Electronic Picture Frame Assembly with Tool-Free Nested Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic frames are difficult to disassemble and assemble, which complicates maintenance and affects their usability in home decoration.
Innovation Solution
A frame design that includes a first frame, a back case, and a second frame, where the frames are engaged with each other using engagement protrusions and recesses, allowing for tool-free assembly and disassembly, and featuring a second frame that surrounds the first frame and back case for protection and decoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional fixation structures are used to assemble frame components, then connection strength is improved, but assembly and disassembly complexity increases
Solution Approach 1:
The frame is divided into multiple separable components (first frame, back case, second frame) that can be independently assembled and disassembled. Each component has standardized engagement structures that enable tool-free assembly while maintaining connection strength, resolving the contradiction between strong fixation and assembly simplicity.
Solution Approach 2:
The first frame and back case are nested within the second frame, creating a hierarchical assembly structure. The engagement protrusions and recesses allow inner components to be securely held by outer components, providing strong connection while enabling sequential assembly and disassembly without complex fastening mechanisms.
2Strength
If multiple frame layers are added for protection and decoration, then structural strength and aesthetics are improved, but device complexity increases
Solution Approach 1:
The frame structure employs three nested layers (first frame, back case, second frame) where each layer provides specific functions. The second frame surrounds and protects the inner components while the engagement structures simplify the overall assembly process, allowing multiple layers to be added without proportionally increasing complexity.
Solution Approach 2:
The second frame serves multiple functions simultaneously: it provides structural protection for inner components, offers aesthetic decoration by hiding fixation structures, and maintains assembly simplicity through standardized engagement structures. This multi-functionality resolves the contradiction between added complexity and improved performance.
3Ease of operation
If engagement protrusions and recesses are used for assembly, then ease of assembly is improved, but manufacturing precision requirements increase
Solution Approach 1:
The engagement structures are designed as separate, modular features on each frame component rather than integrated complex mechanisms. This segmentation allows for standardized manufacturing of engagement protrusions and recesses, reducing precision requirements while maintaining ease of assembly through simple matching geometries.
