Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light-emitting devices have limitations in reducing size while maintaining functionality and convenience, as existing base member structures do not efficiently optimize the arrangement of light-emitting elements and wiring patterns for compact design.
Innovation Solution
The proposed light-emitting device features a base member with a lower portion and lateral portion, including step portions with specific wiring patterns, allowing for the efficient arrangement and connection of light-emitting elements, which reduces the device's size by optimizing the layout and material distribution.

Engineering Contradiction Analysis
1Volume of moving object
If a conventional base member structure is used, then the device structure is simple, but the device size cannot be reduced effectively
Solution Approach 1:
The base member is divided into multiple step portions (first, second, and third step portions) with different heights and wiring patterns. This segmentation allows different functional areas to be optimized independently, enabling compact arrangement of light-emitting elements and wirings while maintaining electrical connection reliability.
Solution Approach 2:
The invention utilizes vertical dimension by creating step portions at different heights. This multi-level structure allows wiring patterns to be arranged on different planes, reducing the horizontal footprint of the device while providing sufficient space for electrical connections and heat dissipation.
2Volume of moving object
If the base member structure is optimized for compactness, then device size is reduced, but wiring connection complexity increases
Solution Approach 1:
Different step portions are equipped with different wiring patterns according to their specific functional requirements. The first step portion has a first wiring pattern, the second step portion has a second wiring pattern, and the third step portion has a third wiring pattern. This localized optimization simplifies the wiring arrangement in each area while achieving overall compactness.
3Volume of moving object
If light-emitting elements are arranged compactly, then device size is reduced, but heat dissipation becomes more difficult
Solution Approach 1:
The base member is segmented into multiple step portions that can serve different thermal management functions. The stepped structure creates natural heat dissipation pathways through the vertical levels, allowing heat to be conducted away from the light-emitting elements through multiple routes while maintaining compact horizontal dimensions.

AI summary
A base member includes a lower portion and a lateral portion. The lateral portion includes a first lateral surface, a second lateral surface not adjacent to the first lateral surface, and a third lateral surface adjacent to the first lateral surface, and first to third step portions. The first step portion is arranged inward of the first lateral surface along a portion or an entirety of the first lateral surface, and has a first upper surface provided with a wiring pattern. The second step portion is arranged inward of the second lateral surface along a portion or an entirety of the second lateral surface, and has a second upper surface provided with a wiring pattern. The third step portion is arranged inward of the third lateral surface along only a portion of the third lateral surface, and has a third upper surface provided with a wiring pattern.
