Hybrid Soap Dispenser Actuation for Battery-Independent Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensers often rely solely on electric motors or manual operation, leading to issues such as battery dependence, maintenance challenges, and potential vandalism, resulting in inconsistent soap availability and user frustration.
Innovation Solution
A hybrid dispenser apparatus that combines an electric motor and a manually operable member to operate the dispensing valve structure, ensuring continuous soap access through alternative operation modes and incorporating features like lock-outs, counters, and indicators for efficient maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the dispenser relies solely on electric motor operation, then automation and convenience are improved, but battery dependence and maintenance challenges increase
Solution Approach 1:
The dispenser dynamically switches between electric motor operation and manual operation modes. The system is designed to be adaptable, allowing users to choose manual operation when battery power is unavailable or problematic, thus resolving the contradiction between automation and reliability.
Solution Approach 2:
The system changes its operational parameter from fully automatic to hybrid automatic-manual based on battery status. When batteries are depleted or malfunctioning, the system transitions to manual cranking mode, maintaining functionality while adapting to changing conditions.
2Ease of operation
If the dispenser relies solely on electric motor operation, then convenience is improved, but vulnerability to vandalism and power failure increases
Solution Approach 1:
The dispenser provides dynamic operational flexibility, allowing users to switch between electric and manual modes based on external conditions such as vandalism attempts or power failures. This adaptability ensures continuous operation regardless of external threats.
Solution Approach 2:
The system prepares for potential failures by incorporating a manual backup mechanism. Before complete system failure occurs, users can transition to manual operation, ensuring continuous availability of hand sanitizer even during vandalism or power failures.
3Reliability
If the dispenser uses hybrid operation modes, then reliability and soap availability are improved, but device complexity increases
Solution Approach 1:
The manual cranking mechanism serves multiple functions: it can operate independently when electric power fails, assist in priming the pump, and provide a backup during battery depletion. This multi-functionality justifies the added complexity by significantly improving reliability.
Solution Approach 2:
The patent merges electric motor operation and manual cranking mechanisms into a single integrated system. Both mechanisms work together through a common valve actuation system, reducing overall complexity compared to having completely separate systems while maintaining improved reliability.
4Reliability
If the dispenser incorporates manual operation capability, then resistance to vandalism and power failure is improved, but ease of operation decreases
Solution Approach 1:
The system dynamically adapts its operational mode based on conditions. During normal operation, the electric motor provides ease of use. When problems arise, the system transitions to manual mode, maintaining operation continuity while accepting increased effort as a temporary trade-off.

AI summary
A hybrid dispenser incorporating structural elements providing the ability to alternatively dispense soap or other liquid from a container either by an electric motor or manually including a pivoted actuator member having cam surfaces spaced from one another on opposite sides of the pivot location, a rotatable member rotated by the motor engaging one of the cam surfaces, and a manually operable member engaging the other cam surface.
