Kite-Shaped Decorative Lamp With Pulling-String Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kite-shaped decorative lamps tend to tilt or shake excessively when hung due to wind action, compromising their stability and display effectiveness.
Innovation Solution
The kite-shaped decorative lamp incorporates a foldable skeleton and a pulling light string, which together with a hanging assembly, maintain a stable hovering posture by applying upward and downward forces, enhancing structural integrity and reducing tilting and shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional kite-shaped decorative lamp is hung by a single hanging rope, then the lamp can be easily suspended, but the lamp body is prone to tilting or shaking under wind action
Solution Approach 1:
The hanging assembly is divided into multiple components: an upper hanging rope connected to the top of the decorative body, and a lower hanging rope connected to the bottom of the decorative body. This segmentation of the suspension system allows both ropes to work together, distributing the stabilizing force and preventing the lamp from tilting or shaking under wind action while maintaining ease of suspension.
2Device complexity
If a single hanging rope is used to suspend the decorative body, then the structure is simple, but the decorative body cannot maintain a stable hovering posture
Solution Approach 1:
The hanging assembly incorporates dynamic elements including a rotating connector that allows the lower hanging rope to rotate relative to the decorative body, and an adjusting piece that can slide along the lower hanging rope to change the suspension point. These dynamic features enable the lamp to adapt to wind forces while maintaining stability, achieving a stable hovering posture without significantly increasing structural complexity.
3Strength
If the decorative body is made rigid to maintain shape, then the structural strength is improved, but the ability to fold and store is reduced
Solution Approach 1:
The decorative body incorporates a foldable skeleton divided into multiple segments connected by rotating connectors. These segmented structural elements can be rotated relative to each other, allowing the decorative body to maintain its rigid kite shape during operation while enabling compact folding for storage and transport.
Solution Approach 2:
The decorative body uses dynamic rotating connectors at key joints of the skeleton, allowing the structure to transition between its operational rigid state and its storage folded state. This dynamic mechanism maintains structural strength when deployed while providing adaptability for compact storage.

AI summary
A kite-shaped decorative lamp includes a decorative body, a hanging assembly, and a pulling light string. The hanging assembly is connected to an upper surface of the decorative body and configured to hang the decorative body. An upper end of the pulling light string is connected to a lower surface of the decorative body, and a lower end of the pulling light string extends downward. The hanging assembly and the pulling lamp string jointly act on the decorative body to maintain a hovering posture of the decorative body.
