Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mannequins with immobile injection-molded parts and limited movable sections struggle to accurately adjust circumference, leading to abrupt contours and distorted visual effects, making it difficult for customers to achieve perfect clothing fits.
Innovation Solution
A mannequin design featuring a support frame with peripherally arranged plates that include driving and driven plates, allowing for adjustable circumference regulation through a mechanism of main and auxiliary regulating bands, sliding hinges, and a circumference transmission mechanism to ensure smooth contour continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only the abdomen or chest and other prominent parts are provided with a movable plate, then the circumference of these parts can be adjusted, but the movable plate will obviously protrude or sink from other parts and thus cannot smoothly join with these other parts to form a smooth curve
Solution Approach 1:
The torso is divided into multiple regulating regions (chest, waist, abdomen, hip, and intermediate regions), with each region equipped with its own movable plate. This segmentation allows independent adjustment of each body section while maintaining overall contour smoothness, as each plate can be positioned to match the natural curvature of its specific region.
Solution Approach 2:
Different regions of the torso are treated with different adjustment characteristics. The regulating regions at prominent parts (chest, waist, abdomen, hip) have movable plates for circumference adjustment, while the intermediate regions have fixed plates to maintain structural stability. This local differentiation ensures that adjustment occurs only where needed while preserving smooth transitions elsewhere.
2Ease of manufacture
If most regions of the body surface are made as immobile injection-molded parts, then the manufacturing is simple and cost-effective, but the mannequin cannot be adjusted to match different customer figures
Solution Approach 1:
The mannequin torso is segmented into regulating regions with movable plates and intermediate regions with fixed plates. This allows only specific portions to be adjustable while the majority remains as simple injection-molded parts, balancing manufacturing ease with adaptability for different customer figures.
Solution Approach 2:
The mannequin transitions from a completely static structure to a dynamically adjustable one by incorporating movable plates in regulating regions. These plates can be repositioned along the support frame to adjust circumference, while the overall structure remains largely fixed, providing adaptability without requiring complete redesign of the entire mannequin.
3Manufacturing precision
If multiple regulating regions are provided with driving plates and driven plates, then the circumference adjustment accuracy is improved, but the device complexity increases
Solution Approach 1:
Adjacent driving plates and driven plates are connected through hinge mechanisms to form integrated regulating mechanisms. This merging reduces the number of independent components and simplifies the overall structure while maintaining the ability to achieve precise circumference adjustments across multiple regulating regions.
Solution Approach 2:
The driven plates act as intermediary elements between the driving plates and the external adjustment mechanism. These driven plates transmit and distribute the adjustment force smoothly across adjacent regulating regions, reducing the complexity of direct connections while improving adjustment accuracy through gradual, coordinated movement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mannequin achieves a high degree of simulation by maintaining contour continuity and simplifying circumference adjustments, enhancing the accuracy of clothing fits and visual realism.
Implementation Method 1
the sliding hinge includes a first hinge support and a second hinge support fixedly connected with the driving plate and the driven plate respectively, and a hinge rotating shaft connecting two of the first hinge support and the second hinge support, wherein the first hinge support or the second hinge support is provided with a sliding groove for the hinge rotating shaft to rotate and slide

AI summary
The present application discloses a mannequin. The mannequin includes: a torso, upper limbs on both sides of the torso and a yawing device used for regulating the lateral swing of the upper limb being arranged at the joint between the upper limb and the torso. An upper limb fixing seat is arranged at the root of the upper limb. The yawing device includes: a yawing bracket hinged with the top of the upper limb fixing seat and a regulating piece with an inner end movable relative to the bottom of the yawing bracket. The outer end of the regulating piece being fixedly connected with the yawing bracket, and the movement of the regulating piece is used to drive the top of the upper limb fixing seat to swing relative to the yawing bracket, such that the upper limb is driven to swing.
