Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable work lights are either too bulky for easy carriage and storage or too small with limited illumination area, requiring frequent movement to cover different areas, and lack adjustability in illumination angle and position, making them inconvenient for tasks like vehicle maintenance.
Innovation Solution
A work light design featuring modular light units that can be assembled and connected in series, with a rotatable connection unit for adjustable illumination range, a lock unit for secure storage, and a power supply unit for efficient electrical configuration, allowing for flexible use and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the size of the work light is increased to increase illumination area, then the illumination area is improved, but the mobility and ease of carriage are worsened
Solution Approach 1:
The work light is divided into multiple detachable light units that can be connected in series. Each light unit can be independently carried or combined with others to provide the required illumination area, allowing users to segment the total illumination need into manageable portable units.
Solution Approach 2:
The light units are designed to be nestable within each other when not in use, with smaller units fitting inside larger ones. This nesting capability dramatically reduces the storage and carrying volume while maintaining the ability to expand illumination area by connecting multiple units when needed.
2Ease of operation
If the work light is made portable with smaller size, then the ease of carriage is improved, but the illumination area is worsened
Solution Approach 1:
The total illumination area is segmented into multiple discrete light units that can be carried separately or combined. This allows users to carry only the number of units needed for the specific task, optimizing the balance between portability and illumination area.
Solution Approach 2:
Each light unit is designed as a universal module that can function independently or be combined with other identical units. The standardized connection interface allows any number of units to be assembled, providing universal applicability across different illumination requirements while maintaining individual unit portability.
3Area of stationary object
If the work light is designed as a fixed installation, then the illumination area is improved, but the adaptability to different positions is worsened
Solution Approach 1:
The work light system transitions from a fixed installation to a dynamic, reconfigurable structure. The detachable connection units allow the light assembly to be dynamically adjusted in length, configuration, and positioning to adapt to different work environments and illumination requirements.
Solution Approach 2:
The fixed structure is segmented into modular units with standardized connection interfaces. This segmentation enables the light system to be assembled and disassembled in various configurations, providing adaptability to different positions and orientations while maintaining the ability to provide large illumination areas when fully assembled.
4Adaptability or versatility
If the work light structure is made complex to provide adjustability, then the adaptability is improved, but the device complexity is worsened
Solution Approach 1:
The complex adjustability requirements are segmented into simple, standardized connection interfaces between modular units. Each connection point provides the necessary adjustment capability through a simple detachable mechanism, avoiding the need for a single complex adjustment system.
Solution Approach 2:
Multiple adjustment functions (length adjustment, positioning, orientation) are merged into the standardized connection interface between light units. This single interface simultaneously provides all adjustment capabilities, reducing overall system complexity while maintaining full adaptability.

AI summary
A work light includes at least one power supply unit, and at least one light unit, and at least one connection unit. The power supply unit, the light unit and the connection unit are electrically connected with each other. The light unit is detachably and pivotally coupled to the connection unit. When two or more of the light units are provided, the light units are coupled with each other in series via the connection unit. By changing the number of the light units, an overall length of the work light is selectively adjusted to adjust an illumination range of the work light according to different illumination applications.
