Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sealing of electrical modules in electronic devices is often poor, allowing external fluids to enter and cause shorting or damage to internal components.
Innovation Solution
The electrical module design includes a base, a composite component with a conductive sheet embedded in a pad, and a pressing sheet that enhances sealing by using a locking mechanism to apply pressure, preventing fluid ingress through the connections between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrical module assembly is used, then device complexity is reduced, but sealing performance deteriorates allowing fluid ingress
Solution Approach 1:
The patent merges the sealing function and electrical connection function into a single integrated module. The base structure combines the sealing surface and electrical contact points, while the composite component integrates the conductive sheet with the pressing mechanism. This merging eliminates the need for separate sealing components and simplifies the overall assembly process while maintaining effective sealing performance.
Solution Approach 2:
The patent employs a nested structure where the conductive sheet is embedded within the base, and the composite component is positioned within the module cavity. The pressing sheet is then placed over the composite component, creating a layered nested arrangement. This nesting approach maximizes space utilization and ensures that each component is securely positioned while maintaining the sealing integrity of the overall structure.
2Reliability
If sealing components are added to prevent fluid ingress, then reliability improves, but ease of manufacture deteriorates
Solution Approach 1:
The sealing function is merged with the base structure and composite component design. The base includes integrated sealing surfaces, and the composite component incorporates both electrical conductivity and sealing capabilities. This merging eliminates the need for additional separate sealing components, thereby improving reliability against fluid ingress while maintaining ease of manufacture through reduced part count and simplified assembly steps.
3Reliability
If a pressing mechanism is used to enhance sealing, then sealing performance improves, but device complexity increases
Solution Approach 1:
The pressing sheet is designed to automatically apply pressure to the composite component when installed, utilizing the natural compression properties of the materials. The elastic or resilient nature of the pressing sheet allows it to self-adjust and maintain optimal sealing pressure without requiring external actuation mechanisms or complex control systems. This self-service approach enhances sealing effectiveness while minimizing the addition of complex mechanical components.
