Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser-based surface treatment apparatuses for clothing require multiple handling steps, leading to increased treatment times and labor costs, and pose safety risks due to the alignment of the laser generator with the operator's access point.
Innovation Solution
A semiautomatic apparatus with multiple rotating arms and dual laser generators positioned on opposite sides of the treatment chamber, allowing for simultaneous treatment of multiple surfaces of clothing items without operator intervention, thereby reducing handling and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single laser generator is used to treat all surfaces of clothing items, then the device complexity is reduced, but the treatment time increases significantly due to multiple handling steps
Solution Approach 1:
The treatment system is segmented into multiple independent laser generators, each dedicated to treating specific surfaces (front, rear, sides) of clothing items. This segmentation allows parallel processing of different surfaces simultaneously, reducing total treatment time while maintaining manageable device complexity through modular architecture
Solution Approach 2:
Multiple laser generators are merged into a single integrated treatment chamber with coordinated control, allowing simultaneous operation on multiple items. The merging of multiple treatment functions into one system achieves high productivity without proportionally increasing overall system complexity
2Ease of operation
If the laser generator is aligned with the operator's access point for easy loading/unloading, then the ease of operation is improved, but operator safety deteriorates due to laser interference risk
Solution Approach 1:
The laser generators are positioned asymmetrically at opposite sides of the treatment chamber rather than aligned with the operator's access point. This asymmetric arrangement allows the operator to load and unload items from one side while lasers operate from opposite sides, eliminating laser interference with operator safety while maintaining ease of operation
Solution Approach 2:
The treatment chamber structure acts as an intermediary barrier between the laser generators and the operator. The chamber design allows laser beams to treat items without directly exposing the operator to laser radiation during loading/unloading operations, protecting operator safety while maintaining operational efficiency
3Manufacturing precision
If multiple handling steps are used to treat all surfaces of clothing items, then the manufacturing precision of surface treatment is improved, but the loss of time increases due to repeated handling
Solution Approach 1:
The system maintains continuous useful action by having multiple laser generators operate simultaneously on different surfaces of multiple clothing items. Items rotate on arms to present different surfaces to different lasers without stopping the treatment process, eliminating idle time between handling steps while maintaining treatment precision through controlled rotation and positioning
Solution Approach 2:
The clothing items are dynamically rotated on rotating arms during treatment, allowing different surfaces to be presented to different laser generators in sequence. This dynamic positioning enables continuous treatment of all surfaces without stopping the process, reducing handling time while maintaining precision through controlled rotational movement

AI summary
A semiautomatic apparatus for surface treatment of items of clothing using a laser source, in which the items have front, rear and side surfaces, the apparatus includes support means, rotating about substantially vertical axes, movement means for moving the support means and laser means for surface treatment of the items. The laser means include at least one first laser generator and a second laser generator for directing laser beams respectively to the front, the rear and/or the side surfaces of the items to be treated, and the support means include multiple arms configured to move from a loading/unloading station for an item to be treated or being treated to two work stations for the items to be treated. A passage is provided for an operator to access the loading/unloading station, the generators are located at opposite sides of the passage to avoid interference of the laser beams with the operator.
