Fluid Supply Device Intake Port Redesign for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of fluid supply devices for fluid chromatographs is limited by the need to integrate a heat dissipation intake port, which restricts designability when placed on the side or front, affecting the device's aesthetic and functional design.
Innovation Solution
A fluid supply device with a storage container featuring a front intake port that intersects with the device's surface direction, combined with a heat dissipation system and a filter-guiding mechanism, allowing for improved heat dissipation and reduced visibility of the intake port, enhancing designability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the intake port is provided in the side surface of the casing, then heat dissipation is effective, but the device requires additional space sidewardly and restricts provision of another appliance
Solution Approach 1:
The intake port is repositioned from the side surface to the front portion of the casing, changing the spatial dimension of heat intake. This allows heat dissipation to occur through the front direction rather than requiring side space, thereby resolving the contradiction between effective heat dissipation and space availability for additional appliances.
2Ease of manufacture
If the intake port is provided in the front portion of the casing, then designability of the front portion is improved, but the intake port becomes visible and may affect aesthetics
Solution Approach 1:
A cover member is introduced as an intermediary element that conceals the intake port from the front view while allowing air to pass through. This mediator resolves the contradiction by maintaining the functional benefits of front-positioned intake port for designability while hiding it to preserve aesthetic appearance.
3Ease of operation
If the pump head is arranged forwardly of the casing, then accessibility is improved, but active cooling requires forming a rearward flow of gas inside the casing
Solution Approach 1:
The gas flow direction is inverted from the conventional forward flow to a rearward flow inside the casing. This inversion allows the pump head to be positioned forwardly for better accessibility while still achieving effective cooling by directing cooled air toward the heat-generating components from the rear.
Applied Scientific Principles
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 enhances designability by hiding the intake port from the front view while ensuring effective heat dissipation and preventing particle adherence, thus improving both aesthetics and functionality.
Implementation Method 1
a heat dissipation device that dissipates heat generated from the pump device to outside of the storage container together with gas inside of the storage container
Implementation Method 2
gas introduced into the storage container through the intake port is guided to the filter, whereby particles or the like are prevented from adhering to the pump device stored in the storage container

AI summary
A fluid supply device for a fluid chromatograph includes a storage container, a pump device, a filter, a guide and a heat dissipation device. The pump device supplies a mobile phase to a column. The storage container stores the pump device and the filter and has an intake port. The guide guides gas that has been introduced into the storage container through the intake port to the filter. A heat dissipation device dissipates heat generated from the pump device to the outside of the storage container together with the gas inside of the storage container. The storage container includes a door having a front surface directed forwardly of the fluid supply device. The intake port is provided at the door to be directed sidewardly of the fluid supply device.
