Hybrid Soap Dispenser Actuation for Power-Outage Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid dispensers rely exclusively on either manual or electric operation, leading to issues such as inability to function during power outages, increased maintenance, and potential vandalism due to reliability concerns.
Innovation Solution
A hybrid dispenser apparatus that combines manual and electric operation by using a cabinet with a movable cover and an actuator mechanism, incorporating both a manual pump and an electric motor to ensure continuous soap access, reducing reliance on batteries and maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the dispenser is dedicated to electrically operated system, then dispensing automation is improved, but reliability during power outage deteriorates
Solution Approach 1:
The dispenser is designed to perform multiple functions: it can operate automatically via electric motor when powered, and manually via cover movement when powerless. The actuator mechanism serves dual purposes - it can be driven by electric motor for automated dispensing or by manual cover movement for manual operation, making the system universal and adaptable to different operating conditions.
Solution Approach 2:
The system dynamically switches between electric motor-driven operation and manual operation based on power availability. The actuator mechanism is designed to accept input from either the electric motor or direct manual manipulation through the cover, allowing the dispenser to adapt its mode of operation to current conditions, thereby maintaining reliability during power outages.
2Extent of automation
If the dispenser relies on batteries, then automated operation is improved, but maintenance requirements increase
Solution Approach 1:
The manual operation capability allows users to service the dispenser themselves by simply moving the cover to actuate the pump, eliminating the need for complex battery replacements or electrical repairs. The system can continue to function in manual mode even when electrical components require maintenance, reducing overall maintenance burden.
Solution Approach 2:
The dual operation system provides redundancy - if electrical components need maintenance, the dispenser can continue operating manually. This reduces the impact of maintenance requirements on overall system availability and reduces the frequency of service interruptions.
3Device complexity
If the dispenser is manually operated, then simplicity is improved, but productivity decreases
Solution Approach 1:
The invention merges manual and electric operation systems into a single unified dispenser. The manual cover movement and electric motor both drive the same actuator mechanism and pump, combining the simplicity of manual operation with the automated efficiency of electric operation in one integrated system.
Solution Approach 2:
The system dynamically selects between manual and electric operation modes based on needs. When high productivity is required, the electric motor provides automated dispensing. When simplicity or power independence is needed, manual operation via cover movement is used. This dynamic flexibility allows the system to optimize for either simplicity or productivity as needed.
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
The hybrid dispenser ensures consistent soap availability, reducing complaints and vandalism by allowing operation through either manual or electric power, minimizing maintenance issues and ensuring soap access regardless of power availability.
Implementation Method 1
an electric motor (40) disposed in the housing; a pump connectable to the liquid material container to dispense liquid from the container; and an actuator mechanism (30) operatively associated with the pump to dispense liquid from the liquid material container in response to operation of the electric motor (40)
Implementation Method 2
various mechanisms for pumping or exerting pressure on the liquid to facilitate dispensing
