Adjustable Waterproof Test Fixture for Diverse Smartphone Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproofing test apparatuses are limited to specific types of semi-finished products, leading to resource waste when new smartphone models are released, as they cannot adjust to varying product shapes and configurations.
Innovation Solution
A waterproofing test apparatus with adjustable positioning of a movable block and sealing block, allowing it to accommodate various types of semi-finished products by replacing inner and outer pads, and adjusting the position of these blocks within the body and cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproofing test apparatus is designed for a specific type of semi-finished product, then the testing precision and reliability are improved, but the adaptability to various product types deteriorates
Solution Approach 1:
The sealing block is designed to be movable along the inner surface of the cover, allowing its position to be dynamically adjusted according to different semi-finished product configurations. This dynamic positioning capability enables the same apparatus to adapt to various product types while maintaining reliable sealing and testing performance
Solution Approach 2:
The apparatus incorporates a universally adaptable sealing mechanism where the movable sealing block can be positioned at different locations to seal various hole patterns. This universal design allows a single apparatus to perform waterproofing tests on multiple types of semi-finished products without requiring dedicated equipment for each product type
2Measurement precision
If a dedicated waterproofing test apparatus is manufactured for each smartphone model, then the measurement precision for that specific model is improved, but resource waste increases
Solution Approach 1:
The waterproofing test apparatus is designed as a universal platform that can test multiple smartphone models through adjustable sealing blocks and replaceable pads. This eliminates the need to manufacture dedicated apparatus for each model, reducing resource waste while maintaining precise measurement capability across different product types
Solution Approach 2:
The sealing system is segmented into replaceable components including different types of pads and a movable sealing block that can be independently adjusted. This segmentation allows the apparatus to be reconfigured for different smartphone models without replacing the entire device, reducing resource consumption while maintaining measurement precision
3Device complexity
If the movable block position is fixed in the cover, then the device complexity is reduced, but the adaptability to various semi-finished products deteriorates
Solution Approach 1:
The sealing block is designed to be movable along the inner surface of the cover, allowing its position to be dynamically adjusted according to different semi-finished product configurations. This dynamic positioning capability enables the same apparatus to adapt to various product types while maintaining reliable sealing and testing performance
Solution Approach 2:
Instead of making the entire cover adjustable, only the sealing block is made movable while the cover structure remains fixed. This partial action approach provides the necessary adaptability for different products without significantly increasing overall device complexity
