Movable Illumination Device for Multineedle Sewing Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination devices for multineedle sewing machines either obstruct needle threading and replacement due to their fixed position or require troublesome readjustment after maintenance, lacking usability in both scenarios.
Innovation Solution
An illumination device with a support unit that allows the illuminating member to switch between an illuminating position in front of the needle bars and a storage position laterally to the needle bar case, enabling obstruction-free needle access and easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the fluorescent lamp is mounted on the underside of the needle bar case to illuminate the needle base, then the needle base is sufficiently illuminated, but the fluorescent lamp becomes an obstacle in threading the needle thread or replacing needles
Solution Approach 1:
The illumination device is designed to be movable between a first position (illuminating the needle base during sewing) and a second position (retracting to clear the needle threading path). This dynamic repositioning allows the system to optimize both illumination performance and operational accessibility at different times.
Solution Approach 2:
The illumination device is positioned in a direction parallel to the needle bars rather than perpendicular to them, utilizing spatial dimensionality to route the light source around the needle threading path. This dimensional arrangement allows the lamp to illuminate the needle base without directly obstructing the needle eye access path.
2Stability of the object's composition
If the illuminating member is fixedly mounted in the multineedle sewing machine, then the position is stable, but the illuminating member becomes an obstacle in maintenance work
Solution Approach 1:
The illumination device incorporates a movable mounting mechanism that allows it to be repositioned between a forward position (parallel to needle bars) for stable illumination during operation and a rearward position (perpendicular to needle bars) that clears the maintenance area, enabling easy access for servicing.
3Ease of operation
If the illuminating member is made adjustable by a holder with hinges, then the position can be adjusted to avoid obstacles, but the illuminating member needs to be readjusted after maintenance work
Solution Approach 1:
The illumination device is designed with a movable mounting that allows easy repositioning between operational and maintenance positions. After maintenance, the device can be quickly returned to its operational position without complex readjustment procedures, minimizing time loss.
Solution Approach 2:
The illumination device is pre-positioned in a manner that anticipates maintenance needs, allowing maintenance personnel to access the device from the rearward position without requiring complex disassembly or readjustment procedures.

AI summary
An illumination device for a multineedle sewing machine is disclosed. The sewing machine includes a plurality of needle bars having lower ends to which needles are attached respectively and a needle bar case supporting the needle bars so that the needle bars are movable upward and downward. The illumination device includes an illuminating member having a light source, and a support unit located in the needle bar case for supporting the illuminating member so that the illuminating member is switchable between an illuminating position where the illuminating member is located in front of the needle bars or the needles to illuminate a periphery of a needle point of the needle location point of the needle by the light source and a storage position where the illuminating member opens a front side of the needle bar or the needle and is located laterally with respect to the needle bar case.
