Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Piston compressors used in mobile applications are bulky and heavy due to the need for separate compressed air storage tanks, making them less portable and more costly.
Innovation Solution
Integrating the compressed air storage tank within the crankcase of the compressor, utilizing the space around the drive shaft to eliminate the need for a separate tank, resulting in a more compact and lightweight design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a separate compressed air storage tank is used, then the storage volume can be sufficient, but the weight and size increase significantly
Solution Approach 1:
The patent merges the compressed air storage tank with the crankcase by defining the storage tank as an integral part of the crankcase structure. The crankcase is designed with a hollow body that accommodates the drive shaft, and the storage tank is formed within this hollow space, eliminating the need for a separate storage container. This integration achieves both sufficient storage volume and reduced weight by combining two previously separate components into one unified structure.
Solution Approach 2:
The patent applies the nesting principle by placing the compressed air storage tank inside the hollow body of the crankcase. The storage tank is nested within the existing crankcase structure, utilizing the available space efficiently. This allows the storage tank to be contained within the crankcase boundaries, achieving compact integration without requiring additional external space or increasing overall weight.
2Quantity of substance
If a separate compressed air storage tank is used, then the storage capacity is adequate, but the number of components and assembly complexity increase
Solution Approach 1:
The patent combines the storage tank and crankcase into a single integrated component. The crankcase is designed with a hollow body that serves as the storage tank, eliminating the need for separate storage container components. This merging reduces the total number of parts, simplifies assembly procedures, and eliminates the need for separate bearing adjustments while maintaining adequate storage capacity.
3Volume of moving object
If the compressor is made more compact for portability, then the size reduces, but the storage volume may be limited
Solution Approach 1:
The patent utilizes the nesting principle by placing the storage tank inside the hollow crankcase body. This allows the storage volume to be accommodated within the existing compact crankcase structure without increasing the overall compressor size. The hollow body of the crankcase serves as the storage tank, enabling sufficient storage capacity while maintaining a compact, portable form factor.
Solution Approach 2:
The patent optimizes space utilization by designing the storage tank to extend in multiple dimensions within the hollow crankcase body. The storage tank is configured to utilize the available volume efficiently in radial, axial, and angular directions, maximizing storage capacity within the compact crankcase boundaries. This dimensional optimization allows adequate storage volume without increasing the overall compressor size.
