Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded fasteners are used to secure lenses in assembly holes, then the connection between lenses and frame is stable, but tools are required for assembly and disassembly making the process inconvenient
Solution Approach 1:
The frame is divided into upper and lower frame portions that can be separated from each other. The lens assembly holes are formed between these two portions, allowing the lens to be accessed and removed when the frame is disassembled. This segmentation enables tool-free lens replacement while maintaining secure attachment during wear.
Solution Approach 2:
The connection between upper and lower frame portions transitions from a static permanently fixed state to a dynamic state where they can be easily connected and disconnected. The outer edges of the frame portions are designed to allow simple connection and separation, enabling users to assemble and disassemble the lens holder without tools.
2Reliability
If threaded fasteners are used to fix lenses, then secure holding is achieved, but assembly and disassembly require tools and time
Solution Approach 1:
The frame structure is segmented into separable upper and lower portions with lens assembly holes positioned between them. This allows the lens to be quickly accessed by separating the frame portions, eliminating the time-consuming process of using threaded fasteners for lens installation and removal.
Solution Approach 2:
The frame connection changes from a static threaded fastener system requiring multiple turns to a dynamic system where upper and lower frame portions can be quickly connected and disconnected by their outer edges, dramatically reducing assembly and disassembly time.
3Reliability
If lenses are held in assembly holes with threaded fasteners, then stable connection is achieved, but tool-free operation is not possible
Solution Approach 1:
The frame is segmented into upper and lower portions that can be easily separated, providing direct access to the lens assembly holes. This segmentation enables tool-free lens replacement by allowing users to simply separate the frame portions, insert or remove the lens, and reconnect the portions.
Solution Approach 2:
The connection system transitions from a static threaded fastener mechanism requiring external tools to a dynamic system where the outer edges of frame portions can be manually connected and disconnected, achieving tool-free operation while maintaining connection stability during normal use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easier, quicker, and more convenient lens assembly and disassembly without tools, ensuring secure lens positioning and preventing damage to the frame.
Implementation Method 1
The fixing member includes an elastic mounting portion projecting from the fixing member and corresponding to the through hole and the mounting fixing hole, and an elastic positioning piece which is extending and projecting from the fixing member
Data Source
AI summary
A pair of full frame glasses is revealed. A through hole and a mounting fixing hole are penetrating an upper frame portion and a lower frame portion of a frame respectively while an upper mounting wall is formed behind the through hole and a lower mounting wall is formed behind the mounting fixing hole. A fixing member includes an elastic positioning piece and an elastic mounting portion capable of being inserted through the through hole and the mounting fixing hole. An upper mounting projection corresponding to a lower edge of the upper mounting wall and a lower mounting projection corresponding to a lower edge of the lower mounting wall are projecting from the elastic positioning piece. Thereby the upper and lower frame portions are connected securely by the fixing member. During assembly and disassembly processes, no tool is required so that the glasses are more convenient to use.
