Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rechargeable battery devices are used to operate without a cable connection, then mobility and independence from power supply lines are improved, but the duration of action is limited due to quick exhaustion of on-board batteries
Solution Approach 1:
A mobile energy store serves as an intermediary device between the public power supply and the rechargeable battery devices. It receives electrical energy from the public power supply via a rechargeable battery interface and outputs energy to rechargeable batteries, enabling continuous operation of power tools without being constrained by the limited capacity of on-board batteries.
2Duration of action of moving object
If a mobile energy store is designed to provide stable electrical energy supply, then the duration of action is improved, but the weight of the moving object increases
Solution Approach 1:
The mobile energy store employs a modular storage unit comprising multiple rechargeable battery modules that can be stacked vertically. This segmentation allows the system to provide extended energy supply duration by adding more modules as needed, while maintaining manageable weight through distributed mass and optional modular configuration.
Solution Approach 2:
The heavy energy storage capacity is extracted from the individual power tools and consolidated into a separate mobile energy store. This allows the power tools to remain lightweight and portable, while the energy store provides the necessary energy capacity through its dedicated storage unit with multiple battery modules.
3Ease of operation
If the storage unit is designed with modular structure for easy transportation, then ease of operation is improved, but the stability of the object's composition is worsened
Solution Approach 1:
The storage unit is divided into multiple identical rechargeable battery modules that can be stacked vertically and connected through standardized interfaces. This segmentation enables easy transportation by allowing the stack to be separated into individual modules or smaller groups, while the standardized connection interfaces maintain stable and reliable electrical and mechanical connections when assembled.
