Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require large packaging boxes due to the size of their stands, which complicates transportation and storage, and have challenges with assembly stability and productivity.
Innovation Solution
A display apparatus with a stand comprising a first and second stand member connected via an obliquely formed coupling protrusion and groove, allowing diagonal coupling and improved dimensional stability, and a coupling plate for secure attachment of the display unit, reducing packaging size and enhancing assembly performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stand is designed with sufficient width in the front-rear direction to prevent the display unit from falling, then the stability of the display apparatus is improved, but the volume of the packaging box increases
Solution Approach 1:
The stand is divided into a first stand member and a second stand member that can be coupled together. The first stand member includes a coupling protrusion that fits into a coupling groove of the second stand member, allowing the stand to be segmented for compact packaging while maintaining stability when assembled
Solution Approach 2:
The first stand member is inserted into the second stand member through the coupling protrusion and coupling groove mechanism, creating a nested structure that reduces the overall volume when packaged while maintaining the necessary width for stability when assembled
2Reliability
If the stand width is increased to ensure stability, then the reliability of the display apparatus is improved, but the ease of manufacture deteriorates due to increased material usage and complexity
Solution Approach 1:
The stand is segmented into two members that can be manufactured separately using standard extrusion processes, making it easier to manufacture while maintaining reliability through the coupling mechanism that ensures stable assembly
Solution Approach 2:
The coupling protrusion is obliquely formed in a downward direction, changing the geometric parameters of the coupling interface to enable diagonal coupling. This parameter change facilitates easier assembly while maintaining the structural integrity and reliability of the stand
3Volume of stationary object
If the stand structure is simplified to reduce packaging size, then the volume of the packaging box is reduced, but the assembly stability deteriorates
Solution Approach 1:
The stand is segmented into two members that couple together through a protrusion-groove mechanism, allowing compact packaging while maintaining assembly stability through the interlocking coupling structure
Solution Approach 2:
The coupling protrusion is obliquely formed in a downward direction, creating an asymmetric coupling interface. This asymmetric design provides directional guidance during assembly and ensures stable coupling when the first stand member is inserted diagonally into the second stand member
