Line Noise Absorber Housing With Longitudinal Locking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for absorbing electrical noise on lines require significant space for folding or linear movement perpendicular to the lines, making them unsuitable for restricted spatial conditions, such as inside electronic devices.
Innovation Solution
A device with two housing parts that move into a closed state and lock together primarily through a relative movement parallel to the passage direction, minimizing the space required for installation and allowing for compact arrangement without the need for perpendicular space, using noise-absorbing materials like ferrite and a locking mechanism with latching means and sliding guides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional devices use folding movement or linear sliding movement perpendicular to the line, then the housing parts can be connected and locked, but significant space is required perpendicular to the passage direction
Solution Approach 1:
The patent inverts the conventional approach by changing the direction of relative movement from perpendicular to parallel with the passage direction. The housing parts move along the passage direction (longitudinally) instead of folding or sliding perpendicular to it, thereby eliminating the need for significant perpendicular space while maintaining reliable locking through the locking device engaged during this longitudinal movement.
Solution Approach 2:
The patent transitions from two-dimensional movement (folding or perpendicular sliding) to three-dimensional movement by utilizing the longitudinal dimension (parallel to passage direction) for the relative movement of housing parts. This dimensional change allows the device to achieve compact perpendicular profile while maintaining adequate space for locking mechanisms through the longitudinal displacement of housing parts.
2Ease of manufacture
If housing parts are moved perpendicular to the line for closing and locking, then the device can be assembled, but the arrangement space on electrical lines is increased
Solution Approach 1:
The patent inverts the conventional assembly approach by moving housing parts parallel to the passage direction (longitudinally) instead of perpendicular to it. This inversion maintains ease of manufacture through the locking device while dramatically reducing the perpendicular arrangement space required on electrical lines, allowing multiple devices to be installed in tighter configurations.
Solution Approach 2:
The patent changes the movement parameter from perpendicular displacement to longitudinal displacement parallel to the passage direction. This parameter change transforms the assembly process into a longitudinal insertion or sliding motion that maintains manufacturing simplicity while minimizing the perpendicular footprint and arrangement space occupied on electrical lines.
3Reliability
If folding movement about hinge is used to close and lock housing parts, then the device can be assembled, but space is required for folding movement
Solution Approach 1:
The patent replaces the folding movement mechanism with a longitudinal movement mechanism parallel to the passage direction. Instead of housing parts folding about a hinge (which requires perpendicular space), the parts move longitudinally along the passage direction to engage the locking device, thereby eliminating the need for folding space while maintaining reliable locking.
Solution Approach 2:
The patent substitutes the mechanical folding system (hinge-based rotation) with a linear longitudinal movement system. This mechanical substitution eliminates the arcuate folding path and associated space requirements, replacing it with a straightforward longitudinal displacement that engages the locking device while minimizing the volume required for the closing operation.
