Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deploying microchips in downhole drilling environments are time-consuming, prone to human error, and difficult to monitor, especially due to the miniaturized size and quantity of microchips.
Innovation Solution
A microchip deployment mechanism featuring a spherical valve with a rotatable valve body that includes a microchip pocket, allowing for controlled deployment of microchips into the drilling fluid pipe, maintaining high pressure and enabling autonomous operation based on user-programmed schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual deployment of microchips is used, then deployment can be performed with simple equipment, but the process is time-consuming and prone to human error
Solution Approach 1:
The spherical valve is segmented into multiple pockets, each capable of holding and deploying individual microchips. This segmentation allows the system to handle multiple chips through a single automated mechanism, improving productivity while maintaining manageable complexity
Solution Approach 2:
The spherical valve automatically rotates to position pockets for receiving or deploying chips based on flow conditions, eliminating the need for complex external control mechanisms. The system serves itself by using the existing fluid flow to drive the rotation and deployment process
2Quantity of substance
If microchips are deployed in large quantities, then data collection capability is improved, but monitoring the number of deployed microchips becomes difficult
Solution Approach 1:
The system provides visual feedback through the position of the spherical valve and pocket orientation. By observing which pockets are receiving or deploying chips, operators can monitor the deployment process and count deployed microchips without direct intervention, solving the monitoring difficulty while maintaining high quantity deployment
3Productivity
If microchips are introduced rapidly into the fluid system, then deployment efficiency is improved, but control over drop orientation and rate is lost
Solution Approach 1:
The spherical valve dynamically adjusts its rotation speed and pocket positioning based on the desired deployment rate. The system transitions from static, manual deployment to dynamic, controlled rotation that can be adjusted to achieve optimal deployment rates while maintaining proper chip orientation through the programmed rotation sequence
4Ease of manufacture
If the microchip pocket is always open for receiving chips, then chip loading is simplified, but high pressure within the pipe is compromised
Solution Approach 1:
The spherical valve performs periodic rotation, opening the pocket to the input opening only during specific rotational phases when chips need to be loaded. During other phases, the pocket is sealed or positioned away from the opening, maintaining pressure integrity. This periodic opening and closing resolves the contradiction by providing controlled access rather than continuous openness

AI summary
A microchip deployment system for a well includes a drilling fluid pump, a drilling fluid pipe extending from the drilling fluid pump into the well, and a microchip deployment mechanism provided on the drilling fluid pipe. The microchip deployment mechanism comprises a housing and a spherical valve. The housing has an input opening and an output opening. The spherical valve is rotatably arranged within the housing, and the spherical valve comprises a microchip pocket. The spherical valve is rotatable within the housing from a receiving position to a deploying position, wherein the microchip pocket is proximate to the input opening when in the receiving position, and wherein the microchip pocket is proximate to the output opening when in the deploying position.
