Washable Handset Shell Segmentation for Dishwasher Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices, such as handsets, often require sanitization but are difficult to clean without damaging the electronics, and waterproofing solutions can interfere with device functionality and audio quality.
Innovation Solution
A washable shell for handheld electronic devices that can be easily assembled and disassembled by hand, made from dishwasher-safe materials like ABS, allowing for effective cleaning without tools and preserving electronic functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is made waterproof to enable washing, then cleaning effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The device is divided into two separable parts: a washable shell and non-washable electronics. The shell can be detached and washed independently in a dishwasher, while the electronics remain separate and protected from water exposure. This segmentation allows the cleaning function to be applied only to the appropriate component.
Solution Approach 2:
The electronics are extracted from the shell and kept as a separate component. This extraction allows the shell to be designed for easy washing without compromising the electronics, eliminating the need for complex waterproofing of the entire device.
2Reliability
If waterproofing is applied to protect electronics, then cleaning capability is improved, but audio quality deteriorates
Solution Approach 1:
The device is segmented into a washable shell and non-washable electronics, allowing the shell to be cleaned without waterproofing that would interfere with audio components.
Solution Approach 2:
The electronics are taken out from the shell, eliminating the need for waterproofing measures that would otherwise degrade audio quality.
3Strength
If the shell is made permanently attached to ensure structural integrity, then device strength is improved, but ease of cleaning deteriorates
Solution Approach 1:
The shell is segmented into detachable parts that can be easily separated for washing and reassembled afterward, maintaining structural integrity when assembled while enabling easy cleaning when disassembled.
Solution Approach 2:
The connection between shell parts is dynamic rather than fixed - designed to be easily assembled and disassembled by hand without tools, providing both strength when assembled and ease of cleaning when disassembled.

AI summary
The shell of an electronic handheld device is adapted for easy and repeated—even frequent—assembly with and disassembly from the electronics, and the shell is washable, preferably in a dishwasher. Preferably, the shell comprises a plurality of parts that can be easily and repeatedly assembled and disassembled by hand without use of tools. For example, the parts of a telephone handset shell are made to be easily snapped together around, and unsnapped from, the handset's electronics, thereby enabling the shells of the handsets of telephones to be washed to have this function performed by unskilled personnel.
