Sleeve Centering Mechanism for Buttons Against Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Buttons attached to devices in various sectors, such as white goods and automotive, tend to lean downwards due to gravity, affecting the quality perception and appearance by not remaining centered in their sleeves.
Innovation Solution
A sleeve design featuring a body with a protrusion, thread, nut, holders, openings for LEDs, tabs, and holes, which allows the button and switch to be centered by fixing the body in place and using holders to maintain the button's position, while also enabling LED lighting and easy part removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If buttons are placed in sleeves using conventional methods, then the buttons can be installed on devices, but the buttons lean downwards and do not remain centered due to gravity
Solution Approach 1:
The patent employs a spring mechanism that exerts an upward elastic force to counterbalance the downward gravitational force on the button. The spring is pre-compressed and pushes the button upward against the retaining wall, creating a counterweight effect that prevents the button from leaning downward and ensures it remains centered in the sleeve.
Solution Approach 2:
The spring is pre-compressed during assembly to store elastic potential energy before the button is fully installed. This preliminary action ensures that the spring is already exerting the necessary upward force to counteract gravity as soon as the button is in place, preventing the button from leaning downward without requiring additional adjustment mechanisms.
2Ease of manufacture
If the sleeve structure is simplified, then manufacturing becomes easier, but the ability to keep the button centered is compromised
Solution Approach 1:
The sleeve is divided into distinct functional segments: the button-receiving chamber with retaining walls for centering, the spring housing for positioning the elastic element, and the LED opening area. This segmentation allows each portion to be optimized for its specific function while maintaining overall manufacturing simplicity through modular design and standard forming techniques.
Solution Approach 2:
The spring acts as an intermediary element between the sleeve structure and the button. Rather than requiring complex mechanical centering mechanisms in the sleeve itself, the spring mediates the centering function by exerting elastic force on the button, allowing the sleeve to remain structurally simple while achieving precise button positioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively keeps the button and switch centered within the sleeve, enhancing the aesthetic appeal and functionality by preventing downward leaning, thus improving the overall device appearance and usability.
Implementation Method 1
at least one spring which is placed in the body and which has an elastic force in a direction opposite to the direction of gravity
