Water Purifier Frame Structure for Upper Module Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water purifiers are prone to deformation and component detachment due to the weight of internal components, particularly during transportation, which can lead to damage and misalignment of parts.
Innovation Solution
A frame structure that supports internal components, including a filter frame and substrate support, to maintain component alignment and prevent deformation, with a substrate assembly positioned below the flow path and valve modules to distribute weight evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are placed at the upper side in the water purifier, then the water purifier can provide purified water directly to the user, but the case is subjected to greater load, increasing the risk of deformation and damage
Solution Approach 1:
The patent divides the case into multiple segments: an upper case portion, a lower case portion, and a reinforcement portion connecting them. This segmentation allows the reinforcement portion to specifically bear the load from upper components while the upper and lower portions maintain their respective functions, resolving the contradiction between component placement and case strength.
Solution Approach 2:
The reinforcement portion acts as a structural counterweight that compensates for the load generated by placing components in the upper portion. By adding this reinforcing structure, the case gains sufficient strength to support upper components without deformation, enabling both direct water provision and case durability.
2Quantity of substance
If the water purifier is subjected to large load during transportation, then it can handle heavy components, but there is a risk that components may become dislodged
Solution Approach 1:
The patent incorporates a support structure that is pre-installed in the case to hold components in place before transportation loads are applied. This preliminary structural arrangement ensures components remain positioned correctly even when heavy loads are subjected during handling and transport.
Solution Approach 2:
The reinforcement portion serves as an intermediary structure between the case and the components. It mediates the load transmission, distributing forces evenly to prevent component dislodgement while maintaining the ability to handle heavy components.
3Productivity
If components are designed to be placed at the upper side, then the water purifier can optimize water flow paths, but the case is subjected to greater load
Solution Approach 1:
The patent applies local quality by adding reinforcement specifically in the portion of the case that experiences load from upper components. Rather than strengthening the entire case uniformly, the reinforcement portion is strategically placed to address the local stress concentration, maintaining water flow efficiency while managing case stress.

AI summary
A water purifier includes: a frame configured to accommodate a filter for filtering water; a flow path module providing a passage for the water to flow and disposed at an upper portion in the frame; a valve module selectively opened and closed to control the flow of water in the flow path module and disposed at a position adjacent to the flow path module; and a substrate assembly for controlling an opening and closing of the valve module. The substrate assembly includes: at least one substrate electrically connected to the valve module; and a substrate support covering at least a portion of the substrate and coupled to the frame to support the at least one substrate. The substrate support is disposed below the flow path module and the valve module and supports at least one of the flow path module and the valve module.
