Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolytic liquid generation devices face challenges in downsizing electrodes while maintaining their positioning with respect to the housing, leading to instability and potential deformation due to scale accumulation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If electrodes are positioned with respect to the housing by contacting outer edges with the inner face of the housing, then electrode positioning is achieved, but electrode downsizing becomes impossible
Solution Approach 1:
The housing is divided into a positioning member and a housing body. The positioning member is a separate component that can be removed and replaced, allowing the electrode positioning function to be independent from the housing structure. This enables downsizing of electrodes while maintaining positioning capability through the dedicated positioning member.
Solution Approach 2:
The positioning member acts as an intermediary between the electrode and the housing. Instead of directly contacting the housing inner face, the electrode contacts the positioning member, which in turn is positioned within the housing. This intermediary structure enables both electrode downsizing and precise positioning.
2Volume of moving object
If electrodes are downsized, then device compactness is improved, but electrode positioning with respect to the housing becomes unstable
Solution Approach 1:
By separating the positioning function into a dedicated positioning member, the system provides stable positioning for downsized electrodes. The positioning member can be precisely manufactured and fitted into the housing, ensuring consistent electrode positioning even when electrodes are small.
Solution Approach 2:
The positioning member is pre-installed in the housing with precise dimensions and tolerances. This preliminary positioning structure ensures that when downsized electrodes are installed, they are automatically positioned correctly without requiring direct contact with the housing inner face, thereby maintaining positioning stability.
3Object-generated harmful factors
If liquid flows in narrow spaces, then scale accumulation is prevented, but water retention in dead corners increases
Solution Approach 1:
Different regions of the housing have different space characteristics. Narrow spaces are designed between the positioning member and housing to prevent scale accumulation, while ensuring that dead corners are eliminated. The local geometry is optimized to maintain liquid flow in critical areas without creating water retention zones.
Solution Approach 2:
The positioning member is designed to eliminate dead corners where water could be retained. By carefully designing the geometry of the positioning member and its relationship to the housing, spaces that would otherwise trap water are removed, while narrow flow paths are maintained in areas where scale prevention is critical.

AI summary
An electrolytic liquid generation device includes a stacked body in which a conductive membrane is interposed between a cathode and an anode constituting electrodes, an electrolytic part that electrolyzes a liquid, and a housing in which the electrolytic part is disposed. The housing includes a flow path in which a liquid flowing direction intersects a stacking direction of the stacked body. The electrolytic part includes a slot open to the flow path in which a part of the interface between the conductive membrane and the electrode is exposed. In the housing, a positioning member is disposed, and the positioning member positions the electrode.
