Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail print apparatuses face challenges in accurately printing on fingers of varying lengths due to instability and the need for multiple restraining devices, leading to inefficiencies and increased costs, as well as inconvenience in use by multiple users.
Innovation Solution
A nail print apparatus with a printing finger fixation section that includes a sliding finger insertion member, a nail portion exposure window, a finger pressing section, and an abutment member to securely position and fix the finger, allowing for precise printing without the need for multiple restraining devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single restraining device is used for all users, then device complexity is reduced, but fingers of different lengths cannot be sufficiently fixed
Solution Approach 1:
The finger insertion member is designed to slide along the finger inserting direction, allowing it to dynamically adjust its position according to the length of the printing finger. This dynamic adjustment mechanism enables a single restraining device to accommodate fingers of different lengths while maintaining reliable fixation, resolving the contradiction between device simplicity and fixation accuracy.
Solution Approach 2:
The position of the finger insertion member is changed as a variable parameter to match different finger lengths. By allowing the insertion member to move to different positions along the finger inserting direction, the system adapts to various finger sizes without requiring multiple dedicated restraining devices, thus reducing device complexity while maintaining reliability.
2Reliability
If multiple restraining devices are prepared for different finger sizes, then finger fixation accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The finger insertion member is designed with universal functionality to accommodate all finger sizes through its sliding mechanism. Instead of requiring multiple specialized restraining devices for different finger lengths, a single multi-functional insertion member can adapt to various finger sizes by changing its position, thereby reducing device complexity while maintaining fixation accuracy across all users.
Solution Approach 2:
The dynamic sliding capability of the finger insertion member allows it to adapt its position based on the inserted finger's length. This dynamic adjustment eliminates the need for multiple static restraining devices with fixed positions, reducing device complexity while preserving the ability to accurately fix fingers of different sizes.
3Manufacturing precision
If the printing head is placed close to the nail, then fine printing is enabled, but the nail and finger may be smeared or the printing head may break
Solution Approach 1:
The finger insertion member acts as an intermediary structure between the printing head and the finger. It provides a stable platform that positions the nail at the optimal distance from the printing head, enabling fine printing while preventing direct contact that would cause smearing or damage. The insertion member mediates the spatial relationship, allowing close proximity for quality printing without harmful effects.
Solution Approach 2:
The finger insertion member performs preliminary positioning of the finger before printing occurs. By pre-positioning the nail at the correct distance and angle relative to the printing head, the system ensures that printing can proceed at close proximity for high precision without risking smearing or head breakage, as the geometric relationship is established in advance.
4Ease of operation
If the printing finger is not fixed, then ease of operation is improved, but printing accuracy deteriorates due to finger movement
Solution Approach 1:
The finger insertion member is designed to be self-adjusting through its sliding mechanism. When a finger is inserted, the member automatically moves to the appropriate position based on the finger's length, eliminating the need for manual adjustment or complex fixation procedures. This self-service capability maintains ease of operation while achieving precise positioning for accurate printing.
Solution Approach 2:
The dynamic sliding feature of the finger insertion member allows it to automatically adapt to different finger lengths without requiring complex manual adjustment. Users simply insert their finger, and the member dynamically positions itself to provide accurate fixation, maintaining ease of operation while ensuring printing accuracy through automatic adaptation rather than complex user manipulation.
