Liquid Ingress Detection Label With Partial Adhesive Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection labels for electronic devices cannot effectively detect liquid ingress from the side facing the housing due to adhesive coverage, leading to inaccurate fault diagnosis and reduced maintenance efficiency.
Innovation Solution
A detection label design with a reduced adhesive area and through-holes allows liquid to contact a detection part, enabling it to change color or form when liquid enters, facilitating accurate detection in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adhesive layer covers the entire surface of the detection label facing the housing, then the detection label is securely attached to the housing, but liquid cannot permeate through the adhesive layer and the detection label cannot detect liquid ingress from the housing side
Solution Approach 1:
The adhesive layer is segmented into a first adhesive region and a second adhesive region with different properties. The first adhesive region has lower viscosity and allows liquid permeation, while the second adhesive region has higher viscosity and prevents liquid permeation, achieving both secure attachment and liquid detection functionality
Solution Approach 2:
Different regions of the adhesive layer are assigned different local qualities: the first adhesive region is designed with liquid-permeable characteristics for detection, while the second adhesive region is designed with liquid-impermeable characteristics for secure attachment, allowing each region to perform its specific function optimally

Function Achieved in This Case
Improves detection accuracy and maintenance efficiency by allowing the detection part to interact with liquid from any direction, enabling quick identification of liquid ingress and corresponding maintenance actions.
Implementation Method 1
When liquid is in contact with the detection labels, the detection labels change, for example, change the color

AI summary
Embodiments of this application provide a detection label for an electronic device and an electronic device. The detection label includes a detection part and an adhesive layer, where the detection part is configured to detect whether liquid flows into an electronic device, and the adhesive layer is configured to connect the detection part to a housing of the electronic device. Specifically, when being in contact with liquid, the detection part may change significantly, so that a maintainer can determine, by observing the detection part, whether liquid flows into the electronic device. The detection part has a first surface, the first surface is a surface of a side facing towards the housing, the adhesive layer may be disposed on the first surface, and an area of the adhesive layer is less than an area of the first surface. In this way, a part of the first surface is not covered with the adhesive layer, and liquid can be in contact with the first surface, so that the first surface can also be configured to detect whether liquid flows into the electronic device, and the detection part can perform detection in a plurality of directions simultaneously.
