Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electroless plating techniques require complex facilities, large amounts of processing solution, and often result in suboptimal quality due to solution runoff and inadequate solution application, as well as issues with bubble removal and structural vibration.
Innovation Solution
A surface treating apparatus with a transport hanger and tank body design that includes a liquid receiving part, a liquid retaining part, and a liquid outflowing part, where the outflowing part is projected to apply processing solution directly to the workpiece, and a guide rail system for controlled movement to remove bubbles and reduce vibration, allowing for efficient solution circulation and minimized solution usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the technique of JP-B-3115047U, JP-A-2006118019, or JP-A-2004339590 is adopted to prevent plate-like work from contacting side walls by causing vertical flow or shaking the work, then the work can be prevented from contacting side walls, but the processing solution runs down the side walls inside the tank, resulting in poor plating quality and requiring a mass of processing solution
Solution Approach 1:
The invention extracts the harmful function of solution running down the side walls by introducing a liquid receiving part that collects excess solution before it can contaminate the plating area. The liquid outflowing part then redirects this collected solution to flow downward toward the treatment object, converting a harmful effect into a useful one.
Solution Approach 2:
The liquid receiving part acts as an intermediary between the liquid retaining part and the treatment object. It collects processing solution that would otherwise run down the side walls and redirects it through the liquid outflowing part, serving as a mediator that prevents contamination while maintaining solution utilization.
2Reliability
If a rise-and-fall mechanism is used to dip the treatment object into processing solution stored in a tank, then electroless plating can be performed, but the facility becomes more complex and larger, and a mass of processing solution is required
Solution Approach 1:
The invention replaces the static rise-and-fall dipping mechanism with a dynamic liquid flow system. The processing solution is actively circulated from the liquid retaining part through the liquid outflowing part to the treatment object, eliminating the need for mechanical dipping motion while maintaining effective solution application.
Solution Approach 2:
The invention substitutes the mechanical rise-and-fall dipping system with a fluid circulation system. Instead of mechanically moving the treatment object into and out of the solution, the system uses pumped liquid flow to deliver solution to the treatment object, replacing mechanical motion with fluid dynamics.
3Productivity
If the treatment object is temporarily made to move over a difference in level to drain off liquid by making an impact, then liquid can be drained, but it is not possible to drain off liquid surely
Solution Approach 1:
The invention provides continuous liquid drainage through the liquid receiving part that constantly collects excess processing solution from the liquid retaining part. This continuous collection and redirection of solution ensures reliable liquid removal without relying on intermittent impact actions, maintaining steady-state operation.
