Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing box frames for LED displays are weak and prone to deformation, especially when used as floor tile screens, posing safety risks.
Innovation Solution
A reinforced box frame design featuring alternating connecting seats and frames, with inner and outer plates separated by a partition and reinforced with staggered reinforcing structures, enhancing structural integrity and stress distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple load-bearing structures are used to make the box frame, then the frame strength is improved, but the overall structure becomes heavier and more complex
Solution Approach 1:
The box frame is divided into multiple frames that are connected through connecting seats, forming a modular structure. Each frame can be independently manufactured and assembled, reducing overall complexity while maintaining strength through the distributed load-bearing design.
Solution Approach 2:
The frame incorporates both metal components (for structural strength) and plastic components (for connecting seats and sealing elements), creating a composite structure that optimizes the properties of each material to achieve high strength with reduced complexity.
2Weight of moving object
If the box frame structure is simplified to reduce weight, then ease of installation is improved, but the frame strength decreases leading to deformation
Solution Approach 1:
The frame is segmented into multiple lightweight components connected through joining structures, distributing the load across multiple points rather than requiring a single heavy continuous structure, thus reducing overall weight while maintaining strength.
Solution Approach 2:
The connecting seats incorporate three-dimensional joining structures that provide multiple load paths and structural reinforcement without adding significant weight, allowing the frame to achieve high strength-to-weight ratio through spatial configuration rather than material quantity.
3Ease of manufacture
If the box frame uses fewer reinforcing structures, then manufacturing complexity is reduced, but the bearing capacity and toughness decrease
Solution Approach 1:
The reinforcing structures are divided into discrete, standardized components that can be manufactured using common processes and assembled through simple joining operations, reducing manufacturing complexity while maintaining effective reinforcement.
Solution Approach 2:
Reinforcing structures are strategically placed at specific high-stress locations within the frame rather than uniformly distributed, providing maximum bearing capacity and toughness where needed while minimizing overall manufacturing complexity and material usage.
