Display Support Member Bent Leg Assembly Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device assembly methods face challenges with poor workability, damage to support members, and increased protruding height of leg portions, leading to issues with alignment and fixation of support members on the reflection plate.
Innovation Solution
The display device incorporates a support member with a bent leg portion that passes through holes in the reflection plate and frame member, featuring a second hole for protrusion fitting, which reduces damage and protruding height, and improves alignment and fixation by sliding the support member along parallel sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pawl structure is used to fix the support member, then fixation reliability is improved, but the complexity of assembly and risk of damage increases
Solution Approach 1:
The invention extracts and eliminates the pawl structure from the support member, replacing it with a simpler insertion method through aligned holes in the reflection plate and frame member. This removes the complex locking mechanism while maintaining adequate fixation through the insertion fit alone.
Solution Approach 2:
The support member is segmented into distinct functional portions: an insertion portion that passes through holes, a standing support portion that provides structural support, and an optical member support portion. This segmentation allows each part to perform its specific function without requiring complex interlocking mechanisms like pawls.
2Adaptability or versatility
If the leg portion protrudes高度 to allow circuit board attachment, then functionality is improved, but the overall device height increases
Solution Approach 1:
The invention relocates the circuit board attachment function from the vertical dimension (protruding leg portion) to the horizontal dimension (surface of the standing support portion). The circuit board is attached to the surface of the standing support portion rather than to a protruding leg, thereby maintaining attachment capability while reducing overall device height.
3Reliability
If holes are provided in both reflection plate and frame member for support member insertion, then fixation is improved, but alignment difficulty increases
Solution Approach 1:
The invention introduces asymmetric positioning features: the hole in the reflection plate is positioned offset from the center of the support member's insertion portion, while the hole in the frame member is positioned to create a specific insertion path. This asymmetric arrangement provides natural alignment guidance during assembly, reducing alignment difficulty while maintaining fixation stability.

AI summary
A display device includes: a reflection plate; plural light sources disposed above the reflection plate; an optical member disposed above the plural light sources; a support member disposed standing on a bottom surface of the reflection plate; a frame member that houses the reflection plate and the light sources; and a display panel disposed above the optical member. The support member includes: a standing support portion that is disposed standing on and supports the reflection plate; an optical member support portion that supports the optical member; and a leg portion that protrudes downward of the reflection plate and the frame member and is bent in a direction along the standing support member.
