Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lavatory systems require multiple custom-designed components for varying heights, which complicates installation and accessibility, especially for users with disabilities, and often lack efficient hand washing and drying solutions that prevent water from dripping on the floor.
Innovation Solution
A modular lavatory system with integrated hand washing stations at different heights, featuring a control system that inhibits simultaneous activation of fixtures, and powered by a photovoltaic system for renewable energy, allowing hands-free operation and efficient water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple custom-designed lavatory systems are installed at various heights, then accessibility for different users is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent applies universality by designing a single modular lavatory system that can be installed at multiple heights to serve different user needs. The system includes adjustable mounting mechanisms and reconfigurable components that allow the same unit to accommodate wheelchair users, standing users, and children, eliminating the need for multiple custom-designed systems.
Solution Approach 2:
The lavatory system is divided into modular segments including separate basin modules, mounting brackets, and support structures. This segmentation allows the system to be configured at different heights and reconfigured as needed, providing accessibility versatility while maintaining a standardized design that reduces overall complexity.
2Area of stationary object
If hand dryers are positioned away from wash basins, then space utilization is improved, but ease of operation deteriorates as users must leave the washing station
Solution Approach 1:
The patent merges the hand dryer and wash basin into an integrated unit where the hand dryer is positioned directly adjacent to the basin. This combination allows users to complete the entire hand washing and drying process at one location without moving, significantly improving ease of operation while the vertical stacking maintains efficient space utilization.
3Productivity
If water flow is not controlled during hand drying, then productivity is improved, but loss of substance increases as water drips on the floor
Solution Approach 1:
The patent introduces a control system as an intermediary between the water supply and the hand drying process. Sensors detect when hands are present at the basin and automatically control water flow, shutting it off during the hand drying phase. This prevents water from dripping on the floor while maintaining efficient hand drying productivity.
Solution Approach 2:
The system uses feedback from sensors that detect hand presence and position to dynamically control water flow. When the sensor detects that hands are positioned for drying rather than washing, the control system automatically reduces or stops water flow, preventing waste while ensuring the hand drying process remains efficient and productive.

AI summary
A lavatory system is disclosed including one or more integrated hand washing stations. Each hand washing station includes a basin, a faucet, a solenoid valve configured to control water flow to the faucet, and an electric hand dryer located adjacent the basin and the faucet so that the user of the washing station may use the faucet and the electric hand dryer without leaving the washing station. The electric hand dryer preferably includes an outlet to direct air across the associated basin so that any water that drips from the user's hands fall within the basin. A control system may be provided to control activation of the fixtures such as the solenoid valve, the electric hand dryer, and/or soap dispenser. The control system may be configured to inhibit simultaneous activation of the solenoid valve and the hand dryer. A photovoltaic system may be provided to provide power.
