Flat Panel Display Speaker Mounting via Integrated Securing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and removal of speakers in flat panel display subassemblies are inconvenient due to the need for screws, which increases manufacturing costs and relies on manual labor.
Innovation Solution
A securing structure is integrally formed on the back cover or front frame of the flat panel display subassembly, featuring securing columns with parallel ridges that correspond to through holes in the speaker ears, allowing the speakers to be secured and removed without screws by aligning and pressing them into place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to secure speakers, then the speakers are firmly fixed, but the assembly and removal process becomes inconvenient and increases manufacturing cost
Solution Approach 1:
The patent removes screws from the speaker mounting system entirely. Instead of using threaded fasteners, the invention uses integrated securing structures (protrusions on the back cover engaging with recesses in the speaker housing) that provide firm fixation without requiring screw insertion or thread engagement, thereby eliminating the manual labor and complexity associated with screw assembly
Solution Approach 2:
The securing structures are integrally formed as part of the back cover assembly rather than being separate components. The protrusions extend directly from the back cover and engage with corresponding recesses in the speaker housing, merging the fastening function into the structural design of the back cover itself, which eliminates the need for separate screw fasteners and simplifies the assembly process
2Reliability
If screws are used to secure speakers, then the speakers are firmly fixed, but the manufacturing cost increases due to manual labor
Solution Approach 1:
The patent eliminates screws and thread engagement operations from the manufacturing process. The integrated securing structures allow speakers to be mounted through simple alignment and pressing operations, removing the need for costly manual screw installation and reducing manufacturing complexity
Solution Approach 2:
The securing structures are designed to be self-aligning and self-securing. The protrusions on the back cover automatically engage with the recesses in the speaker housing when the speaker is positioned correctly, eliminating the need for manual thread engagement operations and reducing labor costs
3Reliability
If screws are used to secure speakers, then the speakers are firmly fixed, but the assembly process becomes complex
Solution Approach 1:
The patent removes the complex thread engagement mechanism and separate screw components from the assembly process. The integrated securing structures reduce the assembly process to simple alignment and pressing operations, significantly reducing the number of steps and components involved
Solution Approach 2:
The securing function is merged into the back cover structure itself through integrally formed protrusions. This eliminates the need for separate screw fasteners and reduces the assembly process to a single operation of positioning and pressing the speaker into place, rather than multiple steps of aligning and fastening with screws

AI summary
An exemplary flat panel display subassembly (1) includes a front frame (10), a back cover (12), and a speaker (14). The back cover is adjacent to the front frame. The speaker is adjacent to one of the front frame and the back cover, and defines a through hole (146) therein. One of the front frame and the back cover includes a securing structure (129) engaged in the through hole.
