Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunshades are heavy and difficult to move due to their weight, requiring significant time and effort to adjust or reposition them.
Innovation Solution
A removable sunshade base with a sliding groove and pull rod system, featuring first and second sliding wheels, a clamping slot, and a handle, allowing the sunshade base to be easily moved by pulling the pull rod, which can be inclined for easier handling and adjusted in length for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sunshade base is made heavy to support the sunshade body, then the supporting stability is improved, but the ease of moving the sunshade deteriorates
Solution Approach 1:
The sunshade base is divided into a stationary base body and a movable pull rod assembly. The base body remains heavy for stability, while the pull rod with sliding wheels provides mobility. This segmentation allows the system to simultaneously achieve both stability and ease of movement.
Solution Approach 2:
The sliding wheels act as an intermediary between the heavy base body and the ground. When the pull rod is pulled out, the sliding wheels contact the supporting plane, enabling the heavy base to be moved with minimal effort. This intermediary component resolves the contradiction by decoupling the weight-bearing function from the movement function.
2Stability of the object's composition
If the sunshade base is made heavy to support the sunshade body, then the supporting stability is improved, but the time and effort required to move the sunshade increases
Solution Approach 1:
The sliding wheels are pre-installed on the pull rod, ready for use. When movement is needed, the user simply pulls out the pull rod to engage the sliding wheels, eliminating the need for preliminary preparation or assembly steps. This reduces the time and effort required to move the sunshade.
Solution Approach 2:
The sliding wheels serve as a mechanical intermediary that reduces friction between the heavy base and the ground. By replacing direct contact friction with wheel-based rolling friction, the time and effort required to move the sunshade are significantly reduced while maintaining supporting stability.
3Ease of operation
If the pull rod is made long and adjustable for easier handling, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The pull rod is designed with adjustable length, allowing it to be extended or retracted based on operational needs. This dynamic adjustment capability improves ease of handling by enabling the user to optimize the pull rod length for different situations, while the telescopic mechanism keeps the added complexity manageable.
Solution Approach 2:
The pull rod serves multiple functions: it acts as a handle for pulling, a structural connector, and an adjustable-length lever. This multi-functionality justifies the added complexity by providing versatile operational advantages that simplify various handling tasks.

AI summary
This invention provides a removable sunshade base and a sunshade including the removable sunshade base. The removable sunshade base includes a sunshade base body and a pull rod. A bottom of the sunshade base body has a sliding groove and first sliding wheels. One end of the pull rod has a second sliding wheel, and the pull rod is movably connected with the sliding groove of the sunshade base body such that the pull rod is accommodated in the sliding groove or is pulled out from the sliding groove. When the pull rod is pulled out from the sliding groove, both the first sliding wheels and the second sliding wheel contact one supporting plane to move the sunshade base body.
