Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices are inconvenient to maintain due to the need to separate the lamp head from the base for lampshade replacement, lack flexibility in shape and height adjustment, and are limited by a fixed power source, restricting their usability.
Innovation Solution
A modular lighting device with a base and lamp head unit featuring removable connecting modules and a portable power supply, allowing for easy lampshade replacement, adjustable shape and height, and operation anywhere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the lamp head is separated from the base for lampshade replacement, then the lampshade can be replaced, but the replacement process becomes inconvenient and time-consuming
Solution Approach 1:
The lighting device is divided into separate modules: base, lamp head unit, and supporting unit, each with standardized connecting modules. This segmentation allows the lampshade to be replaced by simply detaching the lamp head unit from the base using the connecting modules, without needing to separate internal components or disassemble the entire device.
Solution Approach 2:
The connecting modules are designed with universal compatibility across different components (base, lamp head unit, supporting unit). The standardized interface allows any lamp head unit to connect to any base, and lampshades can be attached to any lamp head unit, creating a universal system that simplifies maintenance and replacement operations.
2Stability of the object's composition
If the base is electrically connected to the lamp head in a fixed manner, then the structure is stable, but the shape and height of the lighting device cannot be changed
Solution Approach 1:
The connecting modules incorporate a removable and reconfigurable design that allows the lighting device to transition between fixed and adjustable states. Users can detach and reattach components to change the device's shape and height, while the modular connection ensures stable electrical and mechanical connections when assembled.
Solution Approach 2:
The device is segmented into independently configurable modules (base, supporting unit, lamp head unit) that can be arranged in different configurations. The standardized connecting modules maintain structural stability while allowing reconfiguration to achieve different shapes and heights based on user needs.
3Reliability
If the lighting device is connected to a specific type of power source, then the electrical connection is reliable, but the applicable range is limited when moved to places without such power sources
Solution Approach 1:
The base incorporates a universal power interface that can accept multiple power source types through the standardized connecting modules. This universal design allows the device to connect to wall outlets, portable power banks, or other power sources, maintaining reliable electrical connection while significantly expanding the range of usable locations.
Solution Approach 2:
The connecting modules serve as an intermediary between the power source and the lamp head unit, providing a standardized interface that can adapt to different power source types. This intermediary layer maintains reliable electrical connection while enabling flexibility in power source selection and location mobility.
4Reliability
If the lamp head structure has a wider distal end, then the lampshade can be securely mounted, but the lamp head must be separated from the base for lampshade replacement
Solution Approach 1:
The lampshade mounting function is separated from the lamp head-base connection function. The lamp head unit maintains its wider distal end for secure lampshade mounting, while the removable connecting module at the base interface allows the entire lamp head unit to be detached and reattached, enabling lampshade replacement without permanent structural changes or complex disassembly.

AI summary
A modular lighting device includes a base and a lamp head unit. The base includes a base body and a first connecting module disposed at a top end of the base body and having a first connecting portion and a first conductive portion. The lamp head unit includes a bottom seat, a lamp body disposed on the bottom seat, and a lamp shell connected to the bottom seat. The bottom seat includes a second connecting module disposed at a bottom end thereof and having a second connecting portion connected removably to the first connecting portion, and a second conductive portion electrically connected to the first conductive portion. The lamp shell has a maximum width disposed at a position adjacent to a bottom end thereof and smaller than or equal to that of the bottom seat.
