Compressor Foot Structure for Easy Gasket Fitting and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compressor designs face difficulties in gasket fitting and rotational stability during startup and shutdown, requiring the use of multiple screws or fixing elements, which leads to material waste and increased assembly time.
Innovation Solution
The compressor features two fixing holes on each foot with auxiliary holes of wider diameters, positioned eccentrically to facilitate gasket insertion and prevent rotation, using a neck portion that is outside the force line of action to secure the gasket in place with only two fixing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the foot comprises only fixing holes without auxiliary holes, then the structure is simple, but the gasket fitting becomes difficult during production and assembly
Solution Approach 1:
The foot is segmented into multiple functional zones: fixing holes for secure mounting, auxiliary holes for gasket insertion, and neck portions connecting them. This segmentation allows the gasket to be inserted through the auxiliary hole and retained by the neck portion, making fitting easier without complicating the overall foot structure.
Solution Approach 2:
The auxiliary hole acts as an intermediary element that facilitates gasket insertion. The gasket is first inserted through the auxiliary hole (which has a larger diameter) and then guided through the neck portion into the fixing hole, making the assembly process easier without requiring complex tools or procedures.
2Productivity
If the compressor is fixed by only two holes on opposite feet, then assembly time and material usage are reduced, but the compressor rotates around its center during startup and stopping moments
Solution Approach 1:
The neck portions are positioned asymmetrically relative to the compressor center, specifically outside the circle passing through the fixing holes. This asymmetric positioning creates an offset that generates counteracting moments during rotation, preventing the compressor from rotating around its center during startup and stopping.
Solution Approach 2:
The neck portions are pre-positioned to create counteracting forces before rotation occurs. During startup and stopping moments, when rotational forces are generated, the neck portions outside the force circle create opposing moments that prevent rotation, effectively applying anti-action in advance.
3Stability of the object's composition
If three or four holes are used for fixing the compressor, then rotational stability is improved, but the number of screws and fixing elements increases leading to material loss and time consumption
Solution Approach 1:
The asymmetric positioning of neck portions outside the force circle enables stable two-hole fixing. This asymmetric design creates natural counterbalancing moments that prevent rotation, eliminating the need for additional fixing elements while maintaining stability.
Solution Approach 2:
The neck portions serve a dual function: they guide the gasket during assembly and simultaneously provide rotational stability during operation. This self-service capability eliminates the need for separate stabilizing structures or additional fixing elements.

AI summary
The present invention relates to compressors (1) that comprise a foot (60, 600) facilitating its assembly on the device wherein it will be utilized. In the said compressor (1) besides the fixing holes (71, 72, 701, 702), an adjacent auxiliary hole (81, 82, 801, 802) is formed in order to easily fit in the gasket (3) that attenuates the vibrations.
