Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixating a coil assembly to a valve housing in actively controlled dampers often result in improper mounting, leading to deformations, corrosion, and vibrations, which can cause malfunctions and noise.
Innovation Solution
A redesign of the coil assembly incorporating a pre-tensioning locking member and guiding projections to ensure accurate alignment and fixation, using an intermediate member to guide the resilient locking member into a pre-tensioned state, with clear feedback on correct assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking ring is used to fixate the coil assembly to the valve housing, then the assembly can be secured, but improper mounting occurs leading to deformations, corrosion, and vibrations
Solution Approach 1:
The resilient locking member is pre-tensioned by the intermediate member before final assembly, ensuring correct positioning and tension is established in advance. This preliminary action prevents improper mounting during the final assembly process, as the locking member is already in the correct state before being received by the locking aperture.
Solution Approach 2:
The intermediate member acts as a mediator between the coil housing and valve housing during assembly. It guides the resilient locking member into the correct pre-tensioned state and ensures proper alignment, eliminating the need for blind mounting and preventing deformations and vibrations.
2Productivity
If the coil assembly is blindly mounted into the valve housing, then assembly can proceed without precise alignment, but deformations and vibrations occur
Solution Approach 1:
The intermediate member serves as a guiding intermediary that provides precise alignment during assembly. Its guiding projection ensures the resilient locking member is correctly positioned as the coil housing moves relative to the valve housing, enabling both fast and precise assembly without blind mounting.
Solution Approach 2:
The system provides mechanical feedback through the guiding projection and locking aperture interaction. As the coil housing moves into the final assembled position, the guiding projection ensures the resilient locking member is correctly positioned and tensioned, providing immediate feedback on proper assembly without requiring external inspection.
3Device complexity
If the resilient locking member is not pre-tensioned, then assembly is simpler, but improper mounting and malfunctions occur
Solution Approach 1:
The intermediate member pre-tensions the resilient locking member before final assembly by moving the coil housing relative to it. This preliminary action ensures the locking member is correctly tensioned and positioned in advance, preventing improper mounting and malfunctions while maintaining assembly correctness.
Solution Approach 2:
The intermediate member automatically pre-tensions the resilient locking member through the relative movement of the coil housing during assembly. This self-service mechanism ensures correct assembly without requiring additional manual intervention or complex external tensioning devices, balancing simplicity with reliability.
