Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If solid wood is used for the post, then the structural strength is sufficient, but the material consumption is high and environmental protection cannot be realized
Solution Approach 1:
The solid wood post is segmented into multiple thin post walls (at least two) that are folded to form a hollow post body. This segmentation allows the use of thinner materials while maintaining structural integrity through the hollow box-like structure, significantly reducing wood consumption and enabling environmental protection.
Solution Approach 2:
The invention uses fiber plate material folded into a hollow structure instead of solid wood. This composite approach creates a post body that achieves comparable or superior strength-to-weight ratio while consuming far less material, resolving the contradiction between strength and material consumption.
2Productivity
If solid wood post is used, then the structural integrity is maintained, but mechanized volume production is difficult due to material properties and process conditions
Solution Approach 1:
The post is divided into flat post walls that can be easily cut, folded, and assembled using standardized mechanical processes. This segmentation enables the post to be manufactured through hole punching and folding operations that are suitable for mechanized volume production, unlike solid wood which requires more complex carving and joining processes.
Solution Approach 2:
The invention changes the manufacturing parameters from solid wood carving to fiber plate punching and folding. This parameter change enables the use of automated punching machines and folding devices, significantly improving productivity and ease of manufacture for volume production.
3Ease of operation
If solid wood post is used, then the connection strength is sufficient, but transmission and mounting are restricted
Solution Approach 1:
The hollow post body structure provides internal space that facilitates the installation of connectors, bolts, and mounting hardware. The segmented wall structure allows for easy drilling and fastening operations, improving transmission and mounting convenience while maintaining connection strength through the hollow structural integrity.
4Quantity of substance
If hollow post body with thin post walls is used, then material consumption is reduced and cost is lowered, but the structural strength may be compromised
Solution Approach 1:
The post body is segmented into multiple thin walls forming a hollow box structure. This segmentation creates a structure that uses minimal material while maintaining high structural strength through the geometric configuration of the hollow body, resolving the contradiction between material quantity and strength.
Solution Approach 2:
The invention uses fiber plate material in a hollow configuration that achieves optimal strength-to-material-ratio. This composite approach allows thin walls to provide sufficient strength while dramatically reducing material consumption and manufacturing cost.

AI summary
A post for a combined light fitting includes a hollow post body composed of at least two post walls, a connector is installed in at least one end of the post body, the connector is provided with a screw connecting hole for connection with outside. All the post walls constituting the post are made of one piece of fiber plate, and on the surface of the fiber plate, at least one V-shaped groove extending along the direction of its height is formed, the V-shaped groove divides the fiber plate into several post walls, and the respective post wall is turned over inward along the V-shaped groove to form the hollow post. In addition, on the upper side and lower side of the fiber plate, positioning grooves are set along the direction of its width, the positioning grooves are perpendicular to the V-shaped groove, a connector is embedded in each of the two ends of the hollow post composed of various post walls after tuned over, and the base of the connector is embedded in the positioning groove for defining the position of the connector.
