Waterproof Projector Push Button Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof and autonomous lighting devices face challenges in ensuring a simple and easy-to-install sealing mechanism for the push button, which is complex to produce and install due to the need for multiple parts.
Innovation Solution
A push button design with a flexible collar and a longitudinal rod that acts as an actuator, mounted in a guide within the sealed chamber, allowing for easy manipulation and magnetic attachment for secure positioning, simplifying the sealing process and reducing the number of required parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional push button sealing mechanism is used, then watertightness is achieved, but the design becomes complex and requires many parts
Solution Approach 1:
The patent combines multiple sealing functions into a single integrated push button assembly. The push button incorporates a sealing ring directly integrated into its structure, eliminating the need for separate sealing components. This merging of the button and sealing elements into one unit achieves watertightness while reducing part count and simplifying the overall design.
2Reliability
If a traditional push button sealing mechanism is used, then watertightness is achieved, but installation becomes difficult
Solution Approach 1:
By integrating the sealing ring directly into the push button structure, the patent creates a single-component assembly that is both watertight and easy to install. The merged design eliminates complex assembly steps required for traditional multi-part sealing mechanisms, allowing installation by simply positioning the integrated button into the designated opening.
3Reliability
If the push button is positioned on the casing, then sealing is achieved, but user accessibility is reduced
Solution Approach 1:
The patent repositions the push button from the side casing to the front lens surface, utilizing a different spatial dimension for control access. This dimensional relocation maintains sealing integrity through the integrated sealing ring while dramatically improving user accessibility, as the button on the front surface is easily reachable and operable without requiring access to side or rear compartments.
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 provides a watertight and easily accessible push button mechanism that is simple to install, ensuring effective sealing with minimal components and allowing for easy user operation, while maintaining the device's autonomy and waterproof integrity.
Implementation Method 1
The collar is preferably flexible with elastic properties, such that it is in an undeformed position when no actuation pressure is applied to the push button, the active portion of the rod being distant from the control element when the collar is in this undeformed position
Implementation Method 2
The housing is advantageously provided with a magnetic fixing
