Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing model assembly methods using block structures for arc splicing result in difficulty in intuitively seeing the style outline of structures, and the assembled models lack flexibility due to immovable joints.
Innovation Solution
A rapidly pre-assembled model product is formed by sleeving and assembling a trunk model, a head model, arm models, leg models, and a model hand, utilizing ball-head connecting mechanisms and round rod connecting mechanisms to allow rotational adjustments and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If block structure is divided into small pieces for arc splicing, then the model can be assembled from small components, but the style outline of structures cannot be intuitively seen and the assembly becomes very difficult to operate
Solution Approach 1:
The model is divided into modular components (head, trunk, arms, legs, hands) that can be assembled separately and then connected. This segmentation allows for easier manufacturing of individual parts while maintaining overall assembly simplicity through standardized connection interfaces.
Solution Approach 2:
The四肢 components (arms and legs) are designed to be nested within or connected to the trunk model through receiving structures. This nesting approach allows components to be stored within the main body when not in use, simplifying the overall assembly footprint while maintaining ease of operation.
2Stability of the object's composition
If insert pieces connection structure is used, then the model can be assembled, but the joints cannot move and the model is not flexible enough to play and operate
Solution Approach 1:
The connection structures between components are designed with movable joints that allow rotation and adjustment. The receiving structures and connecting pieces incorporate rotational freedom while maintaining stable connections, enabling the model to achieve various poses and configurations for enhanced playability.
Solution Approach 2:
The joint connections allow for parameter changes in terms of angular position and orientation. The ball-head connecting mechanisms and round rod connections enable rotational movement, allowing the model to adapt to different configurations while maintaining structural stability through controlled parameter variations.
