Loop-Sealed Driving Device Cover With Adhesive Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face issues with proper fitting and sealing, where even if components are not fitted correctly, the sealing may not be adequate, leading to potential leaks or failures.
Innovation Solution
A driving device with a loop-shaped recess and protrusion design, where an adhesive sealing compound is used to continuously adhere the recess and protrusion in a loop shape, ensuring proper alignment and sealing through positioning parts that guide the cover into place, using a silicone-based adhesive to fill gaps and prevent foreign matter entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover seal is used to seal the connector, then sealing performance is improved, but the complexity of assembly increases because the seal and cover must be assembled separately
Solution Approach 1:
The patent combines the cover seal and the cover into a single integrated component. The seal is formed as an integral part of the cover structure, eliminating the need for separate assembly steps. This merging approach maintains the sealing function while simplifying the assembly process by reducing the number of parts and assembly operations required.
2Reliability
If adhesive sealing compound is applied to adhere the cover, then sealing and adhesion are improved, but the precision of adhesive application increases to prevent gaps
Solution Approach 1:
The patent introduces a positioning part as an intermediary element between the cover and the driving unit. This positioning part provides precise alignment and spacing, ensuring that the adhesive sealing compound is applied at the correct location with consistent gap control. The positioning part acts as a mediator that eliminates the need for high-precision manual adhesive application, as it mechanically ensures proper positioning before adhesive bonding.
3Manufacturing precision
If positioning parts are added to guide the cover, then alignment precision is improved, but the device complexity increases
Solution Approach 1:
The positioning part is designed to perform multiple functions simultaneously: it guides the cover during assembly, maintains precise positioning, and works in conjunction with the adhesive sealing compound to ensure proper bonding. By integrating these functions into a single component rather than adding separate elements, the design achieves high alignment precision without proportionally increasing overall device complexity.
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 ensures that components are securely adhered and sealed, preventing leaks and maintaining the seal even under external forces or temperature changes, particularly beneficial for applications like electric power steering systems in vehicles.
Implementation Method 1
an adhesive sealing compound adhering the adhered recess and the adhered protrusion to each other continually in a loop shape
Implementation Method 2
adhesive sealing compound...fill gaps and prevent foreign matter entry

AI summary
A driving unit has an adhered recess that is in a loop shape. A cover has an adhered protrusion that is in a loop shape and is opposed to the adhered recess. An adhesive sealing compound adheres the adhered recess and the adhered protrusion to each other continually in a loop shape. A positioning part is configured to position the adhered protrusion relative to the adhered recess.
