AI Technical Summary

Benefits of technology

This patented technology allows for easy removal from electronic devices without causing any harm or damaging them during their use. It also simplifies the way they are designed by allowing the materials used thereto have specific shapes that allow certain parts thereof to be easily released with minimal effort compared to other designs like springs. Additionally, the design ensures stability over time due to its closed loop controlled thermal driving unit (Heated Drives) fused together. Overall, these technical improvements make the releasing process more efficient and effective than existing methods such as spring mechanisms.

Problems solved by technology

The technical problem addressed by this patented method relates to separating spatially deployed structure from terrestrial environments that may be affected due to impact or fragmentation caused by conventional methods like rocket propellants used for launching vehicles on Earth' s surface. Existing systems have their own drawbacks including complexity, weightiness, high maintenance costs, safety concerns associated with use thereof, environmental hazards related to potential contamination issues, etc., making them difficult to apply even at large scales where they could potentially harm human health.

Abstract

The invention relates to a large load-bearing compressed shape-memory polymer composite material release mechanism for space, relating to a polymer composite material release mechanism. In order to solve the problem that the traditional release mechanism produces an impact during the space release process, and the explosion fragments are easy to damage the surrounding equipment. The invention includes a heating drive device and a main structure connector made of shape memory polymer composite material and a release mechanism connector; the main structure connector includes a flanged connection plate and an outer sleeve of the release mechanism; the release mechanism connector includes a connecting chassis and the inner sleeve of the release mechanism; the outer sleeve of the release mechanism is sleeved on the outside of the inner sleeve of the release mechanism, and an external force is applied to make the outer sleeve of the release mechanism and the inner sleeve of the release mechanism relatively fixed; the heating drive device is heated, and the shape memory polymer composite material The outer sleeve of the release mechanism made of high-quality material and the inner sleeve of the release mechanism return to the straight cylinder state after being heated, and are separated from each other to realize the release. The invention is applicable to the release field of aerospace equipment and the like.
