Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diesel engine valve plate locking mechanisms require high initial installation accuracy, are costly to disassemble and replace, and suffer from wear-related failures, complicating maintenance and posing security risks due to direct reset by torsion springs.
Innovation Solution
An electric locking mechanism for valve plates featuring a lock rod, lock head, elastic return mechanism, and motor-driven seat body, with detachable components and adjustable sharp corners, allowing for reduced installation precision and easy maintenance through external control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock rod and lock head are directly connected with high precision engagement, then the locking reliability is improved, but the installation accuracy requirement increases and maintenance complexity increases
Solution Approach 1:
The lock rod is divided into two detachable parts: the base rod part and the base block part. The base block part with the external convex corner can be detached and replaced independently, allowing for easier installation and maintenance while maintaining reliable locking through the sharp corner-step engagement mechanism.
Solution Approach 2:
The lock rod design allows for dynamic adjustment and replacement of the base block part. The detachable connection enables the system to adapt to wear and damage by replacing only the necessary component, rather than requiring high precision installation of a fixed rigid structure.
2Ease of operation
If the lock rod is reset directly by torsion spring, then the reset function is achieved, but the maintenance convenience deteriorates and security risks increase
Solution Approach 1:
The adjusting terminal acts as an intermediary mechanism between the external operator and the lock rod. It provides external control over the lock rod's movement, allowing maintenance personnel to easily manipulate and inspect the lock rod without direct exposure to internal torsion spring mechanisms, thereby improving both ease of operation and maintenance safety.
3Device complexity
If the lock rod and lock head are designed as integrated components, then the structural simplicity is improved, but the replacement cost and material waste increase
Solution Approach 1:
The lock rod is segmented into the base rod part and the base block part, where only the base block part needs to be replaced when worn or damaged. This segmentation prevents the need to replace the entire lock rod assembly, reducing material waste and replacement costs while maintaining structural simplicity through the straightforward detachable connection.
4Measurement precision
If the lock rod requires high installation accuracy, then the locking precision is improved, but the ease of installation deteriorates
Solution Approach 1:
The external convex corner on the base block part and the corresponding step on the lock head create an asymmetric engagement mechanism. This asymmetric design provides self-alignment during installation, guiding the components into the correct position naturally and reducing the need for high precision installation while ensuring accurate locking engagement.
