Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor pedestals with transitional attachments are mounted in various modes, leading to potential mounting errors that prevent the compressor from satisfying user needs.
Innovation Solution
Incorporating foolproof structures on the front and rear pedestals of the compressor, ensuring that transitional pedestals can only be mounted in a single mode by using error-proof holes and fasteners, preventing operator errors during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If transitional pedestals are added to enhance compressor stability, then the compressor stability is improved, but the complexity of mounting modes increases leading to mounting errors
Solution Approach 1:
The foolproof structure employs asymmetric geometric design where the protrusion shape on the pedestal does not match the hole shape in the transitional pedestal except for one specific orientation. This asymmetric configuration ensures that the transitional pedestal can only be mounted in the correct orientation, preventing mounting errors while maintaining the stability-enhancing function of the transitional pedestals.
Solution Approach 2:
The foolproof structure acts as an intermediary mechanism between the pedestal and transitional pedestal. This intermediate geometric feature (protrusion-hole interface) mediates the connection by physically allowing assembly only in the correct orientation, thereby resolving the contradiction between providing multiple mounting possibilities for stability and preventing mounting complexity errors.
2Adaptability or versatility
If multiple mounting modes are provided for transitional pedestals, then adaptability to different user needs is improved, but mounting errors increase due to incompatible modes
Solution Approach 1:
The asymmetric foolproof structure provides adaptability through a single correct mounting mode rather than multiple incompatible modes. The geometric design ensures that while there is only one valid orientation, this single mode is sufficient to meet user needs, and the asymmetric constraint prevents the reliability issues associated with multiple incompatible mounting modes.
Solution Approach 2:
Instead of providing multiple mounting modes and hoping users select the correct one, the invention inverts the approach by designing a structure that physically permits only one mounting mode. This inversion transforms the problem from selecting among multiple options to having a single forced correct option, thereby improving reliability while maintaining adaptability.
3Reliability
If foolproof structures are added to pedestals, then mounting error prevention is improved, but the device complexity increases
Solution Approach 1:
The foolproof structure uses simple asymmetric geometric features (a protrusion and corresponding hole) rather than complex mechanical devices. This asymmetric design achieves mounting error prevention through basic geometric constraints, minimizing the increase in device complexity while maximizing reliability improvement.
Solution Approach 2:
The foolproof structure is implemented as a localized geometric feature at the specific interface between the pedestal and transitional pedestal, rather than modifying the entire pedestal structure. This local application of asymmetric geometry provides error prevention exactly where needed without unnecessarily increasing the complexity of the overall pedestal system.

AI summary
A compressor pedestal, a mounting method for the compressor pedestal and a compressor are provided. The pedestal include front pedestal (10), a rear pedestal (20) and transitional pedestals (30). The front pedestal (10) and the rear pedestal (20) are both provided on a compressor shell (40) of the compressor and attached to the respective transitional pedestals (30). Each of the front pedestal (10) and the rear pedestal (20) is provided with a foolproof structure (50) uniquely associated with the respective transitional pedestal (30) so that mounting of the transitional pedestals (30) to the front pedestal (10) and the rear pedestal (20) is limited to a mode of mounting. Through adding the foolproof structures (50), the front pedestal (10) and the rear pedestal (20) can be mounted to the respective transitional pedestals (30) only in a single mode. This can prevent operator errors during mounting, and customers' dimensional requirements can be met, resulting in improved user experience. Further, the pedestal can be mounted more efficiently, and frequent switching between different modes of mounting can be dispensed with.
