Capacitor Unit With Cavity For Contactless Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In contactless power supply systems, longer parallel transmission lines increase impedance, reducing power reception efficiency, and adding more capacitors to mitigate this can obstruct automated guided vehicles. Existing solutions do not effectively compactly arrange capacitors and connection units while minimizing impedance and protecting against damage.
Innovation Solution
A capacitor unit with a compact design, featuring a capacitor and connection unit integrated into a capacitor plate with a cavity that can be filled or covered, allowing for flexible connection configurations and protection, reducing impedance and preventing damage from external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the number of capacitors connected to the parallel transmission line is increased to reduce impedance, then the power reception efficiency is improved, but the automated guided vehicles are obstructed
Solution Approach 1:
The capacitor and connection unit are integrated into a single compact capacitor unit structure, merging previously separate components into one space-efficient assembly that reduces overall footprint while maintaining electrical functionality
Solution Approach 2:
The connection unit is nested within the capacitor plate structure, with the capacitor housed inside a cavity formed in the capacitor plate, creating a nested arrangement that minimizes space occupation
2Length of moving object
If the capacitor unit is made compact to avoid obstructing vehicles, then the space for vehicle travel is preserved, but the capacitor and connection unit become vulnerable to damage from external forces
Solution Approach 1:
The cavity within the capacitor plate is filled with a filler material that acts as a cushioning element, protecting the capacitor and connection unit from damage due to external forces such as stepping on the capacitor unit
Solution Approach 2:
The capacitor plate structure with its cavity and filler creates a flexible protective enclosure that absorbs impact forces while maintaining the compact form factor
3Reliability
If the capacitor and connection unit are separately arranged with spacers, then the components are protected, but the number of components increases and space is wasted
Solution Approach 1:
The capacitor plate integrates multiple functions into a single component: it provides structural support, forms a protective cavity, and eliminates the need for separate spacer components by incorporating spacing functionality directly into its structure
Solution Approach 2:
The capacitor plate serves multiple purposes simultaneously: it acts as a structural support element, a protective enclosure through its cavity, and a spacing mechanism, thereby reducing the total number of components needed
