Display Front Chassis Hook Assembly Without Exposed Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of display apparatuses using screws for the front chassis increases costs, time, and negatively impacts the aesthetic appearance by exposing screws externally.
Innovation Solution
A hook-assembling method is employed for the front chassis to connect with the middle frame, eliminating the need for screws, thereby reducing assembly costs and time while improving aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to assemble the front chassis to the middle frame, then the assembly structure is simple and reliable, but the assembly cost increases, assembly time increases, and screws are exposed externally affecting aesthetics
Solution Approach 1:
The patent extracts the harmful element (screws) from the assembly system by replacing the screw-based fastening mechanism with a hook-based snap-fit mechanism. The front chassis includes hooks that engage with corresponding structures on the middle frame, eliminating the need for exposed screws while maintaining assembly reliability and improving aesthetics.
2Strength
If screws are used to assemble the front chassis, then the connection is strong and reliable, but the assembly process becomes time-consuming and costly
Solution Approach 1:
The patent applies preliminary action by pre-forming the hooks on the front chassis during the molding process, so that the fastening elements are already in place before assembly. This eliminates the need for separate screw installation steps, reducing assembly time while maintaining connection strength through the hook engagement mechanism.
3Stability of the object's composition
If screws are used for assembly, then the structural connection is secure, but the aesthetic appearance deteriorates due to exposed screws
Solution Approach 1:
The patent removes the visually problematic screws from the external view by replacing them with hidden hook mechanisms. The hooks are positioned such that they engage with the middle frame from the interior or side, keeping the front chassis surface clean and aesthetic while maintaining structural stability through the hook engagement.
4Ease of manufacture
If a hook-assembling method is used to connect the front chassis to the middle frame, then assembly cost and time are reduced, and aesthetics are improved, but the assembly precision requirement increases
Solution Approach 1:
The patent replaces the mechanical screw-fastening system with a snap-fit hook mechanism that relies on elastic deformation and geometric interlocking. The hooks are designed with specific dimensions and elasticity to engage with corresponding features on the middle frame, providing self-aligning and self-locking characteristics that reduce assembly precision requirements compared to traditional screw mechanisms.
Data Source
AI summary
A display apparatus includes a rear chassis, a light source installed on the rear chassis and configured to emit light, a middle frame fastened to a front side of the rear chassis, a diffuser plate fixed to the middle frame on a front side of the light source and configured to diffuse the light emitted from the light source, a panel disposed on a front side of the diffuser plate, and a front chassis configured to cover an edge of the panel, wherein the front chassis includes a plurality of frame assembly portions formed on a first surface of the front chassis configured to be detachably assembled to the middle frame, and the plurality of frame assembly portions are assembled in a direction perpendicular to the middle frame.
