Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices that perform high-speed wired communications often generate noise that interferes with nearby wireless communications, such as LAN or Bluetooth, degrading their quality.
Innovation Solution
The connector includes electrically conductive protrusions at the distal end of the housing, which are connected to reference members to reduce noise emission by providing a path for noise to be grounded, thereby minimizing interference with wireless communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed wired communication is performed, then communication speed is improved, but noise emission increases and interferes with wireless communication
Solution Approach 1:
The patent extracts the noise emission problem by providing a dedicated grounding path through protrusions that extend from the housing. These protrusions capture and channel the noise generated by high-speed wired communication away from the wireless communication components, effectively separating the harmful noise path from the wireless signal path.
Solution Approach 2:
The protrusions act as an intermediary element between the wired communication interface and the housing. They provide a controlled path for noise to reach the housing, preventing direct noise emission into the wireless communication environment while maintaining the functionality of both wired and wireless communications.
2Object-generated harmful factors
If noise reduction measures are added to the connector, then noise emission is reduced, but device complexity increases
Solution Approach 1:
Instead of implementing noise reduction throughout the entire connector, the patent applies the noise reduction function locally through protrusions at specific locations on the housing. This localized approach reduces noise emission effectively while adding minimal structural complexity only where needed.
Solution Approach 2:
The protrusions are designed as simple extensions of the housing structure, utilizing the existing housing material and form factor. This approach adds noise reduction functionality without requiring separate complex components or assemblies, maintaining simplicity in the overall connector design.
