Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal combustion engine systems face challenges in efficiently supporting camshafts, fuel injectors, and wire harnesses, requiring complex and heavy cylinder heads that complicate maintenance and increase manufacturing costs.
Innovation Solution
A camshaft carrier structure that separates and supports these components from the cylinder head, using lighter materials like aluminum alloys, reducing the need for additional supporting hardware and allowing for modular engine designs with simplified servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If camshafts, fuel injectors, and wire harnesses are integrated into the cylinder head, then structural strength is maintained, but device complexity and weight increase
Solution Approach 1:
The invention separates the camshaft support function from the cylinder head by introducing a camshaft carrier. The carrier is a standalone component that houses the camshaft and provides mounting points for fuel injectors and wire harnesses, dividing the integrated system into modular segments that can be manufactured and serviced independently.
Solution Approach 2:
The camshaft carrier extracts the camshaft support functionality from the cylinder head structure. By removing this function from the main cylinder head body, the design reduces overall complexity while maintaining structural integrity through the dedicated carrier component.
2Stability of the object's composition
If traditional integrated design is used, then structural integrity is maintained, but manufacturing cost and machining time increase
Solution Approach 1:
The camshaft carrier serves as a separate manufacturable unit that can be produced independently from the cylinder head. This segmentation allows for specialized manufacturing processes, reduced machining time on the main cylinder head, and lower overall production costs while preserving structural integrity through proper coupling.
Solution Approach 2:
The camshaft carrier acts as an intermediary component between the cylinder head and the camshaft assembly. This mediator provides a dedicated interface that simplifies manufacturing by concentrating complex features in a separate, optimized component rather than requiring complex machining of the cylinder head itself.
3Strength
If components are integrated into the cylinder head, then structural strength is maintained, but ease of repair deteriorates due to complex disassembly
Solution Approach 1:
The modular camshaft carrier design enables independent removal and replacement of the carrier assembly from the cylinder head. This segmentation allows mechanics to service camshaft, fuel injector, and wire harness components without disassembling the entire cylinder head, significantly improving ease of repair while maintaining structural strength through the coupling interface.

AI summary
The application relates to a camshaft carrier for supporting a camshaft, an engine system, and a method of assembly. An engine system includes a cylinder block, a cylinder head, a camshaft carrier, a camshaft, and a fuel injector assembly. The cylinder head is coupled to the cylinder block and defines at least one of an inlet passage or an exhaust passage therein. The camshaft carrier is coupled to the cylinder head and the camshaft is coupled to the camshaft carrier. The fuel injector assembly is coupled to the camshaft carrier and extends through a carrier sidewall of the camshaft carrier.
