Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high weight of battery packs integrated into electric vehicle luggage compartments makes them difficult for owners to remove or place, reducing luggage capacity and posing handling and crashworthiness challenges.
Innovation Solution
A detachable battery system comprising removable battery modules and a support fixed to the vehicle body, allowing easy installation and removal of lightweight modules, which can be connected in series or parallel to extend vehicle range, with integrated electrical and structural connectors for secure fixing and power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If heavy battery packs are integrated into the luggage compartment, then the vehicle's energy storage capacity is improved, but the weight increases making removal and placement impossible for car owners and reducing luggage capacity
Solution Approach 1:
The battery system is divided into multiple detachable modules that can be independently handled. Each module weighs less than 15kg, making them manageable for car owners while collectively providing the required energy storage capacity when multiple modules are installed in the luggage compartment.
2Quantity of substance
If heavy battery packs are integrated into the luggage compartment, then the vehicle's energy storage capacity is improved, but the luggage capacity is considerably reduced
Solution Approach 1:
The battery system uses multiple small modular units that can be flexibly arranged in the luggage compartment. This segmentation allows for optimized space utilization compared to a single large battery pack, potentially improving both energy storage density and available luggage space.
3Ease of operation
If detachable battery modules are used, then the ease of operation is improved allowing car owners to easily install and remove modules, but the device complexity increases requiring multiple connectors and fixing mechanisms
Solution Approach 1:
The electrical connector and structural fixing mechanisms are integrated into a single unified connection interface. When a battery module is inserted, both the electrical connection and mechanical fixation occur simultaneously through one action, eliminating the need for separate connector assembly steps and reducing operational complexity.
4Reliability
If multiple connectors are integrated into the support, then the reliability is improved ensuring secure electrical and structural connection, but the device complexity increases
Solution Approach 1:
Multiple electrical contacts and grounding paths are integrated into a single connector assembly that establishes all necessary electrical connections simultaneously upon module insertion. This merging approach maintains comprehensive electrical connectivity and reliability while presenting a single simple interface to the user.
