Solution Overview
Problem
Precision scales in safety work cabins are difficult to clean after weighing toxic substances, leading to potential cross-contamination and increased cleaning effort, which complicates product and personal protection.
Innovation Solution
An integrated work cabin with a precision scale design where only essential components are within the work space, with a partition wall and controlled air flow to prevent substance leakage, allowing for easy cleaning and improved protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the precision scale is placed inside the work cabin, then the weighing function is integrated and accessible, but the cleaning effort increases and cross-contamination risk rises due to complex components
Solution Approach 1:
The precision scale is divided into two segments: the load receptor (weighing pan) remains inside the work cabin for accessibility, while the weighing system (electronic components, power supply, cables) is separated and placed outside in a separate housing. This segmentation allows the work cabin to be easily cleaned without disassembling complex electronic components, resolving the contradiction between operational accessibility and cleaning ease.
2Ease of manufacture
If the precision scale components are arranged outside the work space, then cleaning becomes easier, but the integration and functional coordination between work cabin and scale deteriorates
Solution Approach 1:
A coupling element acts as an intermediary, connecting the load receptor inside the work cabin to the weighing system outside through a partition wall. This coupling element maintains functional coordination between the separated components while allowing the work cabin to be easily cleaned, thus resolving the contradiction between cleaning ease and functional integration.
3Object-affected harmful factors
If a partition wall is added to separate the weighing system, then substance leakage is prevented, but the structural complexity and device integration increase
Solution Approach 1:
The partition wall is merged with the rear wall of the work cabin, creating a smooth-surfaced structure that prevents substance leakage while maintaining easy cleanability. The coupling element passes through this integrated partition wall, allowing functional connection without compromising the protective barrier. This merging approach prevents substance leakage while minimizing structural complexity.
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
Facilitates efficient cleaning of the work cabin, enhances personal and product protection by minimizing substance transfer and optimizing component coordination, while maintaining accurate weighing processes.
Implementation Method 1
This ensures that all particles or aerosols of the substances that get into the ambient air during handling are sucked off in a controlled manner
Implementation Method 2
a suction device (200) is integrated into the work cabin (22)
Implementation Method 3
a pressure difference can be established between the work space of the work cabin and a space in which the weighing system is arranged. With this pressure difference, if the pressure inside the work cabin is lower than in the space in which the weighing system is arranged, an air flow can be brought about from the space of the weighing system towards the work space of the work cabin
