Thin Solar Module Integrated into Notebook Back Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar charging modules integrated with liquid crystal display notebooks increase thickness and weight, compromising structure stability and reliability, and raise manufacturing costs and market competitiveness.
Innovation Solution
A thin-type solar module with a thickness of 4 mm or less is integrated into the notebook, using the same back plate as the display module without additional components, with a concave supporting structure to secure the solar module, allowing it to convert optical energy into electrical energy without altering the original display assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a conventional solar charging module is integrated with the LCD monitor of the notebook, then the notebook can be charged under light environment to increase using time, but the thickness and weight will exceed the specification originally designed for the cover of the notebook
Solution Approach 1:
The patent applies thin-film solar cells with a thickness of 4mm or less, replacing conventional thick solar modules. This thin-film technology allows the solar charging module to be integrated into the notebook cover without exceeding the original thickness specifications, while still providing sufficient light conversion capability to charge the notebook and extend usage time.
2Ease of manufacture
If the solar charging module is directly assembled on the cover of the notebook, then the integration is simplified, but the structure stability and strength will become poor and reliability will be lowered
Solution Approach 1:
The patent merges the solar charging module with the display module by integrating both onto the same back plate. This unified structure allows the display module to provide structural support to the solar module, enhancing overall stability and reliability while simplifying the manufacturing process through combined assembly.
Solution Approach 2:
The patent utilizes the vertical space within the notebook cover structure by creating a concave portion in the back plate. This dimensional adjustment allows the solar module to be positioned in the concave area, providing structural support from the display module while maintaining a flat external surface, thus improving stability without compromising ease of manufacture.
3Ease of manufacture
If the solar charging module is directly assembled on the cover of the notebook, then the assembly is simplified, but the manufacturing cost will be increased and market competitiveness will be reduced
Solution Approach 1:
The patent makes the back plate serve multiple functions: it supports both the display module and the solar charging module, and provides structural reinforcement for the thin solar cells. This multi-functional design eliminates the need for additional separate support structures, reducing component count and manufacturing cost while maintaining ease of assembly.
