C-Shaped Charging Base with Beveled Surface for Medical Device Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current charging bases for medical devices are not designed to optimize sanitary conditions and do not allow for ergonomic placement of rechargeable assemblies, leading to issues with debris accumulation and user convenience.
Innovation Solution
A C-shaped charging base with a beveled surface and notch configuration that holds a rechargeable assembly in both a charging and ready position, featuring a charging element beneath the beveled surface for easy cleaning and ergonomic positioning, and made from materials that are waterproof and bacterial-resistant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional charging base design is used, then the charging function is provided, but liquid and debris accumulate on surfaces and interfaces, compromising sanitary conditions
Solution Approach 1:
The charging element is extracted from the traditional flat surface and placed beneath the beveled surface, removing the interface where debris would accumulate. This extraction eliminates the harmful accumulation zone while maintaining the charging function through wireless power transfer through the beveled surface.
Solution Approach 2:
The beveled surface introduces a sloped, curved geometry instead of flat surfaces, causing liquid and debris to naturally drain away from the charging area toward the edges, preventing accumulation and improving sanitary conditions.
2Ease of operation
If a traditional charging base design is used, then charging is provided, but the device cannot be placed in an ergonomic position
Solution Approach 1:
The C-shaped housing employs asymmetric geometry with a beveled surface at a specific angle, creating an ergonomic inclination for device placement. This asymmetric design allows the device to rest at a comfortable angle for user interaction while maintaining structural integrity.
Solution Approach 2:
The design transitions from a two-dimensional flat charging surface to a three-dimensional C-shaped structure with a beveled surface, adding dimensional complexity that enables ergonomic positioning while maintaining manufacturing feasibility through molding techniques.
3Object-affected harmful factors
If surfaces are designed to collect liquid and debris, then cleaning is simplified, but sanitary conditions are compromised
Solution Approach 1:
The beveled surface converts the harmful accumulation of liquid and debris into a beneficial drainage system, where the slope naturally directs contaminants away from the charging area toward drainage openings, transforming a potential sanitation problem into an automatic cleaning mechanism.

AI summary
A charging base has a generally C-shaped housing and a charging element. The generally C-shaped housing has an upper part and a lower part. The upper part has an upper surface substantially parallel to a lower surface and an opening extending from the upper surface to the lower surface. The opening has a first width and a second width. A notch is located at the intersection of the first width and the second width. The lower part has a beveled surface generally parallel to and beneath the lower surface of the upper part. The charging element, which provides power to recharge a battery, is located beneath the beveled surface of the lower part. The opening and notch are configured to hold a rechargeable assembly alternately in a first charging position and a second ready position
