Safety Workbench Front Panel Cleaning Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety workbenches with adjustable front panes are difficult to clean completely without compromising the sealed work area, leading to contamination risks and compromised safety functions during the cleaning process.
Innovation Solution
The safety workbench features a front pane with an additional cleaning position that allows partial movement below the closed end position, enabling cleaning from above and below while maintaining the work area's protective functions, with mechanisms to prevent excessive lowering and ensure safety standards are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front pane is mounted to move only parallel to the front side of the housing, then the working opening remains sealed during operation, but the entire inside of the front pane cannot be cleaned
Solution Approach 1:
The front pane is designed with dynamic positioning capability, allowing it to move not only parallel to the front side but also downward below the closed end position. This dynamic adjustment enables the creation of a cleaning opening at the top edge while maintaining the sealed position during normal operation, resolving the contradiction between cleanability and sealing reliability.
2Ease of operation
If the front pane is opened upwards for cleaning, then the inside of the windscreen can be cleaned, but the work opening becomes completely open to the environment exposing the operator to contamination
Solution Approach 1:
The cleaning function is extracted from the normal operational position by creating a separate cleaning mode. The front pane can be positioned below the closed end position to create a dedicated cleaning opening at the top, allowing cleaning access without opening the bottom work area. This separates the cleaning operation from the work area exposure, eliminating contamination risk to the operator.
3Ease of operation
If the front pane is moved to create a cleaning opening at the top, then the entire pane becomes accessible for cleaning, but the opening cross-section increases potentially compromising air flow requirements
Solution Approach 1:
The front pane positioning system is designed to allow temporary dynamic extension below the closed end position specifically for cleaning operations. The cleaning opening is created at the top edge while the bottom remains sealed, and the system can return to the closed position immediately after cleaning. This dynamic capability enables complete cleaning access while maintaining air flow requirements during normal operation and limiting opening duration during cleaning.

AI summary
The invention relates to a safety workbench (1) with a work area (3) enclosed by a housing (2) and a housing front (4) which has a working opening (7) that can be closed by an adjustable front panel (5), wherein the front panel (5) has at least one additional cleaning position in which it is arranged at least partially below a closed end position in which the working opening (7) is completely covered, such that a cleaning opening (10) is formed between the upper edge of the panel and the housing (2). This additional cleaning position makes the front panel (5) easier and safer to clean compared to previously known safety workbenches.
