Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery and capacitor hybrid systems require complex wire connections to connect batteries and capacitors in parallel, making it difficult to couple them easily and increasing manufacturing costs.
Innovation Solution
A battery and capacitor hybrid assembly structure is designed with a cylindrical metal casing that houses both components, using a circular metal cover plate and insulating sealing members to electrically connect them in parallel, reducing the number of components needed for coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate wire connections are used to connect battery and capacitor in parallel, then electrical connection is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the battery and capacitor into a single integrated hybrid assembly housed within one cylindrical casing. The battery and capacitor are positioned concentrically with the battery outer shell enclosing the capacitor, eliminating the need for separate wire connections and external mounting structures. This integration directly reduces device complexity while maintaining reliable electrical connection through shared terminals.
2Reliability
If complex wire connections are used to couple battery and capacitor, then electrical connection is established, but ease of manufacture decreases
Solution Approach 1:
The hybrid assembly is segmented into distinct functional modules: the battery as an outer shell unit, the capacitor as an inner cylindrical unit, and insulating sealing members as independent components. This segmentation allows each component to be manufactured separately using optimized processes and then assembled together, significantly improving ease of manufacture compared to creating complex wire connections and integrated assemblies.
Solution Approach 2:
The capacitor is nested within the battery assembly, with the capacitor outer shell fitting inside the battery outer shell. This nested configuration simplifies manufacturing by allowing the inner capacitor to be installed into the pre-assembled battery unit, reducing assembly complexity and improving ease of manufacture while maintaining reliable electrical connections through aligned terminals.
3Reliability
If multiple components are used for coupling battery and capacitor, then connection reliability is improved, but manufacturing cost increases
Solution Approach 1:
The insulating sealing members serve multiple functions simultaneously: they provide electrical insulation between the battery and capacitor outer shells, seal the interface between components to prevent electrolyte leakage, and provide mechanical support for maintaining the concentric arrangement. This multi-functionality reduces the number of separate components needed, lowering manufacturing cost while maintaining connection reliability.
