Toy Glider Rear Air Intake Duct Cover Structural Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Toy return gliders suffer from structural weakness and instability, particularly in the coupling of the rear air intake duct cover and the tail section, which affects their performance and lifespan.
Innovation Solution
The design enhances structural strength and stability by incorporating a rear air intake duct cover formed by folding, with symmetrically disposed notches and slots that provide lateral confinement and improved coupling with the tail section, along with adjustable fold lines for enhanced aerodynamics and flight control.

Engineering Contradiction Analysis
1Device complexity
If the rear air intake duct cover is coupled with the body using a simple structure, then the device complexity is reduced, but the structural strength and stability deteriorate
Solution Approach 1:
The rear air intake duct cover is divided into multiple sections with distinct functional features: a coupling area with lateral confinement structures, a notched area for engagement, and a folded configuration. This segmentation allows each portion to perform its specific function optimally while maintaining overall structural integrity without excessive complexity.
Solution Approach 2:
The rear air intake duct cover is formed by folding the body sheet backward, creating a nested configuration where the duct cover integrates within the body structure. The folded portion nests against the body, and the coupling area integrates with the tail section, achieving compact integration that enhances structural strength without adding external complexity.
2Strength
If the coupling area of the rudder with the tail section is made more rigid, then the structural strength is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The coupling area of the rudder is pre-formed with engagement features during the folding process. The rudder is folded upward and backward at a predetermined angle, and the coupling area is configured with lateral confinement structures that engage with the tail section. This preliminary configuration ensures rigid coupling is achieved through the folding action itself, eliminating the need for additional manufacturing steps.
Solution Approach 2:
The rudder coupling area utilizes a dynamic folding mechanism where the rudder is folded upward and backward at a specific angle to engage with the tail section. The lateral confinement structures are formed through this dynamic folding action, creating a rigid coupling that is inherently integrated into the manufacturing process rather than requiring separate assembly steps.

AI summary
An toy return glider having a first sheet member with a head cover section, a wing section and a tail section disposed along a longitudinal axis, and a rear air intake duct disposed within a connecting area between the wing section and the tail section. The toy glider also has a second sheet member with a body and rudders disposed along the longitudinal axis. The body has two longitudinal fold lines parallel to the longitudinal axis, and when the second sheet member is folded upward, two first slots extend obliquely rearward and downward with the rear air intake duct cover coupled with the two first slots, and the head cover section bonds a front section of the body to form a front air intake duct. The toy glider enhances the structural strength, overall stability and life time of the glider.
