Embedded Bionic Winch for Self-Lifting Polar Sub-Glacial Probe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winches used for exploring polar sub-glacial lakes contaminate the environment due to drilled channels, making it impossible to obtain original lake water samples.
Innovation Solution
An embedded bionic winch with a modular design, featuring an actuating chamber, power chamber, sensor chamber, cable arranging chamber, and slip ring chamber, which minimizes pollution by using a sheave assembly for load reduction and a tension sensor for controlled cable operation, allowing self-lifting and descending within the probe without external contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ground-based winch with drilled channel is used to lower and lift the probe, then the probe can be deployed and retrieved, but the drilled channel causes pollution to the sub-glacial lake environment and prevents obtaining original lake water samples
Solution Approach 1:
The winch system is nested inside the probe body, with the cable arranging chamber, drum, and cable all contained within the probe structure. This eliminates the need for external ground-based winches and drilled channels, allowing the probe to lower and lift itself without contaminating the sub-glacial lake environment, thus preserving sampling purity.
Solution Approach 2:
The probe is equipped with its own embedded winch system that enables self-lowering and self-lifting operations. The cable is stored and managed within the probe's cable arranging chamber, and the drum is driven by a motor inside the probe, allowing the probe to perform deployment and retrieval functions independently without external equipment that would cause environmental pollution.
2Ease of operation
If the winch components are distributed outside the probe, then the structure is simpler, but the probe cannot achieve self-lifting and descending without external contact
Solution Approach 1:
Multiple functional chambers (cable arranging chamber, actuating chamber, power chamber) are nested concentrically within the probe body along the central axis. The cable passes through these nested chambers in sequence, allowing complex winch functionality to be integrated within the limited probe volume while maintaining operational simplicity.
Solution Approach 2:
The winch system is segmented into distinct functional modules: cable arranging chamber for cable storage and management, actuating chamber with sheave assembly for load reduction, and power chamber with motor for driving the drum. This modular segmentation within the probe enables independent optimization of each component while achieving overall self-lifting capability.
3Volume of moving object
If the cable arranging chamber is designed to minimize volume, then the probe becomes more compact, but the cable management becomes more difficult
Solution Approach 1:
The cable arranging chamber is designed as a concentric nested structure around the central axis of the probe, with the cable wound around a drum that is itself nested within the chamber. This nested arrangement maximizes cable storage capacity within the minimum possible volume, keeping the probe compact while maintaining organized cable management.
Solution Approach 2:
The cable arranging chamber combines multiple functions: cable storage, cable guidance, drum mounting, and tension management. By merging these functions into a single integrated chamber rather than separate components, the design minimizes overall volume while simplifying cable management through centralized control.

Implementation Method 1

Implementation Method 2
the sensor chamber is equipped with a tension sensor, and the tension sensor is used to obtain a tension value of the cable when the cable enters into the cable arranging chamber
