Pushbutton Assembly Using Positioning Cavities and Conveying Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for assembling pushbuttons for liquid dispensing systems are limited by requiring individual positioning of components, which restricts assembly rates to approximately two per second due to the need for manual alignment and stopping of the conveying process.
Innovation Solution
A method and installation that utilize actuation bodies with positioning cavities and a conveying path with complementary profiles to facilitate continuous assembly of pushbuttons, allowing for the alignment and assembly of components during conveyance, thereby increasing assembly rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual positioning of bodies is carried out by inserting a counter-form, then positioning precision is improved, but productivity deteriorates due to conveying stoppage
Solution Approach 1:
The positioning cavity is pre-formed in the body during molding, and the conveying path is designed with complementary profiling that automatically positions the body as it moves through the conveyor. This preliminary preparation eliminates the need for stoppage-based positioning operations.
Solution Approach 2:
The conveying path maintains continuous motion while simultaneously performing the positioning function through its complementary profile. The body is positioned automatically during conveyance without interrupting the production flow, achieving both precision and high productivity.
2Manufacturing precision
If conveying is stopped to position the body, then positioning accuracy is improved, but productivity deteriorates
Solution Approach 1:
The conveying path's complementary profile automatically positions the body through its own geometry without requiring external positioning operations or stoppage. The system serves itself by incorporating the positioning function into the continuous conveyance mechanism.
3Productivity
If assembly rate is increased to five pushbuttons per second, then productivity is improved, but positioning complexity increases
Solution Approach 1:
The positioning function is merged with the conveying function by integrating the complementary profile directly into the conveying path. This combination eliminates the need for separate positioning mechanisms, reducing overall system complexity while enabling high-speed assembly.

AI summary
A method of assembling pushbuttons for a liquid dispensing system, in which each pushbutton comprises an actuation body and at least one other component assembled with said body in a given position, said method making provision for using bodies on which a positioning cavity is formed, and continuously supplying a station for assembling the bodies and the other components by means of a path for conveying said bodies, said path having a complementary profile intended to cooperate with the cavities in order to carry out the positioning of said bodies in said conveying path, so as to carry out the assembly of the other components on the bodies thus positioned during their conveying to the assembly station. The invention also concerns an installation for implementing this method, and a pushbutton assembled by implementing said method.
