vehicle's trunk or storage compartment rather than the passenger cabin. The base serves dual purposes: storing power and providing charging capability. This merging eliminates the need for a separate dedicated charger in the vehicle interior, as the battery base itself provides the charging function.
Solution Approach 2:
Wireless power transmission technology serves as an intermediary that eliminates the need for a physical charger device in the vehicle interior. The base transmits power wirelessly to the cooling box battery when placed on top of it, replacing the traditional charger hardware with a contactless power transfer mechanism that requires no additional space in the passenger compartment.
