Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunshade mounting mechanisms are complex, prone to maintenance issues, and suffer from joint deformation and failure due to environmental exposure, particularly in outdoor use.
Innovation Solution
A simplified sunshade mounting mechanism that uses a first connecting sleeve, a second connecting sleeve, and a pin shaft to achieve rotatable connection between the main rod and the bearing rod, enhancing connection firmness and reducing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two pin shafts are used to connect the frame and bearing rod, then the mounting firmness is ensured, but the structural complexity increases and maintenance becomes tedious
Solution Approach 1:
The patent combines multiple pin shafts into a single integrated pin shaft structure. The first pin shaft connects the first connecting piece to the second connecting piece, while the second pin shaft connects the second connecting piece to the bearing rod, but both are designed as a unified assembly that simplifies installation and maintenance while maintaining the necessary connection firmness.
Solution Approach 2:
The pin shaft assembly serves multiple functions simultaneously: it enables relative rotation between connecting pieces, maintains mounting firmness, and allows angle adjustment between the frame and bearing rod. This multi-functional design reduces the need for separate components and simplifies the overall structure.
2Device complexity
If plastic connecting pieces are used in outdoor environments, then the structure is simple, but the connecting pieces are prone to embrittlement and joint failure
Solution Approach 1:
The patent employs composite material construction for the connecting pieces, combining plastic components with metal reinforcement elements. The plastic portions provide the necessary flexibility and corrosion resistance, while embedded metal components (such as the pin shafts and reinforcing ribs) provide structural strength and resistance to embrittlement, creating a composite structure that leverages the advantages of both materials.
Solution Approach 2:
The connecting pieces feature localized reinforcement where needed - specifically at the joint areas and connection points. The plastic body remains simple and lightweight, but critical regions are strengthened with metal inserts, ribs, or thicker sections to prevent embrittlement and failure under outdoor environmental stress.
3Volume of stationary object
If the frame is located on one side of the bearing rod with a connecting piece at the joint, then the mounting mechanism is compact, but the connection firmness is insufficient under severe environmental conditions
Solution Approach 1:
The patent implements a nested connection structure where the first connecting piece and second connecting piece are interlocked through the pin shaft assembly. The second connecting piece is inserted into the bearing rod structure, and the connecting pieces nest within each other, creating a compact yet firm connection that maximizes connection strength within a limited space.
Solution Approach 2:
Multiple connection functions are merged into a single integrated connecting piece assembly. The first and second connecting pieces work together as a unified structure, with shared pin shafts and interconnected geometry, providing both compactness and enhanced connection firmness through the combined action of multiple structural elements.

AI summary
A sunshade mounting mechanism comprises a first connecting sleeve (3); a second connecting sleeve (4) disposed on the top of the bearing rod (2); a pin shaft (5); the first connecting sleeve (3) is rotatably connected to the second connecting sleeve (4) through the pin shaft (5), and a center line of rotation of the first connecting sleeve (3) intersects with the transverse direction of the main rod (11); the bearing rod (2) has a first through hole (20) for allowing the pin shaft (5) to pass through. In this mounting mechanism, the mounting angle and position of the main rod relative to the bearing rod can be freely adjusted. The pin shaft is allowed to pass through the periphery of the top of the bearing rod on the basis of connecting the first connecting sleeve and the second connecting sleeve. In this way, the connection of the three components, i.e., the first connecting sleeve, the second connecting sleeve and the bearing rod can be achieved by only one pin shaft. The mounting mechanism is simplified, the connection strength can be greatly increased, and the service life is greatly prolonged.
