Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid pressure-feed devices for vehicle body manufacturing lines require multiple pump units to maintain continuous fluid pressure during tank replacement, leading to increased device size and installation space requirements.
Innovation Solution
A compact fluid pressure-feed device configuration that includes a main tank and a sub tank, where the fluid from the main tank is transferred to the sub tank under pressure, allowing continuous fluid pressure feeding during main tank replacement without the need for multiple pump units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two pump units are provided to maintain continuous fluid pressure during tank replacement, then the reliability of continuous fluid feeding is improved, but the device size and installation space increase
Solution Approach 1:
The sub tank is pre-filled with fluid before the main tank is replaced. This preliminary preparation ensures that when the main tank needs replacement, the sub tank already contains sufficient fluid to maintain continuous pressure feeding during the entire replacement operation, eliminating the need for a second pump unit
Solution Approach 2:
The fluid storage system is divided into two separate tanks: a main tank for bulk storage and a sub tank for backup supply. This segmentation allows the system to switch between tanks seamlessly during replacement operations, maintaining continuous fluid pressure without requiring duplicate pump units
2Productivity
If two pump units are provided to maintain continuous fluid pressure during tank replacement, then the productivity of the manufacturing line is improved, but the device complexity increases
Solution Approach 1:
The sub tank is pre-filled with fluid before the main tank is replaced. This preliminary preparation ensures that when the main tank needs replacement, the sub tank already contains sufficient fluid to maintain continuous pressure feeding during the entire replacement operation, eliminating the need for a second pump unit
Solution Approach 2:
The backup fluid storage function is extracted from the pump unit structure and placed into a separate sub tank. This extraction simplifies the pump unit configuration by removing the need for duplicate pumps while maintaining the ability to sustain productivity during tank replacement
3Volume of stationary object
If a single pump unit is used, then the device size is reduced, but the manufacturing line must stop during tank replacement
Solution Approach 1:
The sub tank is pre-filled with fluid before the main tank is replaced. This preliminary preparation ensures that when the main tank needs replacement, the sub tank already contains sufficient fluid to maintain continuous pressure feeding during the entire replacement operation, eliminating the need for a second pump unit
Solution Approach 2:
The sub tank acts as an intermediary fluid reservoir that bridges the gap during main tank replacement. It provides temporary fluid supply to the single pump unit, allowing the manufacturing line to continue operating without interruption while the main tank is being replaced

AI summary
A fluid pressure-feed device (1) includes a main tank (2) and a sub tank (3). The sub tank (3) is connected integrally with an upper portion of a main follower plate (4) that applies pressurizing force to a urethane adhesive (U) inside the main tank (2). A drum pump (8) is provided in an upper portion of a sub follower plate (5) provided in the sub tank (3). While the urethane adhesive (U) is flowing into the sub tank (3) from the main tank (2), the urethane adhesive (U) is fed under pressure from the sub tank (3) to a fluid passage by actuation of the drum pump (8). While the main tank (2) is being replaced, the urethane adhesive (U) inside the sub tank (3) is fed under pressure to the fluid passage by the drum pump (8).
