Engine Generator Single Cover Filter Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine generators require two covers for maintenance, making it time-consuming to replace the air cleaner filter and hindering weight reduction.
Innovation Solution
An engine generator design with a single air cleaner cover that allows for easy access to the filter accommodation section, reducing the number of components and weight by integrating the filter accommodation section into the case wall and using a single cover for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two covers (maintenance cover and air-cleaner cover) are used to access the filter, then the filter can be protected and maintained, but the number of components increases and maintenance time is extended
Solution Approach 1:
The patent combines the maintenance cover and air-cleaner cover into a single integrated cover structure. This single cover provides both maintenance access and air cleaner protection functions, eliminating the need for separate covers while maintaining protective capabilities.
Solution Approach 2:
The single cover serves multiple functions: it acts as both the maintenance cover for accessing internal components and the air-cleaner cover for protecting the air filter. This multi-functional design reduces component count while maintaining all necessary protective and access functions.
2Reliability
If two covers are used for maintenance access, then component protection is ensured, but maintenance time increases
Solution Approach 1:
By merging the maintenance cover and air-cleaner cover into one unified component, the patent enables simultaneous access to both the maintenance area and air cleaner through a single cover removal action, thereby reducing maintenance time while maintaining protection.
Solution Approach 2:
The single cover is designed to provide preliminary access to both the maintenance compartment and air cleaner together, allowing maintenance personnel to service both areas in one operation rather than sequentially removing separate covers.
3Adaptability or versatility
If two covers are used in the engine generator, then functional requirements are met, but the overall weight increases
Solution Approach 1:
The patent merges two separate cover components into a single integrated cover, directly reducing the total number of parts and associated weight while maintaining all necessary functional capabilities for protection and access.
Solution Approach 2:
The single multi-functional cover replaces two separate covers, reducing the total material required and thus the weight, while still providing all necessary protective and access functions that the two original covers provided.

AI summary
An engine generator including an engine, a generator and an air cleaner inside a case is disclosed. A wall section of the case is dented in the internal direction of the case to provide a filter accommodation section with a space for accommodating a filter. The space has an opening that opens toward the exterior of the case. The filter accommodation section has an outside-air intake port. The opening is blocked by an air cleaner cover.
