Solution Overview
Problem
Conventional methods struggle to maintain the predetermined shape of a personal care product due to fluid composition flow during solidification, leading to difficulties in achieving high shape and dimensional accuracy.
Innovation Solution
A production method involving a nozzle with a specific diameter range and distance-to-diameter ratio, combined with controlled supply and movement, is used to form deposits on an object with high precision, allowing for accurate shaping and decoration of personal care products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods are used to form personal care products, then production can proceed with standard equipment, but the predetermined shape cannot be maintained due to fluid composition flow during solidification
Solution Approach 1:
The patent applies parameter changes by precisely controlling the nozzle diameter (0.01-2 mm) and the distance-to-diameter ratio (0.35-3) to maintain composition stability during deposition. This controlled parameter approach prevents fluid composition from flowing away during solidification, thereby maintaining the predetermined shape and achieving high manufacturing precision.
Solution Approach 2:
The patent employs preliminary action by pre-establishing the optimal nozzle parameters (diameter and distance-to-diameter ratio) before the deposition process begins. This preliminary configuration ensures that the composition is deposited in a controlled manner that maintains shape stability throughout the solidification process, preventing shape distortion.
2Manufacturing precision
If a nozzle with specific diameter range and distance-to-diameter ratio is used, then high shape and dimensional accuracy can be achieved, but the device configuration becomes more specific and constrained
Solution Approach 1:
The patent defines specific parameter ranges (nozzle diameter: 0.01-2 mm, distance-to-diameter ratio: 0.35-3) that balance manufacturing precision with practical device implementation. By establishing these parameter boundaries, the patent achieves high dimensional accuracy while maintaining reasonable device configurability within the specified ranges.
Solution Approach 2:
The patent applies partial action by specifying a focused range of nozzle parameters rather than requiring extreme precision across all possible values. The distance-to-diameter ratio range of 0.35-3 provides sufficient control for high dimensional accuracy while allowing practical flexibility in device design and operation.

AI summary
A production method for a personal care product applicable to a human body can include a forming step in which a nozzle is moved relative to an object while a composition having fluidity is supplied from the nozzle to the object to form a deposit derived from the composition on the object. A nozzle with a nozzle diameter of 0.01 mm or more and 2 mm or less may be used as the nozzle. In the forming step, the composition can be supplied such that a ratio of a distance between a tip of the nozzle and the object to the nozzle diameter (distance/nozzle diameter) is set to 0.35 or more and less than 3.
