Solution Overview
Problem
Conventional hand-washing systems with fluid-dispensing brushes often waste cleaning product due to inefficient dispensing mechanisms, leading to excess product dripping from the brush heads and requiring frequent replenishment.
Innovation Solution
A hand-washing system comprising a handheld implement with a handle and head, a base with a basin and pump, and a product container, where the pump conveys product from the container to the basin through a through-hole, allowing users to actuate the pump by plunging the implement, ensuring efficient product distribution and minimizing waste by pooling excess product for reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fluid-dispensing brush with valve mechanism is used, then cleaning product can be dispensed directly onto brush bristles, but excess product drips from the brush head causing waste and requiring frequent replenishment
Solution Approach 1:
The system divides the product dispensing function into two separate components: a base unit that holds the product reservoir and pump mechanism, and a handheld implement that receives product in a basin. This segmentation allows the product to be dispensed controllably into a containment area rather than directly onto the brush, preventing drips and waste.
Solution Approach 2:
A basin is introduced as an intermediary component between the pump and the brush head. The basin receives the dispensed product and allows it to pool before being applied to the brush, serving as a buffer that prevents direct dripping and enables controlled application.
2Productivity
If a pump mechanism is added to convey product from reservoir to basin, then efficient product distribution is achieved, but device complexity increases
Solution Approach 1:
The pump mechanism is designed to be manually actuated by the user through simple plunging or pressing motions. The system serves itself by using the user's own action to drive the pump, eliminating the need for external power sources, motors, or complex control systems while maintaining efficient product distribution.
Solution Approach 2:
The pump utilizes basic pneumatic or hydraulic principles where manual pressure applied to a plunger or piston displaces product from the reservoir through a valve system into the basin. This simple mechanical fluid displacement achieves efficient product conveyance without requiring complex mechanical or electronic systems.
3Loss of substance
If excess product is pooled in the basin for reuse, then product consumption is reduced, but the basin requires frequent cleaning and maintenance
Solution Approach 1:
The system recovers excess product by pooling it in the basin after dispensing, allowing it to be reused in subsequent dispensing cycles. This recovery mechanism reduces overall product consumption while the basin's design facilitates easy emptying and cleaning to maintain hygiene.

Function Achieved in This Case
The system neatly and efficiently dispenses liquid products onto handheld implement heads, reducing waste and allowing for easy replenishment of the product pool, thereby enhancing cleaning efficiency and reducing product consumption.
Implementation Method 1
The pump conveys the product from the reservoir to the inner cavity via at least one through-hole in the basin
