Display Chassis Mounting Hole Cover for Dust-Free Wall Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses installed on walls often have exposed mounting holes, which affect their appearance and can allow foreign substances to enter, leading to damage and aesthetic issues.
Innovation Solution
A display apparatus design featuring a chassis with a cover that includes a concealing unit with a removing guide portion and a closing member to hide the mounting holes when not in use, preventing exposure and foreign substance entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display apparatus is installed on a wall using mounting holes, then the display apparatus can be fixed securely, but the mounting holes become exposed to the exterior affecting appearance and allowing foreign substance entry
Solution Approach 1:
The mounting structure is segmented into two functional parts: mounting holes for secure wall attachment and a separate concealing unit that covers the mounting holes. This segmentation allows the display apparatus to simultaneously achieve reliable wall mounting while preventing foreign substance entry through the covered mounting holes.
Solution Approach 2:
A concealing unit acts as an intermediary element between the mounting holes and the external environment. This concealing unit includes a cover body that fits over the mounting holes and a fastening member that secures the cover, thereby mediating between the need for exposed mounting holes and the need to prevent dust and foreign substance entry.
2Ease of operation
If mounting holes are exposed on the display apparatus, then fastening and unfastening is simple, but the appearance is degraded and damage risk increases
Solution Approach 1:
The concealing unit is pre-installed on the display apparatus in a concealed state, maintaining aesthetic appearance during normal use. When wall mounting is required, the concealing unit is temporarily removed to expose the mounting holes for fastening operations, then reinstalled to restore appearance after mounting is complete.
Solution Approach 2:
The concealing unit is designed with dynamic functionality, allowing it to transition between a concealed state (covering mounting holes for aesthetic purposes) and an exposed state (revealing mounting holes for installation). This dynamic design enables the system to adapt between appearance quality requirements and mounting operation requirements.
3Object-affected harmful factors
If a concealing unit is added to cover mounting holes, then appearance and protection improve, but device complexity increases
Solution Approach 1:
The concealing unit is designed as a multi-functional component that simultaneously provides appearance enhancement by covering mounting holes and protection against dust and foreign substance entry. This universal design consolidates multiple functions into a single integrated structure, reducing the need for separate protective components.
Solution Approach 2:
The concealing unit employs simple, easily manufactured components including a cover body and fastening member that can be produced cost-effectively. The design uses basic fastening mechanisms that are simple to assemble and disassemble, minimizing manufacturing complexity while achieving the desired protective and aesthetic functions.
