Solution Overview
Problem
Existing construction panels lack sufficient strength and durability while being lightweight, and their assembly often results in uneven surfaces and potential trip hazards at joints, especially under heavy loads such as vehicles or aircraft.
Innovation Solution
A panel design featuring paired walls defining channels with integrated strengthening members and a fluid-tight connection using a tubular element and plastic rivet, which enhances structural integrity and provides a smooth, level surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If panels are made lightweight to reduce transportation costs and handling risks, then ease of operation and transportation cost are improved, but strength and durability deteriorate
Solution Approach 1:
The panel combines multiple materials with complementary properties: a polymeric base material for lightweight characteristics, reinforced with metal or composite strengthening members embedded in channels, and sealed with heat-welded tubular elements. This composite structure achieves high strength-to-weight ratio by integrating materials of different strengths and functions.
Solution Approach 2:
The panel is divided into functional zones: the base polymeric structure provides lightweight support, while discrete strengthening members are positioned in specific channels to reinforce high-stress areas. This segmentation allows optimization of each component for its specific function while maintaining overall lightweight design.
2Area of stationary object
If panels are assembled with joints to cover surfaces, then area coverage is improved, but uneven surfaces and trip hazards are created at joints
Solution Approach 1:
The panel design ensures that adjacent panels connect at the same elevation level through precisely engineered joining edges and recesses. The strengthening members and tubular elements are positioned to maintain a flush surface, creating an equipotential surface that eliminates trip hazards while allowing extensive area coverage through modular assembly.
3Strength
If strengthening members are added to panels to improve strength, then panel strength is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The strengthening members are integrated directly into the panel structure during manufacturing, combining the base panel and reinforcement elements into a single unified component. The tubular sealing elements are heat-welded directly to the panel body, merging multiple functions (structural support, sealing, reinforcement) into integrated assemblies that reduce overall device complexity.
Solution Approach 2:
Strengthening members are pre-positioned in channels within the panel structure during manufacturing, and tubular elements are pre-attached to specific locations. This preliminary integration during fabrication simplifies the final assembly process and reduces the complexity of handling multiple separate components during installation.
4Productivity
If panels are designed for easy assembly to improve construction speed, then productivity is improved, but structural integrity and fluid-tight sealing deteriorate
Solution Approach 1:
Traditional mechanical fastening systems (screws, bolts, clips) are replaced with heat-welded tubular elements that fuse the panel sections together. This thermal joining method creates a permanent, fluid-tight seal while maintaining relatively simple assembly procedures, achieving both ease of construction and reliable sealing.
Solution Approach 2:
The heat-welding process utilizes phase transitions of the polymeric material (melting and solidification) to create permanent bonds between panel sections and tubular elements. This phase change mechanism provides strong, leak-proof joints that are as reliable as permanent structural connections while maintaining straightforward assembly procedures.
