Cable Splitter Carriage With Resilient Arms for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-cable splitter assemblies in automotive systems often produce objectionable noise due to loose components within the assembly casing, resulting in buzz, squeak, and rattle.
Innovation Solution
A cable splitter assembly with a housing and a translating carriage featuring a body with recesses to seat cable terminal ends and resilient arms that contact the interior chamber, minimizing clearance and noise through the use of elastomeric bumpers and flexible arms to absorb vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional multi-cable splitter assemblies use loose components within the assembly casing, then the assembly allows component movement and adjustment, but this produces objectionable noise like buzz, squeak, and rattle
Solution Approach 1:
The patent combines the carriage body and resilient arms into a single integrated component. The resilient arms are formed as integral portions of the carriage body, eliminating separate loose components that would slide or rattle within the assembly casing, while still providing the necessary movement and adjustment functionality.
Solution Approach 2:
The patent uses resilient arms made of flexible material that can bend and deform elastically. These flexible arms provide the necessary movement capability while maintaining continuous contact with the housing, preventing the loose component movement that causes noise.
2Adaptability or versatility
If the carriage translates freely within the interior chamber, then the assembly allows cable adjustment, but this creates clearance and unwanted movement causing noise
Solution Approach 1:
The patent changes the physical state of the resilient arms from rigid to elastic, allowing them to deform under load. This enables the carriage to adjust position while maintaining stable, controlled contact with the housing through the elastic deformation of the arms, eliminating unwanted movement and clearance.
Solution Approach 2:
The patent transitions from a static rigid connection to a dynamic elastic connection. The resilient arms can flex and adapt to position changes while maintaining continuous contact, providing both adjustability and stability through controlled elastic deformation rather than free movement.
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
The solution effectively reduces noise and vibration by ensuring proper alignment and contact between the carriage and the housing, eliminating unwanted movement and noise issues within the assembly.
Implementation Method 1
a plurality of resilient arms integrally formed as one piece with the carriage body
Implementation Method 2
the use of elastomeric bumpers and flexible arms to absorb vibrations
