Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing umbrellas are inefficient and inconvenient to unfold and fold due to the use of ropes, and they lack adjustable shading angles, which limits their effectiveness in providing optimal shading at different times and positions.
Innovation Solution
An angle-adjustable umbrella without ropes, featuring a sliding block on a column, a transverse rod, a tilted rod, and a clutch mechanism that allows for easy unfolding and folding, as well as adjustable shading angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ropes are used to fold or unfold umbrellas, then the umbrella can be supported and folded, but it is time-consuming and labor-consuming, low efficient and inconvenient to use
Solution Approach 1:
The patent removes the rope component entirely from the umbrella structure. Instead of using ropes to tie and unfold the umbrella, the invention employs a direct mechanical linkage system where the transverse rod connects the tilted rod to the sliding block, enabling rope-free operation that eliminates the time and effort required to tie and untie ropes.
Solution Approach 2:
The patent implements a dynamic unfolding mechanism where the sliding block moves along the column to directly drive the transverse rod and tilted rod assembly. This dynamic mechanical system allows the umbrella to unfold and fold smoothly through the movement of the sliding block, replacing the static rope-tying process with an efficient mechanical motion system.
2Reliability
If ropes are used to fold or unfold umbrellas, then the umbrella can be supported, but the strength and length of the rope cannot be accurately controlled and the whole product cannot be used due to deficiencies in strength and size of the rope
Solution Approach 1:
The patent eliminates the rope component that caused reliability and control issues. By removing the rope and replacing it with a rigid transverse rod connected to the sliding block through a clutch mechanism, the invention ensures consistent structural support without the variability and control difficulties associated with rope strength and length.
Solution Approach 2:
The patent introduces the transverse rod as an intermediary mechanical element between the sliding block and the tilted rod. This intermediary component provides reliable and consistent support, replacing the unreliable rope system while simplifying the control mechanism through direct mechanical coupling rather than rope tension control.
3Adaptability or versatility
If the umbrella is always supported at a same angle, then the structure is simple, but a good shading effect cannot be achieved since the irradiation angle of solar rays is different at different positions and different times
Solution Approach 1:
The patent implements a dynamic angle adjustment mechanism where the clutch mechanism allows the transverse rod to rotate relative to the sliding block. This enables the umbrella frame to be adjusted to different angles by rotating the transverse rod, allowing the shading angle to adapt to different solar irradiation angles at different positions and times, while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent enables periodic adjustment of the umbrella angle through the clutch mechanism, which allows the user to rotate the transverse rod to different positions as needed. This periodic adjustment capability ensures optimal shading effect at different times of the day when solar angles change, without requiring a continuously complex adjustment system.
4Ease of operation
If the umbrella is always supported at a same angle, then the structure is simple, but labor-saving to fold/unfold and easy to fix cannot be achieved simultaneously with rotation capability
Solution Approach 1:
The patent removes the rope component that complicated the folding operation. By using a direct mechanical linkage between the sliding block and transverse rod without ropes, the umbrella becomes easier to fold while simultaneously enabling rotation capability through the clutch mechanism that allows the transverse rod to rotate relative to the sliding block.
Solution Approach 2:
The patent implements a dynamic system where the clutch mechanism enables both easy folding through sliding block movement and rotation capability through transverse rod rotation. The mechanical linkage dynamically adapts to allow both folding and rotating operations, achieving both ease of operation and adaptability simultaneously.
