Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If lithium batteries are used to power medical capsules, then the power capacity is sufficient, but the safety cannot be verified in wide applications
Solution Approach 1:
The battery system is divided into multiple individual battery units (at least two batteries) connected in series. Each battery can be independently selected from safe types (silver oxide, zinc air, or lithium batteries), allowing the system to achieve sufficient total power capacity while maintaining safety through the use of proven safe battery chemistries in modular units.
2Device complexity
If a fixed voltage battery pack is used, then the structure is simple, but it cannot provide different voltages to different electrical components
Solution Approach 1:
An intermediate connector is introduced as a mediator between the battery pack and the electrical components. This connector can be selectively connected to different tap points (intermediate connection points) on the battery pack, enabling the system to output different voltages (total voltage or partial voltages) to different components without changing the battery pack structure itself.
Solution Approach 2:
The voltage output configuration is made dynamic and adjustable. The intermediate connector can be repositioned or reconnected to different tap points on the battery pack, allowing the system to adaptively provide different voltage levels to different electrical components based on their specific power requirements.
3Adaptability or versatility
If multiple connectors are added to output various voltages, then the voltage versatility is improved, but the risk of short circuit increases
Solution Approach 1:
Insulation assemblies are introduced as intermediary protective elements between the multiple connectors and the battery pack. These insulation assemblies (including insulation sheets and insulation gaskets) physically isolate conductive parts, preventing unintended electrical contact and short circuits while allowing the system to maintain multiple voltage output capabilities through the intermediate connector.
