Embedding Press Sliding Closure for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embedding presses face challenges in operator ergonomics and workplace safety, particularly during hot embedding processes, and there is a need for a more efficient and cost-effective solution that can be retrofitted to existing systems.
Innovation Solution
The embedding press incorporates a sliding closure mechanism with a locking lever and upper piston that allows for one-handed operation, featuring a cam or eccentric component for easy closure and a compressible element for secure positioning, along with a suction device for vapor and dust extraction, and a modular system for centralized control and power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional embedding press closure mechanism is used, then the press can be closed securely, but the operation requires two hands and reduces ergonomics and work safety
Solution Approach 1:
The locking lever is designed to automatically engage with the locking surface when the sliding carriage reaches the closed position, allowing the system to secure itself without requiring a second hand. The spring element provides automatic resetting of the locking mechanism after each operation cycle.
Solution Approach 2:
The manual two-handed mechanical operation is replaced by a spring-loaded assisted closing mechanism where the spring element stores energy during opening and releases it during closing, reducing the manual effort required and enabling one-handed operation while maintaining secure closure.
2Ease of operation
If the sliding carriage is designed for easy displacement, then operator ergonomics improve, but the mechanism complexity increases
Solution Approach 1:
The spring element acts as a counterbalancing force that offsets the weight and friction resistance of the sliding carriage, making it easier to displace the carriage along the slide support without requiring complex motorized or hydraulic systems.
3Reliability
If existing embedding presses are retrofitted with new closure mechanisms, then operational safety improves, but the cost and complexity of modification increases
Solution Approach 1:
The closure mechanism is divided into modular components (sliding carriage, locking lever, spring element, guide rails) that can be manufactured separately and installed incrementally on existing presses, reducing retrofit complexity and cost while maintaining safety improvements.

AI summary
The invention relates to a mounting press for mounting a sample, comprising a mounting cylinder for receiving the sample, with a main cylinder axis and a cylinder opening, the main cylinder axis extending inside the mounting cylinder and passing through the cylinder opening, a sliding closure with a sliding carriage, an upper piston and a closing lever that cooperates with the upper piston, the sliding carriage being embodied such that it can move in a direction transverse to the main cylinder axis, particularly by means of the closing lever, and the upper piston can be guided on or into the cylinder opening of the mounting cylinder in a position of use of the sliding carriage. The closing lever has at least one open position and a closed position and can switch from the open position to the closed position, the closing lever cooperating with the upper piston in such a way that the upper piston closes the cylinder opening by guiding the closing lever from the open position to the closed position, when the sliding carriage is in the position of use.
