Chassis Member Design for Display Assembly Complexity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display apparatuses, such as plasma and liquid crystal televisions, require significant labor and have poor workability in assembling the chassis member components, leading to inefficiencies in manufacturing and increased man-hours due to the complexity of combining multiple frames into a framework structure.
Innovation Solution
A display apparatus design featuring a plate-like chassis member with stud pins and through-hole parts that securely mounts the circuit board, allowing for easier assembly by reducing the need for complex frame assembly and enabling universal compatibility with different circuit boards through adjustable stud pin positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple base metallic plates and combining metallic plates are used to form a chassis member, then the structural strength and reinforcement are improved, but the assembly complexity and labor requirements increase significantly
Solution Approach 1:
The patent combines multiple separate metallic plates (base plates and combining plates) into a single integrated chassis member with built-in reinforcement ribs. This merging eliminates the need for separate assembly steps while maintaining the structural strength provided by the reinforcement elements.
Solution Approach 2:
The chassis member is segmented into functional zones: base portions for mounting, reinforcement ribs for structural strength, and integrated forming portions that combine multiple functions into single structural elements, reducing assembly complexity while maintaining strength.
2Strength
If multiple separate frames are combined to form a framework structure, then the structural support is improved, but the assembly time and man-hours increase
Solution Approach 1:
The reinforcement ribs are integrated directly into the chassis member during manufacturing, combining the structural support function with the base plate function. This eliminates the need to assemble separate frames, significantly reducing assembly time while maintaining structural integrity.
Solution Approach 2:
The reinforcement structures are pre-formed and integrated into the chassis member before assembly with the display device. This preliminary action eliminates the need for complex on-site assembly of multiple frames, improving productivity.
3Strength
If a complex multi-plate chassis structure is used, then the structural reinforcement is improved, but the manufacturing cost and assembly labor increase
Solution Approach 1:
Multiple functional elements (base plate, reinforcement ribs, forming portions) are merged into a single chassis member that can be manufactured as one piece or pre-assembled unit. This reduces manufacturing steps and labor costs while maintaining structural reinforcement.

AI summary
According to one embodiment, a display apparatus includes a housing, a display panel contained in the housing, a longitudinal frame extending vertically along a back surface of the display panel and secured to the display panel, a circuit board electrically connected to the display panel, and a chassis member on which the circuit board is mounted. The chassis member is a plate-like member of a size greater than or equal to that of the circuit board, arranged between the longitudinal frame and an horizontal edge part of the display panel, supported by the longitudinal frame to be opposed to the back surface of the display panel, and provided with a stud pin to which the circuit board is secured.
