Segmented Connecting Rod Assembly for Extended Top Dead Center
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional internal combustion engines lack efficient mechanisms to maintain the piston at upper dead center for extended periods, leading to suboptimal combustion efficiency, increased fuel consumption, and higher pollution levels due to tilting movements and inadequate alignment between the connecting rod and crankshaft.
Innovation Solution
A connecting rod design with two support points, one offset from the vertical axis and the other fixed, preventing tilting and maintaining the piston at upper dead center for longer durations, featuring a Y-shaped upper section and U-shaped lower section with semicircular angles, allowing for greater mechanical efficiency and optimized combustion stages.

Engineering Contradiction Analysis
1Productivity
If conventional connecting rod design is used, then the structure is simple, but the piston cannot be maintained at upper dead center for extended periods resulting in suboptimal combustion efficiency
Solution Approach 1:
The connecting rod is divided into multiple segments including a first connecting rod body, a second connecting rod body, and an intermediate connecting rod body. These segments are connected through pivoting supports that allow relative movement, enabling the piston to be maintained at upper dead center for extended periods while improving combustion efficiency without requiring a completely new rod structure.
Solution Approach 2:
The connecting rod incorporates dynamic elements including pivoting supports with bolts that allow the connecting rod bodies to pivot relative to each other. This dynamic structure enables the rod to adapt its configuration during the engine cycle, maintaining optimal piston positioning for combustion while managing the complexity through controlled degrees of freedom.
2Productivity
If the piston is maintained at upper dead center for longer time, then combustion efficiency improves, but the crankshaft must rotate at greater angles requiring more complex alignment mechanisms
Solution Approach 1:
The alignment mechanism is segmented into the crankshaft, a connecting rod assembly with multiple bodies, and pivoting supports. This segmentation allows each component to perform its specific function - the crankshaft rotates, the connecting rod bodies pivot relative to each other, and the pivoting supports facilitate controlled movement - achieving the required crankshaft rotation angles without a single complex alignment mechanism.
Solution Approach 2:
The intermediate connecting rod body acts as a mediator between the first and second connecting rod bodies. It includes a pivoting support with a bolt that allows controlled pivoting, serving as an intermediary element that enables the transmission and coordination of motion between the crankshaft and the piston while maintaining proper alignment during extended upper dead center positioning.
3Productivity
If conventional connecting rod design is used, then manufacturing is simple, but tilting movements occur causing increased fuel consumption and pollution
Solution Approach 1:
The connecting rod is manufactured as separate segments (first connecting rod body, second connecting rod body, intermediate connecting rod body) that are assembled through pivoting supports. This segmentation allows each part to be manufactured using standard processes, then assembled to create the tilt-prevention mechanism, improving fuel efficiency without requiring entirely new manufacturing capabilities.
Solution Approach 2:
The design merges the functions of multiple connecting rod components into a single integrated assembly. The first connecting rod body, second connecting rod body, intermediate connecting rod body, and pivoting supports work together as a unified structure that prevents piston tilting, reducing fuel consumption and pollution while maintaining manufacturability through modular assembly.
