Innovation Solution
An apparatus for fixing pressure vessels that includes a separable frame part to support and replace pressure vessels, which also serves as a foothold frame, allowing for efficient fuel supplementation and improved spatial utilization, stability, and safety by enabling the pressure vessels to be densely loaded and securely mounted on construction machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressure vessels are fixed to the construction machine body, then the structure is stable, but the structure becomes complex and design freedom is reduced
Solution Approach 1:
The fixing structure is divided into a separate frame part that can be independently assembled and disassembled from the construction machine body. This segmentation allows the pressure vessels to be mounted on a modular frame rather than directly to the complex machine body, simplifying the overall structure while maintaining stability through dedicated mounting points.
Solution Approach 2:
The frame part serves multiple functions: it supports the pressure vessels, provides a mounting structure, and can be separated for easy replacement. This multi-functionality eliminates the need for separate dedicated fixing mechanisms, reducing structural complexity while maintaining reliability.
2Volume of moving object
If pressure vessels are densely loaded to minimize space, then spatial utilization improves, but the risk of accidents increases
Solution Approach 1:
The frame part is designed as a separate modular structure that can accommodate multiple pressure vessels in a dense arrangement. This segmentation allows for optimized spatial configuration while maintaining proper spacing and structural support for each vessel, reducing accident risk through isolated mounting points.
Solution Approach 2:
The frame part provides a pre-engineered structural framework that anticipates and cushions against potential accidents. By designing the frame with inherent structural integrity and proper mounting configurations before assembly, the system prepares for potential failures, reducing the risk of accidents during operation.
3Productivity
If the frame part is separable to enable easy replacement, then productivity improves, but the structure becomes more complex
Solution Approach 1:
The frame part is designed as a separable module that can be easily detached from the construction machine body. This segmentation enables quick replacement of pressure vessels by simply removing the frame part, significantly improving productivity without requiring complex disassembly procedures.
Solution Approach 2:
The frame part transitions from a fixed state during operation to a movable state during replacement. This dynamic design allows the structure to be stable when needed while enabling easy reconfiguration for maintenance, improving productivity without permanently increasing structural complexity.
4Adaptability or versatility
If pressure vessels are mounted on a separate frame part, then design freedom improves, but the structure becomes more complex
Solution Approach 1:
The separate frame part provides a modular platform that can be independently designed and configured for different pressure vessel arrangements. This segmentation grants design freedom to optimize the mounting configuration without being constrained by the construction machine body's existing structure.
Solution Approach 2:
The frame part serves as a universal mounting platform that can accommodate different configurations of pressure vessels. This multi-functionality provides design freedom for various spatial arrangements while maintaining a relatively simple standardized structure that can be reused across different applications.
