Control Panel Water Drainage via Adhesive Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional control panels for outdoor devices suffer from water permeation through the adhesive of interface labels, leading to accumulation and reduced functionality due to obscured displays and decreased touch sensitivity, with existing solutions increasing costs and reliability issues.
Innovation Solution
A control panel design featuring a transparent or translucent display sheet with an interface label and an adhesive layer, where cavities between the label and sheet are connected by water guiding grooves to discharge accumulated water, preventing adhesive immersion and maintaining key sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If double-sided tape with denser structure and increased adhering area is used, then water permeation is prevented, but cost increases and reliability does not improve
Solution Approach 1:
The interface label is divided into functional areas (with cavities) and non-functional areas (with adhesive). This segmentation allows water to be discharged through the functional areas while maintaining adhesion in non-functional areas, preventing water accumulation without requiring denser tape throughout the entire label.
Solution Approach 2:
Adhesive is removed from specific functional areas to create cavities that serve as water discharge pathways. This extraction of adhesive from key areas allows trapped water to escape while adhesive remains in peripheral areas to maintain structural integrity.
2Ease of operation
If adhesive area is reduced to maintain key sensitivity, then touch sensitivity is improved, but water accumulation increases
Solution Approach 1:
The label structure is segmented into adhesive regions and non-adhesive cavity regions. The cavities in functional areas maintain touch sensitivity by preventing adhesive interference, while simultaneously serving as water discharge channels to prevent water accumulation.
3Strength
If adhesive is applied in all areas for strong bonding, then adhesion strength is improved, but water discharge capability is reduced
Solution Approach 1:
Adhesive is applied selectively only in non-functional peripheral areas rather than uniformly across the entire label. This local application maintains sufficient adhesion strength for structural integrity while creating open cavities in functional areas that enable water discharge.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively discharges water from the control panel, preventing adhesive degradation, maintaining touch sensitivity and display clarity, while being cost-effective and reliable.
Implementation Method 1
Water guiding grooves are provided in the adhesive layer for communicating the cavities with the outside so as to discharge the accumulated water
Data Source
AI summary
The disclosure discloses a control panel and an outdoor device with the control panel, which can discharge accumulated water in the control panel to prevent water accumulation. A control panel for preventing water accumulation includes a display sheet which is transparent or translucent and used for covering and protecting a circuit board and/or component, an interface label having functional areas allowing a user to observe or operate the circuit board and/or component, and an adhesive layer connected between areas of the display sheet and the interface label except for the functional areas so as to adhere the display sheet and the interface label together. Cavities are formed between the functional areas of the interface label and corresponding locations of the display sheet so as to form a display window and/or key windows. The water guiding grooves are provided in the adhesive layer for communicating the cavities with the outside so as to discharge the accumulated water.
