Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of constructing museum showcases that require high security, insulation, and structural solidity, particularly in supporting heavy transparent walls, makes existing designs difficult to manufacture and assemble efficiently.
Innovation Solution
A museum showcase design featuring a bearing frame with joints connected to horizontal beams, where the weight of the walls is supported by these joints, allowing for simpler and quicker construction by standardizing joint sizes and using adjustable tie rods for horizontal beams of varying lengths, and incorporating corner and intermediate joints for added stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional welded beam structures are used to support heavy transparent walls, then structural solidity is achieved, but manufacturing complexity and assembly difficulty increase significantly
Solution Approach 1:
The bearing frame is segmented into independent modular components: corner units with integrated joints, horizontal beams, and vertical beams. Each corner unit contains pre-assembled joint mechanisms that can independently support wall weights. This segmentation allows each component to be manufactured separately using standard processes, then assembled through simple connection operations, dramatically reducing overall manufacturing complexity while maintaining structural integrity through the modular arrangement.
Solution Approach 2:
Joints serve as intermediary elements that mediate between the horizontal beams and vertical beams, and ultimately support the transparent walls. These joints are designed as standardized components with built-in load-bearing mechanisms, acting as intermediaries that transfer and distribute wall weights to the vertical beams without requiring complex welded connections between horizontal and vertical elements. This intermediary joint design simplifies the connection geometry and manufacturing processes.
2Adaptability or versatility
If customized beam lengths are used for different showcase sizes, then design flexibility is improved, but production time and assembly complexity increase
Solution Approach 1:
The joint design is universal and multi-functional, serving as a standardized connection element that can accommodate horizontal beams of various lengths and showcase configurations. Each corner unit contains joints that can connect to horizontal beams of different lengths without requiring customization. This universality allows the same joint and beam components to be used across multiple showcase sizes and designs, enabling rapid production through standardized manufacturing processes while maintaining design flexibility through configurable arrangements.
3Stability of the object's composition
If heavy transparent walls are supported by horizontal beams, then structural stability is achieved, but stress on beams increases and simplifies construction
Solution Approach 1:
The load support function is segmented and redistributed: instead of horizontal beams directly supporting wall weights, the corner units with integrated joints serve as intermediate support points. The joints are positioned at the corners where vertical beams connect, creating a load path that segments the wall weight into discrete support points at the corners, rather than distributing continuous load along the horizontal beams. This segmentation reduces bending moments and stress in the horizontal beams while maintaining structural stability through the corner support mechanism.
4Reliability
If complex welded structures are used to ensure security and insulation, then protection requirements are met, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The showcase is segmented into modular units (corner units with joints, horizontal beams, vertical beams, transparent walls) that can be independently manufactured and assembled. Each corner unit contains pre-assembled joint mechanisms that provide secure connections without requiring on-site welding. The modular segmentation allows each component to be manufactured with integrated security and insulation features, then assembled through simple mechanical connections, dramatically improving ease of assembly while maintaining protection requirements through the designed joint and component interfaces.
Solution Approach 2:
The connection system transitions from static welded joints to dynamic, reversible mechanical connections. The joints are designed with movable or adjustable connection mechanisms that allow for easy assembly and disassembly while maintaining secure locked positions when assembled. This dynamic connection approach enables the structure to be easily configured, assembled, and disassembled while providing reliable security and insulation when in the assembled state, contrasting with permanent welded connections.

AI summary
This museum showcase comprises a bearing frame and fixed and/or openable walls supported by the bearing frame. The bearing frame comprises a platform that includes joints connected to horizontal beams. The fixed and/or openable walls of the showcase are supported only by the joints. The weight of the walls is supported by the joints, whereas the horizontal beams are not subjected to significant stresses. It is thus possible to design the showcase in a particularly simple and therefore quick manner, choosing the lengths of each beam according to the dimensions of the showcase and leaving the support of the weights to just the joints.
