Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional poles lack effective shock absorption, leading to discomfort and potential injury during outdoor activities, and existing shock absorption mechanisms are either bulky, costly to manufacture, or compromise the strength and stability of the pole.
Innovation Solution
A compact leg assembly with a support leg, tray, and connecting sleeve, featuring elastic limiting clamps and a shock absorption spring, which allows the pole body to move relative to the support leg, providing effective shock absorption without compromising the pole's strength or requiring hole formation in the tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an elastic mechanism is arranged at the handle for shock absorption, then shock absorption function is provided, but the pole becomes bulky and heavy
Solution Approach 1:
The shock absorption mechanism is relocated from the handle area to the lower end of the pole tube, utilizing the vertical dimension and space at the pole's endpoint. This dimensional relocation allows the shock absorption spring to be positioned where it can effectively absorb impact forces without adding bulk to the handle area, thereby maintaining a lightweight and compact pole design.
Solution Approach 2:
The shock absorption spring is nested within the pole tube structure itself, utilizing the internal space of the tube. The spring is positioned within the hollow cavity of the pole tube, and the support leg extends through this nested arrangement. This nesting approach allows the shock absorption mechanism to be integrated into the existing pole structure without adding external bulk or significant weight.
2Object-affected harmful factors
If an elongated hole is formed at the lower end of the tube for shock absorption mechanism, then shock absorption function is provided, but the manufacturing complexity and cost increase
Solution Approach 1:
The pole structure is segmented into distinct functional components: the pole tube, the support leg, and the shock absorption spring. The support leg is a separate component that connects to the pole tube through a simple insertion and locking mechanism, rather than requiring the tube itself to be modified with holes. This segmentation allows each component to be manufactured independently using standard processes, simplifying production.
Solution Approach 2:
The shock absorption mechanism is extracted from the pole tube structure itself and implemented as a separate assembly involving the support leg and spring. Instead of modifying the tube with elongated holes, the support leg is inserted into the tube and secured with a pin, with the spring positioned between the support leg and tube end. This extraction approach eliminates the need for complex hole-forming operations on the tube.
3Object-affected harmful factors
If an elongated hole is formed at the lower end of the tube for shock absorption mechanism, then shock absorption function is provided, but the tube strength is reduced
Solution Approach 1:
The pole structure is segmented into distinct functional components: the pole tube, the support leg, and the shock absorption spring. The support leg is a separate component that connects to the pole tube through a simple insertion and locking mechanism, rather than requiring the tube itself to be modified with holes. This segmentation allows each component to be manufactured independently using standard processes, simplifying production.
Solution Approach 2:
Instead of creating holes in the tube to accommodate the shock absorption mechanism, the approach is inverted: the support leg is inserted into the tube, and the connection is secured from the inside using a pin through the tube wall. This inversion maintains the integrity of the tube structure, as the pin creates only small connection holes rather than large elongated holes, preserving the tube's strength.
4Object-affected harmful factors
If a drawstring and spring are used to connect pole sections for shock absorption, then shock absorption function is provided, but the connection firmness and stability decrease
Solution Approach 1:
The support leg is pre-positioned within the pole tube, and the pin is prepared for insertion. When assembled, the pin is inserted through the tube wall to secure the support leg in place before the shock absorption spring is engaged. This preliminary securing action ensures that the support leg cannot separate from the tube, providing firm and stable connection while maintaining shock absorption capability.
Solution Approach 2:
The connection mechanism merges multiple functions into a single pin component: it secures the support leg to the tube, maintains the structural integrity of the pole, and allows the shock absorption spring to function. This merged approach eliminates the need for separate drawstrings and multiple connection elements, providing a more reliable and stable connection.

AI summary
A leg assembly, and a shock absorption mechanism for a pole are provided. The shock absorption mechanism comprises a pole body and a leg assembly, wherein the leg assembly comprises a support leg, a tray surrounding the support leg, and a connecting sleeve for connecting the pole body inserting from the top of the support leg. When a bottom of the pole body is inserted into the connecting sleeve and tightly resists against the elastic limiting clamps, the elastic limiting clamps will be pushed outward and limited in the guiding slots of the support leg, so that the connecting sleeve with the pole body can move upward and downward relative to the support leg. There is a mounting space for the shock absorption spring between the support leg and the connecting sleeve, and the support leg has a trend of moving downward due to resistance from the shock absorption spring.
