Liquid Dispenser Nozzle Signalling Apertures for Caption Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispenser device heads have unclear symbols or captions on the nozzle, leading to usability issues and high production costs.
Innovation Solution
A dispenser device head with a nozzle featuring signalling apertures on the lateral wall that define clear captions or symbols, such as 'ON' and 'OFF', and a contrasting signalling element to enhance visibility, while allowing the nozzle to rotate for fluid control, and a cover with indicator apertures to highlight the selected configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If raised captions or symbols are made by overmoulding on the nozzle, then the markings are visible, but the production costs are high
Solution Approach 1:
The patent extracts the marking function from the nozzle itself by introducing separate signalling elements (apertures or recesses) that define the captions or symbols. These signalling elements are integrated into the nozzle structure but the actual visible markings are created by the interaction between light and these elements rather than by adding material through overmoulding, thereby reducing manufacturing complexity and cost while maintaining visibility.
Solution Approach 2:
The patent utilizes optical contrast principles where signalling elements (apertures or recesses) create visible distinctions through light interaction. The markings become visible through the contrast created by light passing through or reflecting off different surfaces, eliminating the need for colored overmoulding and reducing production costs while maintaining clear visibility of captions.
2Ease of manufacture
If conventional markings are used on the nozzle, then production is simpler, but the symbols or captions are not clear
Solution Approach 1:
The patent introduces signalling elements (apertures or recesses) as intermediaries between the nozzle structure and the user's perception. These elements act as mediators that enhance the visibility of captions by creating optical contrast through light interaction, without requiring complex manufacturing processes. The signalling elements translate simple structural features into clear visual information.
3Ease of operation
If the nozzle rotates for fluid control, then operation is flexible, but the visibility of captions in different positions is reduced
Solution Approach 1:
The patent makes the signalling elements universal by positioning them radially around the nozzle circumference rather than at a single fixed location. This allows the captions to remain visible regardless of the nozzle's rotational position, as at least one signalling element will always be oriented toward the user. This multi-position visibility maintains operational flexibility while solving the information loss problem.
