Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pressure detection device's pressure detecting property varies due to variations in mounting work by operators, causing inconsistent pressure readings when replacing the flow passage unit, despite the same pressure being applied by both used and new units.
Innovation Solution
Incorporating a sliding layer with a fluororesin material on the pressure detecting and transmitting surfaces to maintain a constant state of contact, ensuring consistent pressure detection even with variations in mounting work, and using a nut-based mounting mechanism to gradually bring the surfaces into contact, preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the flow passage unit is removably mounted to enable replacement, then productivity is improved by avoiding cleaning time, but manufacturing precision deteriorates due to variations in mounting work causing inconsistent pressure detection
Solution Approach 1:
A sliding layer is introduced as an intermediary between the pressure transmitting surface and the pressure detecting surface. This sliding layer mediates the contact interaction, allowing the flow passage unit to be removably mounted for quick replacement while maintaining consistent pressure detection. The sliding layer compensates for mounting variations by providing a standardized contact interface.
Solution Approach 2:
The sliding layer changes the friction parameter between the pressure transmitting surface and pressure detecting surface. By reducing friction and enabling smooth relative movement, the system allows for consistent contact pressure regardless of mounting variations, thus maintaining manufacturing precision while enabling rapid replacement.
2Reliability
If the pressure transmitting surface is brought into contact with the pressure detecting surface through mounting work, then the pressure detection function is achieved, but reliability deteriorates due to variations in mounting work causing detection property changes
Solution Approach 1:
The sliding layer serves as a mediator that standardizes the contact interface between the pressure transmitting surface and pressure detecting surface. It ensures reliable and consistent pressure detection by providing a uniform friction characteristic, while still allowing operators to perform mounting work with natural variability.
Solution Approach 2:
The sliding layer enables the system to self-adjust to mounting variations. As the flow passage unit is mounted, the sliding layer automatically compensates for minor positioning differences through its low-friction properties, ensuring consistent detection without requiring precise manual alignment.
3Strength
If the pressure transmitting surface and pressure detecting surface are brought into contact, then pressure transmission is achieved, but object-generated harmful factors increase due to potential damage from improper mounting
Solution Approach 1:
The sliding layer provides beforehand cushioning by creating a low-friction interface that prevents sudden impacts and shocks during mounting. This protective layer cushions the pressure transmitting surface and pressure detecting surface against damage from improper or forceful mounting operations.
Solution Approach 2:
The sliding layer acts as a protective intermediary between the pressure transmitting surface and pressure detecting surface. It distributes contact forces evenly and prevents concentrated stresses that could cause surface damage, thereby protecting the critical detection surfaces during mounting and operation.
