Insert-Molded Ventilated Housing for Waterproof Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable devices face increased manufacturing costs and reduced space for additional components due to the use of waterproof and ventilated films combined with auxiliary structures like screw holes, fixing frames, and foam components, which also compromise the waterproof effect.
Innovation Solution
A wearable device design incorporating a plastic housing combined with a ventilated metal member through insert molding, forming a closed space with an electronic module, eliminating the need for additional components like waterproof and ventilated films and auxiliary structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof and ventilated film is used with auxiliary structures (screw holes, fixing frame, foam component), then waterproofing and ventilation are achieved, but manufacturing cost increases and device space decreases
Solution Approach 1:
The patent merges the waterproof and ventilated film with the housing structure itself. The housing is designed with a through-hole that directly provides ventilation while maintaining waterproofing, eliminating the need for separate waterproof and ventilated films and their auxiliary fixing structures. This integration reduces the number of components while achieving the same waterproofing function.
2Reliability
If a waterproof and ventilated film with auxiliary structures is used, then waterproofing is maintained, but manufacturing cost increases
Solution Approach 1:
The patent combines the waterproofing function directly into the housing structure through the through-hole design. This eliminates the need for separate waterproof films, fixing frames, screws, and foam components, thereby reducing the number of parts to be manufactured, stored, and assembled, which directly lowers manufacturing costs.
Solution Approach 2:
The patent extracts and removes the unnecessary auxiliary structures (fixing frame, screws, foam components) from the conventional design. By taking out these redundant elements and retaining only the essential through-hole structure in the housing, the design simplifies the manufacturing process and reduces costs while maintaining waterproofing effectiveness.
3Strength
If screw holes, fixing frame, screw, and foam component are used to secure waterproof film, then bonding strength is improved, but usable space in device decreases
Solution Approach 1:
The patent merges the functions of multiple components (waterproof film, fixing frame, screws, foam component) into a single integrated housing structure with a through-hole. This eliminates the need for separate bonding mechanisms and auxiliary components, thereby maximizing the usable internal space of the device while maintaining structural integrity and waterproofing.
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
Reduces manufacturing costs and increases usable space within the device by integrating a ventilated metal member with the plastic housing, allowing for larger components and improved waterproofing without additional parts.
Implementation Method 1
The plastic housing is combined with a periphery of the ventilated metal member through insert molding
Implementation Method 2
The ventilated metal member seals the through hole and is waterproof and ventilated
