Motor Housing Interference Fit Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor housings for vehicles require additional tools or locking components to ensure air-tightness, increasing production costs and time, and affecting the lifespan of products.
Innovation Solution
A motor housing design featuring a seat and cover with corresponding connecting portions that are connected through relative movement, eliminating the need for additional tools and locking components, ensuring air-tightness through tight fitting or wedging, and optionally using adhesives for enhanced strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rivets are used to combine the seat and cover, then air-tightness is ensured, but production cost increases due to machine requirements
Solution Approach 1:
The patent removes the rivets and machines from the assembly system, extracting the harmful elements that increase cost and complexity while maintaining the air-tight sealing function through an alternative interference fit design
Solution Approach 2:
The connecting portions are designed to self-assemble through interference fit without requiring external machines or tools. The seat and cover automatically secure themselves through the geometric design of the connecting portions, eliminating the need for riveting machines
2Reliability
If screws are used to combine the seat and cover, then air-tightness is ensured, but production time increases
Solution Approach 1:
The connecting portions are designed to self-assemble through interference fit without requiring external machines or tools. The seat and cover automatically secure themselves through the geometric design of the connecting portions, eliminating the need for riveting machines
3Reliability
If additional locking components are used to ensure air-tightness, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The patent removes the rivets and machines from the assembly system, extracting the harmful elements that increase cost and complexity while maintaining the air-tight sealing function through an alternative interference fit design
Solution Approach 2:
The patent merges the sealing function and the connection function into a single integrated structure. The connecting portions themselves provide both the mechanical connection and the air-tight seal, eliminating the need for separate gaskets or sealing components
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
This design reduces production costs and time while extending the lifespan of motor products by ensuring air-tightness without additional tools or locking components, facilitating efficient assembly and enhanced connection strength.
Implementation Method 1
The first and second connecting portions are connected by the relative movement of the seat and the cover so that the seat and the cover are combined tightly
Implementation Method 2
the seat and the cover are combined tightly through a plurality of rivets

AI summary
A motor includes a motor body and a housing for covering and accommodating the motor body. The housing includes a seat and a cover. The seat has at least one first connecting portion disposed at the circumference of the seat, and the cover has at least one second connecting portion disposed at the circumference of the cover and corresponding to the first connecting portion. The first and second connecting portions are connected by the relative movement of the seat and the cover, so that the seat and the cover can be combined tightly.
