Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with narrow frame designs face space constraints due to screw-fastened antenna connections to metal frames, requiring additional structures like screw seats in the frame border area.
Innovation Solution
A conductive elastic component with a fixing portion and bent extension portion is used to connect the antenna to the metal frame, eliminating the need for additional structures in the frame border area, allowing for secure fixation and efficient space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to connect the antenna to the metal frame, then the grounding effect is achieved, but additional structures (screw seats) are required in the frame border area, consuming limited space
Solution Approach 1:
The patent combines the grounding function and the connection function into a single conductive elastic component. The component integrates the electrical connection capability (for grounding) with the mechanical fastening capability (replacing screws and screw seats), thereby eliminating the need for separate screw seats in the frame border area and saving space while maintaining the grounding effect
Solution Approach 2:
The conductive elastic component serves multiple functions simultaneously: it provides electrical connection for grounding, acts as a mechanical fastener to secure the antenna, and eliminates the need for additional fixing structures. This multi-functional design resolves the space constraint by consolidating multiple functions into a single component
2Reliability
If screw seats are added to the frame border area for antenna fixation, then secure connection is achieved, but the device complexity increases due to additional structures
Solution Approach 1:
The conductive elastic component merges the electrical connection function and mechanical fastening function into one integrated component. This eliminates the need for separate screw seats and screws, thereby reducing device complexity while maintaining secure connection between the antenna and metal frame
Solution Approach 2:
The invention extracts and eliminates the unnecessary screw seat structures from the frame border area by using the conductive elastic component that performs both grounding and fastening functions independently, thereby simplifying the overall frame structure
3Reliability
If conventional screw fastening is used, then the antenna is securely connected, but the current path is longer and Z-axis waviness occurs during assembly
Solution Approach 1:
The conductive elastic component uses an elastic material that can deform and conform to the surfaces it connects. This flexibility allows the component to maintain intimate contact between the antenna and metal frame, eliminating Z-axis waviness during assembly while providing a shorter, more direct current path compared to rigid screw fastening
Solution Approach 2:
The elastic component changes the physical state from rigid (screws) to flexible, allowing it to adapt to surface variations and maintain optimal contact. This parameter change eliminates harmful Z-axis waviness and creates a shorter current path while maintaining connection stability

AI summary
A conductive elastic component includes a fixing portion and a bent extension portion. The fixing portion includes a first section, a second section, and a third section that are bent and connected in sequence, and the first section corresponds to the third section. The bent extension portion extends from the fixing portion and includes a fourth section, a fifth section, and a sixth section that are bent and connected in sequence. The fourth section is connected to the second section, and the sixth section bends towards the fixing portion, such that the sixth section is located between the fourth section and the fifth section. The sixth section is adapted to abut the fourth section or the second section.
