Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing graphite furnace locking device requires manual movement of the movable part in the unlocked state, posing safety risks due to high temperatures and electrical hazards.
Innovation Solution
A graphite furnace locking device with a latch bolt unit that provides a second elastic force to automatically move the movable part away from the stationary part upon unlocking, ensuring safe and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable part is manually moved away when unlocked, then the device can be operated, but operator safety is compromised due to high temperatures and electrical hazards
Solution Approach 1:
The locking device automatically moves the movable part away from the stationary part when unlocked, without requiring manual intervention. The elastic force generated by the spring mechanism self-propels the movable part to its initial position, making the system serve itself and eliminating the need for operator contact with hot or electrified components
Solution Approach 2:
The elastic force is pre-stored in the spring mechanism during the locking state. When unlocking occurs, this pre-stored energy is automatically released to move the movable part away, performing the safety-critical action before any potential harm can occur to the operator
2Object-affected harmful factors
If the movable part is automatically moved away using elastic force, then operator safety is improved, but the device complexity increases
Solution Approach 1:
The elastic force mechanism serves dual purposes: it provides the clamping force during locking and automatically propels the movable part away during unlocking. This self-service approach adds minimal structural complexity while achieving both safety and functional requirements
Solution Approach 2:
The same elastic force mechanism is combined to perform both the clamping function during locking and the automatic retraction function during unlocking. By merging these two functions into a single mechanism, the patent avoids adding separate complex systems while still achieving automatic safe retraction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device automatically springs the movable part away from the stationary part when unlocked, preventing operator injury and enhancing safety and operational convenience by eliminating the need for manual movement.
Implementation Method 1
a first elastic element, with one end connected with one end of the lock shaft that goes away and extends out from the stationary part, and the other end connected with the movable part; the latch bolt unit provides a first elastic force for the movable part towards the direction of the stationary part
Implementation Method 2
a second elastic element, a first protrusion portion being located between the first elastic element and the second elastic element, one end of the second elastic element being connected with the lock shaft, and the other end being connected with the stationary part; the latch bolt unit provides a second elastic force for the movable part in a direction away from the stationary part
