Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable umbrellas lack structural support to withstand strong winds or precipitation and do not easily collapse into a storage position, limiting their usability and convenience.
Innovation Solution
A collapsible umbrella design featuring a base frame with telescoping members, an upper frame, a water-resistant cover member, and a support skeleton with tension cables, allowing it to be securely worn by a user while providing enhanced strength and easy storage by collapsing into a compact position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional wearable umbrellas use simple cover members without robust structural support, then the device can be worn comfortably and collapsed for storage, but the cover members lack the structural support to withstand strong winds or precipitation
Solution Approach 1:
The frame is divided into multiple telescoping members (first and second telescoping members) with separate functions: one providing structural support and the other enabling collapse. This segmentation allows the device to achieve both strength and storability without requiring a completely complex frame structure.
Solution Approach 2:
The telescoping members utilize a nested structure where one member slides within another, allowing the frame to compress into a compact configuration for storage while maintaining full extension strength during use. This nesting mechanism enables the paradox of being both strong and easily storable.
2Ease of operation
If conventional wearable umbrellas are designed to be collapsible for storage, then they can be easily stowed when not in use, but they do not easily collapse into a storage position and lack ease of operation
Solution Approach 1:
The umbrella employs dynamic telescoping members that can transition between extended and retracted states. The first telescoping member remains extended to maintain structural stability, while the second telescoping member can be dynamically collapsed for storage, providing both reliability and ease of operation.
Solution Approach 2:
By separating the telescoping function into two distinct members with different operational characteristics, the design allows one member to prioritize structural integrity while the other prioritizes collapsibility, resolving the contradiction between stability and ease of storage.
3Volume of moving object
If conventional wearable umbrellas use fixed-length support members, then the structure maintains consistent strength, but the device cannot be collapsed into a compact storage position
Solution Approach 1:
The telescoping members utilize a nested configuration where inner members slide within outer members, enabling the frame to compress into a compact volume for storage while maintaining the ability to extend to full structural strength when needed.
Solution Approach 2:
The support structure is segmented into multiple telescoping sections that can independently adjust their length. This segmentation allows the frame to achieve both compact storage volume and adequate structural strength by extending the necessary members during use.
4Ease of operation
If conventional wearable umbrellas use detachable connections between frame members, then the device can be collapsed and stored easily, but the connections may compromise structural strength under strong winds or precipitation
Solution Approach 1:
The detachable connections are designed to be dynamically configurable - easily engaged and disengaged for collapse operations, yet providing robust structural connectivity when engaged. The connection mechanism transitions between a secure locked state for strength and a released state for collapse.
Solution Approach 2:
The frame uses segmented telescoping members with detachable connections at strategic locations. This segmentation allows the connections to be positioned where they provide maximum structural benefit while enabling collapse functionality, balancing connection strength with ease of operation.
