Resonator Mounting Structure for Intake Ducts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resonator mounting structures for intake ducts in vehicles face challenges with air tightness and attachment workability, particularly due to interference between mounting pieces during screwing, which complicates the attachment process.
Innovation Solution
The proposed structure features duct-side mounting pieces with intervals and mounting surfaces opposing the turning direction of resonators, allowing easy turning and attachment without interference, along with strategically positioned and shared mounting pieces to enhance attachability and reduce component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an annular sealing member is disposed on the coupling portion and the resonator is screwed into the duct while being turned, then air tightness is held, but mutual interference between mounting pieces occurs causing deterioration of attachment workability
Solution Approach 1:
The duct-side mounting pieces are divided into multiple segments arranged at intervals in the peripheral direction, allowing the resonator to turn during attachment without interference between mounting pieces while maintaining sealing effectiveness
Solution Approach 2:
The mounting surfaces are positioned in the turning direction of the resonator, creating spatial separation that allows rotational movement during attachment while maintaining the sealing function of the mounting pieces
2Reliability
If multiple duct-side mounting pieces are provided for securing resonators, then attachment reliability is improved, but the number of components and complexity increases
Solution Approach 1:
Adjacent resonators share common duct-side mounting pieces, allowing the same mounting piece to serve multiple resonators and reducing the total component count while maintaining attachment reliability
Solution Approach 2:
Multiple resonator-side mounting pieces are consolidated to attach to a single shared duct-side mounting piece, merging multiple attachment functions into one component interface

AI summary
In a structure for mounting resonators to a duct, the duct including openings is provided with a plurality of duct-side mounting pieces, and the resonators formed separately from the duct and including communication ports coupled to the openings are provided with a plurality of resonator-side mounting pieces that are mounted to the duct-side mounting pieces. Coupling portions of the duct and the resonators are configured to ensure turning the resonators when the resonators are mounted to the duct. On the plurality of duct-side mounting pieces disposed with intervals in a peripheral direction of the coupling portions, mounting surfaces are formed to be opposed to turning directions of the resonators when mounting the resonators to the duct, the resonator-side mounting pieces being abutted against and mounted to the mounting surfaces. Accordingly, it is possible to turn the resonators when mounting them to the duct and improve attachment work.
