Solution Overview
Problem
Existing compressor designs face challenges in achieving weight reduction while maintaining stiffness, leading to increased mold complexity and costs, which can deteriorate productivity.
Innovation Solution
A compressor design featuring a reinforcement part with a hollow structure integrally formed with the attachment and housing, extending from the side surface of the attachment part to the outer peripheral surface, providing enhanced stiffness and weight reduction through a simple structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a large number of reinforcement parts are formed at the attachment part to provide stiffness of the housing, then the stiffness of the housing is enhanced, but the mold structure becomes complicated and mold cost increases
Solution Approach 1:
The reinforcement part is integrally formed with the attachment part and housing as a single molded component, merging multiple structural elements into one unified part. This eliminates the need for separate reinforcement components and simplifies the mold structure while maintaining the stiffness-enhancing function.
Solution Approach 2:
The reinforcement part is strategically positioned extending from the side surface of the attachment part along the bolt hole to the outer peripheral surface of the housing. This localized reinforcement provides stiffness where needed without requiring comprehensive reinforcement throughout the entire housing structure.
2Strength
If a large number of reinforcement parts are formed at the attachment part to provide stiffness of the housing, then the stiffness of the housing is enhanced, but productivity of the housing and compressor deteriorates
Solution Approach 1:
By integrating the reinforcement part with the attachment part and housing into a single molded component, the number of manufacturing steps is reduced. The housing can be produced in one molding operation rather than requiring multiple steps for assembling separate reinforcement parts, thereby improving productivity.
3Weight of moving object
If lightweight material is used for housing to reduce weight, then weight reduction is achieved, but stiffness of the housing may be insufficient
Solution Approach 1:
The reinforcement part is strategically positioned extending from the side surface of the attachment part along the bolt hole to the outer peripheral surface of the housing. This localized reinforcement provides stiffness where needed without requiring comprehensive reinforcement throughout the entire housing structure.
Solution Approach 2:
The reinforcement part is integrally formed with the attachment part and housing as a single molded component, merging multiple structural elements into one unified part. This eliminates the need for separate reinforcement components and simplifies the mold structure while maintaining the stiffness-enhancing function.

AI summary
The object of the present invention is to enhance the stiffness of the attachment part and the entire housing of the compressor with a simple configuration. A compressor (100), includes: an attachment part (211) protruded from an outer peripheral surface (210) of a housing (102) and including a first end surface (215) abutting on an attached member, a second surface (216) opposed to the first end surface, and a bolt hole (211a) opened to both the first end surface and the second end surface; and a reinforcement part (220) integrally formed with the attachment part and the housing and extending from a side surface (211b) of the attachment part formed along the bolt hole to the outer peripheral surface of the housing. The reinforcement part includes a hollow portion (218) that is formed by closing the first end surface side and opening the second end surface side.
