Multi-axis Dressmaker Form with Synchronous Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dressmaker forms require complicated size adjustments and lack auxiliary marks for body length adjustment, making it difficult to accurately measure and design garments that fit well, especially considering the three-dimensional angular characteristics of the human body.
Innovation Solution
A body-size-adjustable dressmaker form with a central-support adjusting system, neck adjusting system, chest adjusting system, waist adjusting system, hip adjusting system, arm adjusting system, and upper-body outer housing, utilizing multi-axis synchronous co-directional adjusting devices and telescopic structural members with scales for precise adjustments, allowing for easy synchronous adjustment of body dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional dressmaker forms are used with manual size adjustment, then the form can be adjusted to different sizes, but the adjustment operation becomes very complicated and time-consuming
Solution Approach 1:
The patent combines multiple adjustment mechanisms (chest, waist, hip, arm adjustments) into a single integrated multi-axis synchronous co-directional adjusting device. All adjustment components share common mounting structures, transmission rods, and control knobs, allowing simultaneous adjustment of multiple body dimensions through one unified control interface, thereby simplifying the operation while maintaining comprehensive size adaptability
Solution Approach 2:
The adjusting device is designed with universal mounting positions and common transmission mechanisms that can accommodate multiple adjustment axes. The same bevel gear and telescopic structural member configurations are reused across different adjustment systems, enabling a single device to perform multiple adjustment functions for chest, waist, hip, and arm measurements
2Measurement precision
If conventional dressmaker forms are used, then basic size adjustment is possible, but there is no auxiliary mark for body length adjustment making precise measurement difficult
Solution Approach 1:
The patent incorporates visual auxiliary marks (indicated by different color coding or marking systems on the telescopic structural members and scale indicators) that change or become visible during adjustment to indicate precise measurement positions. These visual cues help operators accurately read and record body dimension measurements without adding complex mechanical measurement devices
Solution Approach 2:
The patent introduces auxiliary marks and scale indicators as intermediary elements between the adjustment mechanisms and the operator. These visual indicators serve as mediators that translate the mechanical adjustment positions into readable measurement values, enabling precise measurement while keeping the overall structure relatively simple
3Adaptability or versatility
If conventional dressmaker forms are used, then basic adjustment is possible, but it is impossible to measure and design a complete garment by arm adjustment
Solution Approach 1:
The patent divides the dressmaker form into separate adjustable segments for different body parts (chest, waist, hip, arm), each with its own adjustment mechanism mounted on the upper-body outer housing. This segmentation allows independent adjustment of arm dimensions while maintaining the ability to adjust other body parts, enabling complete garment design and fitting through systematic arm adjustments

AI summary
A body-size-adjustable dressmaker form includes a central-support adjusting system, a neck adjusting system, a chest adjusting system, a waist adjusting system, a hip adjusting system, an arm adjusting system, a base and an upper-body outer housing. The chest adjusting system, the waist adjusting system and the hip adjusting system each include a multi-axis synchronous co-directional adjusting device and an adjusting knob. The central-support adjusting system includes an upper-body support assembly provided with mounting positions adapted to the multi-axis synchronous co-directional adjusting devices. Each multi-axis synchronous co-directional adjusting device includes a telescopic structural member connected with the adjusting knob. Multiple housing units are sequentially connected to form the upper-body outer housing, and the multiple housing units are connected with the telescopic structural members respectively. When the adjusting knob is rotated, the telescopic structural members drive the housing units to move close to or away from each other.
