Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional picture frames made of wood or metal are expensive to produce and time-consuming to assemble, making them unsuitable for mass production.
Innovation Solution
A picture frame design featuring a picture carrier portion and a frame portion with side and back members hingedly connected, allowing for a cost-effective and simplified assembly process, including an inclined back member configuration that enhances stability and reduces the need for intermediate members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional picture frames are made of wood or metal, then structural strength is improved, but manufacturing cost increases and assembly time increases
Solution Approach 1:
The frame is divided into multiple modular components (side members, back members, picture carrier portion) that can be manufactured separately and assembled together. This segmentation allows for cost-effective production of individual parts while maintaining overall structural strength through the modular assembly.
Solution Approach 2:
Hinge connections serve as intermediary elements that join the frame components together. These hinge connections enable easy assembly and disassembly while maintaining structural integrity, replacing the need for expensive and time-consuming conventional joining methods.
2Stability of the object's composition
If conventional picture frames use traditional assembly methods, then structural stability is improved, but assembly time increases
Solution Approach 1:
The hinge connections provide dynamic assembly capability, allowing the frame components to be easily connected and disconnected. This dynamic joining mechanism maintains structural stability when assembled while dramatically reducing assembly time compared to conventional fixed joining methods.
Solution Approach 2:
The hinge connections are designed to enable self-assembly of the frame components. The interlocking nature of the hinges allows the frame to be assembled without specialized tools or complex procedures, reducing assembly time while maintaining stability.
3Ease of manufacture
If the back member is perpendicular to the picture carrier portion, then assembly simplicity is improved, but structural stability deteriorates
Solution Approach 1:
The back member is intentionally positioned at an asymmetric angle (inclined) rather than perpendicular to the picture carrier portion. This asymmetric configuration creates a more stable triangular structural geometry while still allowing for relatively simple assembly through the hinge connection mechanism.
Solution Approach 2:
The inclined back member introduces an angular dimension to the frame structure, creating a three-dimensional configuration that enhances stability. This dimensional change from a simple perpendicular arrangement to an inclined arrangement improves structural rigidity while the hinge connection maintains assembly simplicity.
