Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of disposable plastic canisters for soaps, shampoos, and other substances contributes significantly to landfill waste due to their slow decomposition and inability to be crushed, leading to space inefficiencies and environmental concerns.
Innovation Solution
A refillable dispenser housing with a pressure plate and push bar system that compresses a solution cartridge to dispense a measured amount of solution, allowing for incremental use and reducing waste by using replaceable cartridges made from biodegradable or flexible materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If disposable plastic canisters are used for solution dispensing, then convenience and low cost are achieved, but waste accumulation and landfill space consumption increase significantly
Solution Approach 1:
The system is divided into a reusable dispenser housing and replaceable solution cartridges. The housing contains the dispensing mechanism and can be refilled multiple times, while only the solution cartridges are discarded. This segmentation allows the expensive, complex dispensing mechanism to be reused while only the consumable solution is replaced, dramatically reducing waste compared to disposing of entire canisters.
Solution Approach 2:
The invention enables recovery and reuse of the dispenser housing, pump mechanism, and control electronics. Only the solution cartridges are discarded after use. The system is designed so that the housing can be easily refilled with new cartridges, recovering the value of the dispensing mechanism and eliminating the need to discard the entire assembly.
2Ease of manufacture
If disposable plastic canisters are used, then initial cost is reduced, but long-term environmental impact and landfill space increase due to inability to crush or decompose
Solution Approach 1:
The invention changes the material parameters of the solution cartridge from rigid, non-decomposable plastic to flexible, biodegradable materials. This parameter change allows the cartridges to be compressed to minimal volume after use and enables biological decomposition, fundamentally altering the environmental persistence from centuries to months or years.
Solution Approach 2:
The solution cartridge is constructed from composite materials including flexible outer layers and biodegradable components. This composite structure provides the necessary containment and flexibility while enabling decomposition, combining the benefits of durability during use with environmental friendliness after disposal.
3Device complexity
If disposable canisters are used, then simplicity of design is maintained, but space efficiency is reduced due to interior volume that cannot be crushed
Solution Approach 1:
The solution cartridge employs flexible shells and thin film materials instead of rigid plastic containers. This flexibility allows the cartridge to be compressed to a fraction of its original volume after the solution is dispensed, dramatically reducing landfill space occupation while maintaining structural integrity during the dispensing process.
Solution Approach 2:
The system transitions from static, rigid containers to dynamic, flexible cartridges that change volume during use. The flexible cartridge expands to contain the full solution volume when new, then contracts and compresses to minimal volume as solution is dispensed and after use, optimizing space utilization throughout the product lifecycle.
4Loss of substance
If a refillable pressure system is implemented, then waste is reduced through reuse, but device complexity increases with pressure plate, push bars, and control mechanisms
Solution Approach 1:
The system incorporates automatic solution dispensing through the pressure plate and pump mechanism that operates with minimal user intervention. The pressure system automatically pressurizes the cartridge and dispenses solution through the applicator head, eliminating the need for manual pumping or complex user操作, thereby justifying the increased mechanism complexity through automation and ease of use.
Solution Approach 2:
The pressure system and dispenser housing are designed as universal components that can accommodate multiple types of solution cartridges. The same basic mechanism handles different solution viscosities, volumes, and cartridge formats, maximizing the reuse value of the complex components and reducing overall waste through long-term versatility.

AI summary
A refillable solution dispenser including a dispenser housing having a base with a plurality of sidewalls defining an interior volume of the housing. A lid defining the top of the housing located on the top of the sidewalls is movably secured to allow access to the interior of the housing. An actuator mechanism is disposed through a top of the housing. At least one dispensing device is moveably connected within the housing. The dispensing device includes a pressure system connected to the actuator mechanism. The pressure system will move a pressure apparatus located within the housing forcing a solution from a solution reservoir through a dispensing passageway and out of the nozzle.
