Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic rods suffer from vibration due to gaps between internal tube bodies and struggle to provide stable, lasting resistance for load-bearing applications, especially in outdoor environments.
Innovation Solution
A telescopic rod with an elastic damping structure, featuring a damping member and an elastic member, where the elastic force drives the inner and outer tubes to fit closely, eliminating gaps and providing stable friction damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a damping plate is used to eliminate gaps between tubes, then gap jitter is reduced, but the plastic damping plate deteriorates quickly due to fatigue and temperature, losing its resistance capability
Solution Approach 1:
The patent uses a composite structure combining a metal elastic member (spring) with a plastic damping plate. The metal spring provides durable elastic force while the damping plate eliminates gaps, allowing each material to contribute its strengths and overcome individual weaknesses
Solution Approach 2:
The patent changes the material parameter of the elastic member from plastic to metal, fundamentally improving fatigue resistance and temperature stability while maintaining the gap-elimination function through the combined structure
2Reliability
If a spring is used to provide stable elastic force, then resistance stability is improved, but the spring occupies space and creates gaps between tubes, increasing vibration
Solution Approach 1:
The patent merges the spring and damping plate into a single integrated elastic damping structure where the spring and damping plate work together synergistically - the spring provides elastic force while the damping plate maintains contact between tubes, eliminating the need for separate components
3Stability of the object's composition
If a plastic damping plate is used for damping, then gap elimination is achieved, but the fatigue strength of plastic is poor causing quick deterioration of resistance
Solution Approach 1:
The patent combines metal and plastic materials in the elastic damping structure, using metal for the elastic member to provide high fatigue strength and plastic for the damping plate to provide gap elimination and damping, creating a composite structure that overcomes the limitations of single materials
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively eliminates vibration caused by matching gaps, provides durable and stable support for photographic equipment, and maintains performance across varying temperatures and environments.
Implementation Method 1
one end of the elastic member may abut against the damping member, and the other end may abut against the inner wall of the inner tube. In some embodiments, the elastic force of the elastic member may drive the inner tube, the damping member and the outer tube to fit closely
Implementation Method 2
the damping member and the inner wall of the outer tube form friction damping, the inner tube may slide along the inner wall surface of the outer tube through the damping member and may maintain in the relative position after sliding through the damping member

AI summary
A telescopic rod with an elastic damping structure comprises at least two sections of tube which are sleeved in sequence and arranged between two adjacent sections of the tube. The two adjacent sections include an inner tube and an outer tube, and the elastic damping structure comprises a damping member and an elastic member. The damping member is arranged between the end of the inner tube and the inner wall of the outer tube, one end of the elastic member abuts against the damping member, and the other end abuts against the inner wall of the inner tube, and the elastic force of the elastic member drives the inner tube, the damping member and the outer tube to fit tightly.
