Waterproof Assembly for Display Module Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with waterproof functions suffer from reduced light transmittance due to protective glass, affecting their display effectiveness, especially in medical and special scenarios where clarity is crucial.
Innovation Solution
A display module with a waterproof assembly comprising a deformation component, detector, and heater, where the controller heats the deformation component when water is detected within a set pressure range, preventing water ingress without obstructing the display region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective glass is used to seal the edge of the display screen for waterproofing, then the waterproof function is improved, but the light transmittance is reduced, resulting in poor display effect
Solution Approach 1:
The patent removes the protective glass from the display region while retaining waterproof sealing through an alternative structure: a waterproof assembly comprising a waterproof layer, deformation component, and sealing component that eliminates the need for obstructive glass coverage over the display screen
Solution Approach 2:
The front module frame is divided into a first portion covering the non-display region and a second portion covering the side surface, with the waterproof assembly specifically positioned in the gap between the display screen and the first portion, allowing selective waterproofing without compromising display visibility
2Reliability
If the heater continuously heats the deformation component to maintain waterproofing, then the water removal effect is improved, but the energy consumption increases
Solution Approach 1:
The controller controls the heater to operate intermittently rather than continuously, activating the heater only when water ingress is detected or suspected, thereby maintaining waterproof effectiveness while significantly reducing energy consumption
Solution Approach 2:
The system employs a detector to monitor the gap for water presence and provides feedback to the controller, which then activates the heater only when needed, creating a closed-loop control system that optimizes energy usage based on actual waterproofing requirements
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 maintains the display's clarity by removing water from the gap between the display screen and the front module frame, ensuring a waterproof effect without compromising the display's visibility or causing damage from excessive heating.
Implementation Method 1
the deformation component is configured to deform after absorbing water
Implementation Method 2
the heater is configured to heat the deformation component
Implementation Method 3
controller is configured to control the heater to heat the deformation component when the pressure detected by the detector is within a set pressure range
Implementation Method 4
the detector is configured to detect pressure received by the detector itself
