V-Engine Throttle Body Coupling for Rigid Low-Weight Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing throttle apparatus for V-type engines, which connects throttle bodies using connection plates, faces issues with increased weight, occupied space, and manufacturing cost due to the use of thick steel plates and complex assembly processes.
Innovation Solution
The throttle apparatus integrates coupling portions with the throttle bodies, allowing for easy assembly and improved rigidity by using fastening members to connect the throttle bodies without additional weight or space, and simplifies the assembly process by using a motor unit and interlocking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If connection plates are provided on both sides of throttle bodies to firmly connect them, then assembling rigidity is improved, but weight increases
Solution Approach 1:
The coupling portions are integrally formed with the throttle bodies as a single piece, eliminating the need for separate connection plates. This merging of components reduces the total number of parts and material usage, thereby decreasing weight while maintaining the connection function through the integrated structure.
2Stability of the object's composition
If connection plates are provided on both sides of throttle bodies to firmly connect them, then assembling rigidity is improved, but occupied space increases
Solution Approach 1:
By integrating the coupling portions directly into the throttle bodies, the design eliminates the additional space that would be required for separate connection plates and their mounting structures. This integration reduces the overall outer dimension of the throttle apparatus in the axial direction.
3Stability of the object's composition
If connection plates are used to connect throttle bodies, then assembling rigidity is improved, but manufacturing cost increases
Solution Approach 1:
The integral formation of coupling portions with throttle bodies reduces the number of separate components that need to be manufactured, stored, and assembled. This integration simplifies the manufacturing process, reduces assembly steps, and lowers overall manufacturing cost while maintaining connection rigidity.
Solution Approach 2:
The design extracts and eliminates the connection plates from the system entirely, replacing them with integrated coupling portions. This removal of unnecessary components reduces material costs, manufacturing complexity, and assembly operations.
4Strength
If connection plates are used to connect throttle bodies with multiple fastening positions, then connection strength is improved, but device complexity increases
Solution Approach 1:
The coupling portions integrated with the throttle bodies incorporate the fastening features directly into the main structure, eliminating the need for separate connection plates with multiple fastening positions. This integration reduces structural complexity while maintaining connection strength through the unified design.
