Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor packaging methods fail to stabilize compressors without end cap fixing boards and horizontal set type compressors during transportation, leading to potential damage from vertical vibration and waggling.
Innovation Solution
A packaging apparatus using stepped fitting portions on a lower plate with paper pipes supporting the end caps, an intermediate plate with recesses for the fixing boards to prevent rotation, and additional paper pipes between plates to absorb vibrations and protect connection terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If compressors are packaged using conventional methods without end cap fixing boards, then the packaging structure is simpler, but the compressors become unstable during transport and risk damage from vertical vibration or waggling
Solution Approach 1:
The patent introduces an intermediary fixing board structure that can be attached to the end caps of compressors. This fixing board acts as a mediator between the compressor and the packaging structure, providing stable attachment points that prevent vertical vibration and waggling during transport, thereby resolving the contradiction between structural simplicity and reliability
Solution Approach 2:
The patent applies preliminary action by pre-attaching fixing boards to the end caps of compressors before packaging. This preliminary preparation ensures that the compressors have stable attachment points ready for packaging, eliminating the need for complex packaging structures while maintaining reliability during transport
2Device complexity
If compressors are pinched between upper and lower plates without proper fixing structures, then the packaging apparatus is simpler, but the compressors cannot be stabilized and remain unstable during transport
Solution Approach 1:
The patent segments the packaging apparatus into multiple functional components: upper plate, lower plate, intermediate plate with insertion holes, and fixing boards. This segmentation allows each component to perform its specific function - the fixing boards provide stability while the plates provide containment, resolving the contradiction between simplicity and stability
Solution Approach 2:
The intermediate plate with insertion holes acts as an intermediary structure between the upper and lower plates. It provides additional support and stability points for the compressors, enabling stable packaging without requiring the upper and lower plates to directly bear the full weight, thus maintaining apparatus simplicity while improving stability
3Adaptability or versatility
If fixing boards are provided on peripheral side surfaces of compressor bodies, then horizontal set type compressors can be packaged, but the compressors still waddle and weld portions are damaged by vertical vibration
Solution Approach 1:
The patent adds a vertical dimension to the fixing structure by attaching fixing boards to the end caps (vertical orientation) in addition to the horizontal fixing boards on peripheral surfaces. This multi-dimensional approach provides both horizontal and vertical stabilization, preventing waggling and vertical vibration damage while maintaining compatibility with horizontal set type compressors
Solution Approach 2:
The patent uses composite fixing structures combining different types of fixing boards (end cap fixing boards and peripheral fixing boards) to create a comprehensive stabilization system. This composite approach addresses multiple vibration directions simultaneously, protecting weld portions from damage while maintaining packaging adaptability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures stable positioning and protection of compressors during transport, preventing damage from vibrations and waggling by distributing loads and absorbing shocks with paper pipes, while also preventing rotation and terminal exposure.
Implementation Method 1
first paper pipes fitted to the stepped fitting portions... second paper pipes that are covered on the upper end caps... third paper pipes disposed between the intermediate plate and the upper plate... absorb vibrations and protect connection terminals
