Innovation Solution
A modular frame design with adjustable vertical and horizontal lengths, allowing for variable securing positions and interchangeable components, reducing the need for new molds and minimizing steel usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame is integrally molded with fixed mount locations, then the structural strength and stability are improved, but the adaptability to different display module sizes and PCB types deteriorates
Solution Approach 1:
The frame is divided into multiple detachable sections rather than being integrally molded. This segmentation allows different frame sections to be reconfigured and combined to accommodate various display module sizes and PCB types while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
The frame components are designed with universal features that enable a single set of frame sections to serve multiple functions across different display device configurations. The standardized connection interfaces and adjustable mounting locations allow the same frame components to adapt to various display module sizes and PCB types.
2Manufacturing precision
If the frame is integrally molded for each specific configuration, then the manufacturing precision and structural stability are improved, but the production time and cost increase due to separate molds for different sizes
Solution Approach 1:
By segmenting the frame into standardized sections, a single mold can produce multiple frame components that can be assembled in different configurations. This eliminates the need for separate molds for each display module size, reducing production time and tooling costs while maintaining manufacturing precision through consistent molded components.
Solution Approach 2:
The frame sections are pre-manufactured with standardized connection interfaces and mounting features using a single mold. This preliminary action allows rapid assembly for different configurations without requiring new molds, thereby improving productivity while maintaining the manufacturing precision achieved during the initial molding process.
3Strength
If the entire frame is made of steel plate, then the structural strength and durability are improved, but the product weight and manufacturing cost increase
Solution Approach 1:
Instead of making the entire frame from steel plate, different sections of the frame use different materials appropriate to their functional requirements. Critical load-bearing connection points use steel for strength, while non-critical sections use lighter materials, thereby reducing overall weight while maintaining necessary structural strength and durability.
Solution Approach 2:
The frame employs composite construction combining steel components for critical structural elements with lighter materials for other sections. This composite approach achieves the required structural strength and durability through strategic material placement while significantly reducing the overall product weight and manufacturing cost.
4Stability of the object's composition
If the frame is integrally molded with fixed mount locations, then the structural stability is improved, but the logistics cost and storage space increase due to larger volume
Solution Approach 1:
The segmented frame design allows components to be nested or stacked during storage, reducing the overall volume required for logistics and warehousing. The standardized connection interfaces ensure that structural stability is maintained during assembly from these compacted storage configurations.
Solution Approach 2:
The frame sections are designed to nest within each other when not in use, similar to nested dolls. This nesting capability significantly reduces the storage volume and logistics space required while maintaining the structural stability of the assembled frame through standardized connection mechanisms.
