Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional working machines require separate operations for switching and locking the operation pattern switching valve, leading to complexity in the switching process.
Innovation Solution
An operation pattern switching device with a rotating operation member and an operation lever that integrates switching and locking functions, utilizing lock engagement parts and a spring mechanism to facilitate a series of actions for pattern switching and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate operations are used for switching and locking the operation pattern switching valve, then the valve can be reliably locked at switching positions, but the switching process becomes complex and requires multiple separate actions
Solution Approach 1:
The patent combines the switching operation and locking operation into a single integrated action. The operation lever simultaneously performs both functions: when moved to a switching position, it automatically locks into place via engagement with locking protrusions on the rotating spool. This eliminates the need for separate switching and locking actions, reducing operational complexity while maintaining reliable locking.
Solution Approach 2:
The system employs self-locking mechanism where the operation lever automatically engages with the locking protrusions on the rotating spool without requiring separate locking actions. The spring mechanism provides automatic return and engagement, making the locking process self-service and eliminating manual intervention for separate locking operations.
2Reliability
If multiple separate operations are required for pattern switching, then precise control can be achieved, but the time required for switching increases
Solution Approach 1:
The operation lever is designed with locking protrusions that are preliminarily positioned to engage with corresponding features on the rotating spool. As the lever is moved to a switching position, the locking engagement occurs automatically as part of the same motion, eliminating the need for separate locking actions and reducing switching time while maintaining precise control.
Solution Approach 2:
The patent merges the switching motion and locking motion into a single unified operation. The operation lever's movement simultaneously achieves both the switching of the operation pattern and the locking at the switching position, reducing the time required for pattern switching while maintaining precise control through the integrated mechanism.

Function Achieved in This Case
Simplifies the operability of switching and locking the operation pattern, improving the overall usability and reducing the complexity of the process.
Implementation Method 1
the operation lever is supported by the rotating operation member movably in a direction orthogonal to a shaft center of the rotating support shaft, and also moves in the moving direction to be thereby made engageable/removable with/from each of the lock engagement parts

AI summary
To improve operability of a switching operation and locking operation of an operation pattern switching valve for switching the operation pattern of controlling devices for actuator control valves. An operation pattern switching device has a rotating operation member that rotates around a shaft center of a rotating support shaft, and thereby performs a switching operation of the operation pattern switching valve; and an operation lever that is provided rotatably integrally with the rotating operation member and performs a rotating operation of the rotating operation member. The rotating support shaft is, at each pattern switching position of the operation pattern switching valve, in a circumferential direction, provided with a plurality of lock engagement parts each with which the operation lever engages. The operation lever moves in a direction orthogonal to the shaft center of the rotating support shaft, and be thereby made engageable/removable with/from each of the lock engagement parts.
