Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses with high brightness suffer from insufficient heat dissipation due to restricted open ratios in their casings, which are designed to comply with safety standards, leading to inadequate airflow and potential overheating of electronic elements.
Innovation Solution
A display apparatus design featuring a casing with a higher open ratio, incorporating a dust-proof device with interlaced holes and a dust-proof element that allows increased airflow while preventing foreign matter ingress, ensuring compliance with safety standards and enhancing heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the open ratio of the casing is increased to improve heat dissipation, then the intake air amount increases, but the safety standard compliance deteriorates due to risk of foreign matter ingress and user safety hazards
Solution Approach 1:
The dust-proof device is divided into a body and a cover, both with holes that align to form airflow passages. This segmentation allows the casing to have effective openings for heat dissipation while the dust-proof element prevents foreign matter ingress, resolving the contradiction between open ratio and safety compliance.
Solution Approach 2:
A dust-proof element is introduced as an intermediary component between the body and cover holes. This element allows airflow to pass through for heat dissipation while blocking foreign matter and preventing finger insertion, thus maintaining both heat dissipation performance and safety standard compliance.
2Reliability
If the hole sizes are restricted to comply with safety standards, then user safety and dust-proof performance improve, but the intake air amount decreases leading to insufficient heat dissipation
Solution Approach 1:
The invention transitions from a single-plane hole design to a multi-dimensional airflow path. The body holes and cover holes are positioned at different planes, creating a three-dimensional airflow passage that increases the effective open ratio while maintaining safety compliance through the dust-proof element.
Solution Approach 2:
The airflow path is segmented into multiple sections (body holes, dust-proof element, cover holes) that work together to provide both safety compliance and sufficient airflow for heat dissipation, overcoming the limitation of restricted single-plane hole sizes.
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 design effectively improves airflow intake, enhancing heat dissipation and preventing dust entry, thus addressing the limitations of conventional designs by maintaining safety standards and improving cooling efficiency.
Implementation Method 1
fans are added inside the display apparatus to enhance the heat dissipation performance of the display apparatus, which is a common heat dissipation manner to perform the forced convection
Implementation Method 2
The dust-proof element is disposed between the body and the cover, and the airflow flows through the second opening, the second holes, the dust-proof element, the first holes, and the air inlet

AI summary
A display apparatus includes a casing, a display module, a cooling device, and a dust-proof device. The casing has first and second openings. The display module disposed in the casing has a display area exposed by the first opening and a non-display area corresponding to the second opening. The cooling device disposed at the non-display area in the casing has an air inlet corresponding to the second opening. The dust-proof device includes a body disposed at the non-display area in the casing, a cover disposed at the body, and a dust-proof element disposed therebetween. The body has first holes corresponding to the air inlet. The second opening exposes second holes of the cover. Each second hole overlaps at least one of the first holes. An airflow produced by the cooling device flows through the second opening, the second holes, the dust-proof element, the first holes, and the air inlet.
