Fan-Shaped Tent Skeleton Rotary Rod Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan-shaped tents with complex structures are cumbersome to mount and detach, wasting time and being inconvenient for short-time vehicle stops during travel.
Innovation Solution
A fan-shaped tent skeleton with a laterally arranged base plate and rotary rod assembly that unfolds like a fan, allowing for easy setup and teardown, featuring a fixed seat and external movable shafts for connection of upper and lower rotary rods, and a connecting structure for securing the tent fabric, enabling direct attachment to a roof rack for increased convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex structure is used for the fan-shaped tent, then the support strength and coverage area are improved, but the ease of operation deteriorates
Solution Approach 1:
The tent skeleton is divided into multiple rotary rods (upper and lower rotary rods) that can rotate independently relative to the base plate. Each rotary rod acts as an independent segment that can be unfolded or folded separately, allowing the structure to achieve full expansion for strong support when needed and compact folding for easy storage and transport.
Solution Approach 2:
The tent skeleton employs dynamic rotary joints that allow the rotary rods to rotate between folded and unfolded states. This dynamic mechanism enables the structure to transition smoothly between compact and expanded configurations, providing both strong support when unfolded and ease of operation through simple rotational movement without complex assembly procedures.
2Area of stationary object
If a complex structure is used for the fan-shaped tent, then the coverage area is improved, but the time consumption for mounting and detaching increases
Solution Approach 1:
The rotary rods are pre-positioned and pre-configured on the base plate during manufacturing, with all necessary connections and joints already in place. This preliminary arrangement allows the user to simply unfold the pre-configured structure rather than assembling it from separate components, significantly reducing mounting time while maintaining full coverage area capability.
Solution Approach 2:
The dynamic rotary joint mechanism allows rapid expansion from a compact folded state to a full coverage unfolded state through simple rotational movements. The structure can be deployed and stowed quickly without complex assembly steps, reducing time loss while achieving the desired coverage area when needed.
3Stability of the object's composition
If multiple rotary rods are arranged to optimize support, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
Multiple rotary rods (upper and lower) are merged into a single integrated rotary rod assembly that rotates together as a coordinated unit. This merging approach maintains structural stability through multiple support elements while reducing operational complexity by treating them as a unified assembly rather than separate independent components.
Solution Approach 2:
The rotary rod assembly serves multiple functions simultaneously: it provides structural support, enables fan-shaped expansion for coverage, and allows compact folding for storage. The same rotary joint mechanism handles all these functions, reducing overall device complexity compared to having separate systems for each function.
