Adjustable Camshaft Switch Device with Space Cam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching devices with camshafts face challenges in easy assembly, adjustability, and operational reliability due to complex designs and difficult component assembly, especially in setting and adjusting switching points without opening the housing.
Innovation Solution
A switching device with a space cam and a displaceable switching element parallel to the camshaft axis, allowing for adjustable switching points via a carriage system and external adjustment means, such as adjustment shafts, enabling setting and re-adjustment without opening the housing, and featuring a latching mechanism for easy locking and removal of the carriage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional camshafts with fixed switching points are used, then the device structure is simple, but the switching points cannot be adjusted during operation
Solution Approach 1:
The camshaft is divided into individual cams that can be independently adjusted along the camshaft axis. Each cam can be positioned separately to set different switching points, allowing flexible adjustment without redesigning the entire camshaft structure.
Solution Approach 2:
The switching device transitions from a static camshaft with fixed switching points to a dynamic system where cams can be adjusted during operation. The adjustment mechanism allows the cam positions to be changed while the device is running, enabling adaptive control of switching points.
2Adaptability or versatility
If complex adjustment mechanisms are used to enable switching point adjustment, then the switching points become adjustable, but the assembly becomes difficult and time-consuming
Solution Approach 1:
The camshaft is divided into individual cams that can be independently adjusted along the camshaft axis. Each cam can be positioned separately to set different switching points, allowing flexible adjustment without redesigning the entire camshaft structure.
Solution Approach 2:
The switching points are adjusted by changing the axial position parameter of each cam on the camshaft. This simple parameter change allows flexible adjustment of switching points without complex mechanical modifications or additional adjustment mechanisms.
3Adaptability or versatility
If multiple components are used to achieve switching point adjustment, then the adjustability is improved, but the number of components increases and assembly difficulty increases
Solution Approach 1:
The switching points are adjusted by changing the axial position parameter of each cam on the camshaft. This simple parameter change allows flexible adjustment of switching points without complex mechanical modifications or additional adjustment mechanisms.
Solution Approach 2:
The adjustment functionality is integrated directly into the camshaft structure itself, with cams that can be positioned along the axis. This merging of adjustment capability into the existing structure avoids adding separate adjustment mechanisms and reduces the total number of components.
4Ease of operation
If fixed cam positions are used, then the device structure is simple, but the switching points cannot be adjusted without opening the housing
Solution Approach 1:
The switching device transitions from a static camshaft with fixed switching points to a dynamic system where cams can be adjusted during operation. The adjustment mechanism allows the cam positions to be changed while the device is running, enabling adaptive control of switching points.
Solution Approach 2:
The switching points are adjusted by changing the axial position parameter of each cam on the camshaft. This simple parameter change allows flexible adjustment of switching points without complex mechanical modifications or additional adjustment mechanisms.

AI summary
The invention relates to a switch device with at least one switch element (7) actuated by a cam of a camshaft (3). The switch device is distinguished in that the cam is formed as a three-dimensional cam (4) and in that the at least one switch element (7) is arranged so as to be displaceable substantially parallel to an axis of the camshaft (3) in order to adjust a switch point.
