Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional polyurethane foam and polyester resin are used for surfboard construction, then ease of manufacture and initial performance are achieved, but environmental toxicity and performance degradation over time occur
Solution Approach 1:
The patent changes the material parameters from conventional polyurethane foam and polyester resin to alternative materials such as bio-based foams, epoxy resins, and natural fibers. This substitution maintains the structural functionality while eliminating toxic substances, thereby resolving the contradiction between reliability and environmental harm.
Solution Approach 2:
The invention employs composite material structures combining multiple layers of foam cores, resin systems, and fiber reinforcements. This composite approach allows optimization of both mechanical performance durability and environmental compatibility by selecting non-toxic materials that work synergistically.
2Ease of manufacture
If conventional foam blocks are used for surfboard construction, then ease of shaping is achieved, but material waste and environmental impact increase
Solution Approach 1:
The patent uses pre-formed foam blocks with optimized density distributions and pre-cut shapes that reduce the need for extensive material removal during shaping. This preliminary preparation maintains ease of manufacture while minimizing waste generation.
Solution Approach 2:
The invention implements material recovery processes where off-cuts and waste materials from shaping operations are collected, recycled, or repurposed. This approach reduces overall material waste while maintaining the ease of manual shaping process.
3Adaptability or versatility
If multiple middlemen are involved in the surfboard value chain, then distribution reach is improved, but carbon footprint and cost increase
Solution Approach 1:
The patent segments the value chain into modular components: local shaping workshops produce boards, regional distribution hubs consolidate shipments, and direct-to-consumer digital platforms handle sales. This segmentation reduces the number of intermediate handlers and optimizes each segment's efficiency, lowering overall carbon footprint while maintaining distribution reach.
Solution Approach 2:
The invention introduces a digital platform as a virtual intermediary that connects manufacturers directly with consumers, eliminating the need for physical intermediaries. This digital mediator maintains market reach while significantly reducing the carbon footprint associated with traditional multi-layer distribution networks.

AI summary
A process for manufacturing a rigid aquatic floating object including an elongate three-dimensional external profile having in total a main length extending from its nose to its tail, a thickness, a width, a deck and an underside. The process includes a) digitally modelling the floating object to be manufactured, b) producing a hollow and apertured internal skeleton by additive manufacturing/3D printing of a multitude of plastic wires that are locally connected to one another geometrically and that reproduce a three-dimensional mesh obtained in a), c) placing the result under vacuum and bonding at least one composite sheet made of fibre and resin around the skeleton forming a shell, d) applying successive fibre-and-resin layers so as to reinforce, via stratification, the shell of step c), and e) finishing the external surface of the stratified sheets made of fibre-and-resin composite by sanding to obtain the final shape of the floating object.
