Display Module Bottom Sash Reinforcement via Bead Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules face challenges in achieving sufficient strength while maintaining a slim profile, as they tend to compromise on thickness to reduce size.
Innovation Solution
A display module design incorporating a reinforcing panel attached to a bottom chassis using double-sided tape, with elongated ridge portions and a same-material construction, enhances strength by distributing stress and preventing bending, allowing for a slim profile without compromising structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the bottom sash is made thinner to achieve a slim profile, then the thickness is reduced, but the strength and structural integrity deteriorate
Solution Approach 1:
The patent introduces bead parts that extend in the thickness direction (third dimension) to provide structural reinforcement. By creating protrusions and recesses along the thickness axis, the bottom sash gains enhanced strength without increasing its overall planar dimensions, thus resolving the contradiction between slim profile and structural integrity
Solution Approach 2:
The patent combines the bottom sash made of first material with reinforcing panels made of second material (different thermal expansion coefficient). This composite structure provides both mechanical strength and thermal management capabilities, allowing the sash to maintain strength while remaining thin, and also addressing thermal expansion issues
2Strength
If reinforcing panels are added to enhance strength, then the structural support is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the reinforcing panels: they provide mechanical strength reinforcement, thermal expansion compensation (when made of different material), and structural support for mounting components. By combining these functions into a single component, the design avoids adding separate elements for each function, thus reducing overall device complexity while maintaining enhanced strength
Solution Approach 2:
The reinforcing panels serve multiple purposes simultaneously: structural reinforcement, thermal management interface, and component mounting substrate. This multi-functionality reduces the need for additional separate components, thereby enhancing strength without proportionally increasing device complexity
