Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in individually conveying Fabry-Perot interference filter chips is to ensure stable detachment without altering their posture or position, as existing suction methods often result in breakage or unstable release.
Innovation Solution
A suction method utilizing a suction collet with specifically designed contact surfaces and guide portions that target the electrode terminals of the Fabry-Perot interference filter, allowing controlled suction and release while minimizing contact with the membrane structure, thereby preventing breakage and ensuring stable detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If suction is applied to the entire surface of the Fabry-Perot interference filter, then the suction force is sufficient to hold the filter, but the membrane structure may break due to excessive load
Solution Approach 1:
The suction method extracts the suction action from the entire filter surface and concentrates it only on the electrode terminals. The suction collet is designed with contact portions that selectively contact only the electrode terminals, excluding the membrane structure from the suction zone. This extraction principle allows sufficient suction force to be applied to the rigid electrode terminals while completely avoiding application of force to the fragile membrane structure, thereby resolving the contradiction between holding force and membrane integrity.
Solution Approach 2:
The suction collet is designed with differentiated contact portions: first contact surfaces for the first electrode terminals and second contact surfaces for the second electrode terminals, while deliberately excluding the membrane structure area. This local quality differentiation ensures that suction force is concentrated on the robust electrode terminals that can withstand the force, while the membrane structure remains free from mechanical load, thus resolving the contradiction between adequate suction force and membrane protection.
2Area of stationary object
If the suction collet contacts the membrane structure during suction, then the suction area is increased, but the membrane structure may break due to direct contact
Solution Approach 1:
The suction method extracts the membrane structure from the suction contact zone entirely. The suction collet's contact portions are specifically designed to target only the electrode terminals, with the opening positioned to exclude the membrane structure. This extraction ensures that while suction is effectively applied to the electrode terminals, the membrane structure is completely avoided, preventing breakage while maintaining adequate suction area on the robust terminals.
Solution Approach 2:
The suction collet design implements local quality by creating distinct contact zones: contact surfaces that engage with electrode terminals and a deliberate exclusion zone for the membrane structure. The opening of the suction collet is positioned and sized to allow suction force to concentrate on the electrode terminals while the membrane structure falls outside the suction influence zone, thus increasing effective suction area on suitable surfaces while protecting the membrane.
3Loss of time
If suction is released abruptly, then the detachment process is fast, but the posture and position of the filter may change uncontrollably
Solution Approach 1:
The suction method applies preliminary action by first establishing stable contact with the electrode terminals before full suction engagement. The suction collet is positioned and contacted in a controlled sequence, allowing the electrode terminals to be firmly grasped before suction force is fully applied. This preliminary stable contact ensures that when suction is subsequently released, the filter maintains its posture and position, enabling fast yet controlled detachment without uncontrollable movement.
4Strength
If the suction collet is designed to contact only the electrode terminals, then the membrane structure is protected, but the suction force may be insufficient to hold the filter
Solution Approach 1:
The suction method extracts the suction function from the membrane structure and relocates it entirely to the electrode terminals. The suction collet is designed with contact surfaces that selectively engage only with the electrode terminals, which are robust structures capable of withstanding suction forces. This extraction concentrates the full suction force on the strong electrode terminals, providing sufficient holding force while completely avoiding the fragile membrane structure, thus simultaneously achieving both adequate force and membrane protection.

Function Achieved in This Case
The method enables stable and controlled detachment of Fabry-Perot interference filters by limiting the suction range to the electrode terminals, reducing the load on the membrane structure, and regulating the filter's posture, thus preventing breakage and ensuring reliable handling.
