Food Counter Dishwasher Layout for Hygienic Reusable Container Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Previous counter systems in catering and retail trade fail to efficiently transfer partially unpackaged foodstuffs while maintaining environmental sustainability and hygiene regulations, often relying on disposable plasticware that poses ecological and health risks.
Innovation Solution
A counter system with an integrated dishwasher that segregates customer and staff regions, allowing customers to deposit and staff to collect cleaned reusable containers, minimizing contamination risks and eliminating the need for disposable crockery by ensuring rapid and hygienic cleaning within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable crockery is used to transfer foodstuffs, then hygiene and convenience are improved, but environmental pollution and plastic waste increase
Solution Approach 1:
The patent applies disposable crockery made from oxo-degradable plastic as a short-living object that can be discarded after single use, eliminating the need for washing and reuse while reducing environmental impact compared to conventional plastic. The crockery is designed to degrade under specific conditions after use.
Solution Approach 2:
The patent changes the material parameters of the crockery by using oxo-degradable plastic instead of conventional plastic, and by controlling the degradation conditions (presence of oxygen, moisture, temperature) to achieve controlled decomposition after use, transforming the waste problem into a controlled environmental process.
2Object-generated harmful factors
If oxo-degradable plastic is used for disposable crockery, then environmental degradation is improved, but the plastic breaks down into microplastic under recycling conditions causing health stress
Solution Approach 1:
The patent converts the potential harm of plastic persistence into a benefit by designing oxo-degradable plastic that actively degrades after use. The degradation process, which would normally be considered harmful if uncontrolled, is transformed into a beneficial environmental disposal mechanism that reduces plastic waste accumulation.
Solution Approach 2:
The patent creates a controlled environment for degradation by requiring specific conditions (presence of oxygen, moisture, temperature range) that must be present for the oxo-degradation to occur properly, preventing uncontrolled breakdown into microplastics while ensuring complete degradation under appropriate conditions.
3Object-generated harmful factors
If reusable crockery is used instead of disposable, then environmental sustainability is improved, but hygiene regulations and contamination risks increase
Solution Approach 1:
The patent employs disposable crockery that is used once and then discarded, eliminating the need for repeated washing and sanitization processes. This approach maintains hygiene by ensuring each customer receives fresh, uncontaminated crockery while reducing environmental impact compared to reusable alternatives.
Solution Approach 2:
The patent implements a system where crockery is discarded after single use and then recovered through controlled degradation processes. The oxo-degradable plastic breaks down into harmless substances under specific environmental conditions, recovering the material in an environmentally friendly manner rather than persisting as waste.
4Object-generated harmful factors
If disposable crockery is eliminated to reduce plastic waste, then environmental impact is improved, but additional staff and operational complexity are required for cleaning and sanitization
Solution Approach 1:
The patent implements a self-service system where customers receive disposable crockery that is already prepared and ready for use. The crockery serves itself by being discarded after use, eliminating the need for staff to collect, transport, and clean reusable items. The system automatically reduces plastic waste through the use of oxo-degradable materials that break down environmentally.
Solution Approach 2:
The patent applies preliminary action by pre-preparing disposable crockery that is ready for immediate use. The crockery is manufactured and packaged in advance with the necessary degradation capabilities, so no additional processing or cleaning actions are required during or after the service process.
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
This solution reduces plastic waste, conserves resources, and maintains hygiene standards by ensuring all reusable containers are cleaned within the system, reducing the risk of contamination and environmental impact while allowing for seamless customer-specific orders without additional staff or operational disruptions.
