Hinge Wiring Layout for Noise Radiation Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with rotatable housings experience noise radiation issues due to power supply wiring configurations, particularly when these wirings are led through multiple hinge sections, leading to electromagnetic interference (EMI) and increased noise radiation.
Innovation Solution
The electronic apparatus is designed with power supply wirings led through a single hinge section, allowing the magnetic fluxes to cancel each other out, thereby reducing noise radiation and improving EMI characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power supply wirings are led through multiple hinge sections, then the rotatable connection between housings is achieved, but noise radiation and electromagnetic interference increase
Solution Approach 1:
The patent merges multiple power supply wirings into a single hinge section passage. Instead of routing wirings through separate hinge sections, the invention consolidates them to pass through one common hinge section, which allows the magnetic fluxes to cancel each other out and reduces noise radiation and electromagnetic interference.
2Object-generated harmful factors
If power supply wirings are led through a single hinge section, then magnetic fluxes cancel each other reducing noise radiation, but wiring configuration becomes more complex
Solution Approach 1:
The patent converts the potentially harmful magnetic fluxes generated by power supply wirings into a beneficial effect. By routing multiple wirings through a single hinge section, the magnetic fluxes from adjacent wirings cancel each other out, transforming the harmful electromagnetic interference into a noise-reducing mechanism.
