Electric Compressor Nameplate Mounting via Housing Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric compressors with soundproof covers face challenges in securely attaching nameplates due to material differences between the casing and soundproof cover, leading to instability and reliability issues.
Innovation Solution
The electric compressor design includes a housing with protrusions that extend beyond the soundproof cover, allowing the nameplate to be securely attached to these protrusions, thereby ensuring stability and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nameplate is attached to the outer surface of the soundproof cover, then the nameplate is visible from outside the compressor, but the nameplate does not adequately adhere to the soundproof cover due to material differences
Solution Approach 1:
The patent introduces a mounting leg as an intermediary component between the housing and the soundproof cover. The mounting leg protrudes through the soundproof cover, allowing the nameplate to be attached to the housing structure rather than directly to the soundproof cover. This intermediary structure resolves the material incompatibility issue while maintaining visibility.
2Object-affected harmful factors
If the soundproof cover covers the outer peripheral surface of the casing, then noise suppression is achieved, but the nameplate cannot be checked from outside the compressor
Solution Approach 1:
The patent segments the housing structure by adding a mounting leg that protrudes through the soundproof cover. This creates a distinct attachment region that extends beyond the soundproof cover, allowing the nameplate to be positioned in a zone that is both structurally supported and visually accessible.
3Ease of manufacture
If adhesive for the casing is used to attach the nameplate to the soundproof cover, then attachment is simplified, but the nameplate does not stably attach due to material differences
Solution Approach 1:
The mounting leg serves as a mediator that eliminates the need for adhesive between the nameplate and soundproof cover. The nameplate is attached to the mounting leg (which is part of the housing structure), bypassing the material incompatibility between the casing adhesive and soundproof cover material.

AI summary
An electric compressor includes a compression part configured to compress fluid, an electric motor configured to drive the compression part, a housing accommodating the compression part and the electric motor, a soundproof cover covering the housing, and a nameplate attached to the housing and including a predetermined information. The housing includes a protrusion that is a part of the housing and protrudes out of the soundproof cover through a hole formed in the soundproof cover. The nameplate is provided on the protrusion.
