Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seismic acquisition nodes are bulky, require disassembly for recharging, and have separate housings for digital and analog units, complicating handling and recharging processes.
Innovation Solution
A seismic acquisition system with a common housing that can be configured as either a digital or analog unit, featuring a base and cover design that allows for interchangeable components and simplified manufacturing, including a shared main electronic board and battery pack, with sensors located inside or outside the housing depending on the unit type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate housings are used for digital and analog units, then each unit can be optimized for its specific function, but the device complexity and number of parts increases
Solution Approach 1:
The patent applies universality by designing a common housing that can accommodate both digital and analog seismic acquisition units. The housing includes a standardized battery compartment, circuit board mounting structure, and sensor interface that work for both unit types, eliminating the need for separate housing designs while maintaining functional optimization through configurable electronics.
Solution Approach 2:
The patent merges the housing structures for digital and analog units into a single unified design. The common housing integrates shared components including the battery pack, main circuit board, and structural elements, while allowing for unit-specific configurations through removable or configurable components, thereby reducing the total number of parts.
2Reliability
If digital nodes and analog units use different housings, then each can be designed for its specific recharging process, but the ease of operation deteriorates due to separate recharging stations required
Solution Approach 1:
The common housing incorporates a universal power interface and battery configuration that allows both digital and analog units to be recharged using the same recharging station. The standardized electrical connections and power management circuitry enable a single recharging infrastructure to serve both unit types, improving ease of operation while maintaining reliable charging processes.
3Productivity
If seismic nodes are made compact with smaller battery, then the productivity and ease of deployment improves, but the duration of action decreases due to limited battery capacity
Solution Approach 1:
The patent applies dynamics by implementing a configurable power management system that can adapt battery usage based on operational requirements. The system includes adjustable power consumption modes, dynamic voltage regulation, and intelligent power allocation that optimizes battery life based on whether the unit is in digital or analog mode, thus extending operational duration while maintaining compact size.
