Solution Overview

Problem

Conventional filter apparatuses for chemical solutions require complex air releasing operations that compromise operability and compactness due to the need for physical space and manual manipulation in limited environments, leading to reduced workability and increased risk of piping component damage.

Innovation Solution

A filter apparatus design featuring a holder with a rotating filter body and engaging mechanisms that allow air release without lifting the filter body from the holder, enabling lateral access and reducing the size of the apparatus, thus enhancing operability and preventing piping component damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the filter body is removed from the holder to perform air releasing operation, then air can be released from the filter body, but the apparatus size increases and operability deteriorates due to limited physical space

Engineering Contradiction:
Improveair releasing functionVSAvoidoperability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The filter body is designed to be rotatable within the holder, transitioning between filtering position and air releasing position, with dynamic engagement and disengagement from different engaging portions to enable flexible operational states

Inventive Principle:
Principle #15Dynamics

2Reliability

If the filter body is lifted up and rotated by 180° for air releasing operation, then air can be released, but the operation complexity increases and workability deteriorates

Engineering Contradiction:
Improveair releasing functionVSAvoidoperation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The holder is pre-equipped with multiple engaging portions positioned to automatically engage with the filter body at predetermined positions (filtering position and air releasing position), eliminating the need for manual rotation and lifting operations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The filter body automatically engages with the appropriate engaging portion based on its orientation, with the system self-regulating to maintain the filter body in the correct position without requiring manual intervention for positioning

Inventive Principle:
Principle #25Self-service

3Reliability

If the filter body is rotated by 180° for air releasing operation, then air can be released, but piping components may be damaged due to stress and twisting

Engineering Contradiction:
Improveair releasing functionVSAvoidpiping component damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The filter body rotates in place within the holder rather than being lifted and repositioned, with flexible piping connections that accommodate the rotation without excessive stress or twisting

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The holder acts as an intermediary structure that provides a controlled rotation path and supports the filter body during orientation changes, preventing direct stress transmission to the piping components

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

[Summary] [Problems] To provide a filter apparatus improved in operability and maintainability during an air releasing operation for a filter apparatus by promoting a reduction in the size of a filter apparatus capable releasing air for a chemical solution. [Means for solving the problems] The holder (3) of a filter apparatus (1) comprises a front panel (5) and a rear panel (7) vertically positioned parallel with each other. The front panel (5) and the rear panel (7) are connected to each other through a connection portion capable of forming one of the upper panel (9), the side panel (109), and the bottom panel (209) of the holder. A center cutout (11) for rotatably engaging the fluid inlet of the filter body of the filter is formed in the front panel (5) of the holder (3) at a position corresponding to the fluid inlet of the filter body when the filter body is assembled with the holder (3). The fluid inlet (3) for injecting a chemical solution to be filtrated through the filter body (13) is formed in the filter body (13) at a position where the rotating axis is located. A fluid outlet (17) for feeding the filtrated chemical solution from the filter body (13) to a nozzle and discharging the air accumulated in the filter body (13) is formed in the filter body at a position near its circumference.
