Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The preparation of mixtures of substances, such as media or buffers, in laboratory settings is time-consuming and inefficient due to manual handling and the high costs and waste associated with using pre-made liquid solutions, which often expire or require extensive storage and refrigeration.
Innovation Solution
A device comprising disposable containers and dosing systems for solid and fluid components, allowing for precise dosing and mixing without the need for expensive pumps, with a design that enables sterile preparation and filtration, reducing waste and storage needs by allowing for on-demand production of desired quantities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If pre-made liquid solutions are used, then immediate availability is improved, but storage costs and waste increase
Solution Approach 1:
The pre-made liquid solution is segmented into individual dosage units (sachets or vials), each containing a specific amount of substance. This allows users to take only the required portion without wasting the entire container's contents, directly addressing the waste problem while maintaining immediate availability of needed doses.
Solution Approach 2:
The substance is pre-packaged in sterile, ready-to-use dosage units before distribution. This preliminary preparation eliminates the need for on-site storage of large quantities and reduces waste by providing exactly the amount needed for each application, resolving the contradiction between availability and waste.
2Stability of the object's composition
If pre-made liquid solutions are stored in refrigerators, then stability is improved, but energy consumption and space requirements increase
Solution Approach 1:
The invention uses disposable, single-use packaging (sachets or vials) that contains the substance in a stable, pre-prepared form. Each unit is sealed to maintain stability without requiring refrigeration, and is discarded after single use. This eliminates the need for energy-consuming refrigeration infrastructure while maintaining composition stability throughout the product shelf life.
Solution Approach 2:
The substance formulation or packaging parameters are modified to enable ambient temperature storage. This could involve changing the chemical stability through formulation adjustments or using packaging materials that protect against degradation at room temperature, thereby eliminating refrigeration requirements while maintaining stability.
3Adaptability or versatility
If manual preparation methods are used, then flexibility in customization is improved, but labor time and complexity increase
Solution Approach 1:
The substance is pre-measured, pre-mixed, and pre-packaged in the correct concentrations and volumes during manufacturing. This preliminary preparation eliminates the time-consuming manual tasks of weighing, measuring, and mixing on-site, while the range of available pre-packaged options maintains customization flexibility for different applications.
Solution Approach 2:
The product is designed to be ready-to-use upon opening, requiring no additional preparation steps by the end user. The packaging itself provides the necessary dosing and mixing functions, allowing users to simply add the contents to their application without manual intervention, thus eliminating labor time while preserving adaptability through product selection.
