Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If manual lifting is used to dismount and mount the high temperature and high pressure load sensor, then the sensor can be replaced, but the operation is risky and difficult due to the sensor's weight and limited space
Solution Approach 1:
A lifting device is introduced as an intermediary tool between the operator and the heavy load sensor. The device includes a lifting seat with a suction cup that attaches to the sensor bottom surface, allowing mechanical assistance for lifting and positioning the heavy sensor without direct manual handling, thus resolving the contradiction between sensor replacement capability and ease of operation
Solution Approach 2:
The manual mechanical lifting operation is replaced with a mechanical lifting device that uses suction force and mechanical structures (lifting seat, support plate, alignment device) to handle the sensor. This substitution eliminates the need for operators to manually lift and align the heavy sensor, improving ease of operation while maintaining sensor replacement capability
2Ease of operation
If the high temperature and high pressure load sensor is held by unstable suction force, then the sensor can be positioned, but the sensor is difficult to dismount and has high risk of abrupt falling
Solution Approach 1:
The lifting device incorporates a mechanical support structure with a support plate and alignment device that provides preliminary mechanical support before the sensor is fully secured. This cushioning mechanism prevents abrupt falling by ensuring the sensor is mechanically supported even if suction force fails, thus improving reliability while maintaining positioning capability
Solution Approach 2:
The lifting device acts as an intermediary between the suction cup and the sensor, providing mechanical support and stability. The device includes structural elements like the lifting seat, support plate, and alignment device that ensure stable positioning and prevent abrupt falling, resolving the contradiction between ease of positioning and operational reliability
3Measurement precision
If precise row lines are densely arranged on the triaxial chamber base, then measurement accuracy is improved, but alignment of bolt holes and stop pin holes becomes difficult due to limited operation space
Solution Approach 1:
An alignment device is introduced as an intermediary tool that bridges the gap between the dense row lines and the hole alignment process. The device includes alignment marks and mechanical guides that simplify the complex task of aligning bolt holes and stop pin holes with the precise row lines, resolving the contradiction between measurement precision and ease of operation
Solution Approach 2:
The alignment device incorporates pre-marked alignment features and guides that are prepared in advance. The alignment marks on the lifting device and the mechanical guides are designed to automatically align with the row lines before the actual mounting operation, making the hole alignment process easier while maintaining precision
