Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ski binders are made rigid to ensure stability, then reliability is improved, but turning performance and speed are worsened
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid, fixed binding system with a dynamic, movable binding support plate that can tilt and sway relative to the ski. The support plate is connected via rods that allow rotational movement, enabling the binding to adapt dynamically to skiing conditions. This dynamic capability allows the binding to maintain stability when needed while permitting the flexibility required for turning and speed, thus resolving the contradiction between reliability and speed performance.
Solution Approach 2:
The patent implements parameter changes by introducing variable tension springs that can adjust the tension level of the binding support system. By changing the tension parameter, the system can shift between more rigid (higher tension) and more flexible (lower tension) states, allowing optimization for different skiing conditions. This parameter adjustment capability enables the binding to provide stability when required while allowing flexibility for turning and speed when needed, resolving the contradiction between reliability and speed.
2Stability of the object's composition
If conventional ski binders are made rigid to maintain position, then stability is improved, but turning ability is worsened
Solution Approach 1:
The patent applies dynamics by creating a binding system where the support plate can dynamically tilt and sway on rods rather than being rigidly fixed. This dynamic structure maintains positional stability through spring tension while allowing the necessary movement for turning. The system adapts its degree of freedom based on skiing conditions, providing stability when needed and turning flexibility when required, thus resolving the contradiction between position stability and turning ability.
Solution Approach 2:
The patent applies segmentation by dividing the binding system into separate movable components: the support plate, rods, and springs. This segmentation allows each component to perform its specific function - the springs maintain tension, the rods provide rotational freedom, and the plate supports the binding. This modular, segmented structure enables the binding to maintain overall stability while allowing localized movement for turning, resolving the contradiction between position stability and turning ability.
3Reliability
If rigid bindings are used to prevent movement, then reliability is improved, but vibration and fatigue increase
Solution Approach 1:
The patent applies beforehand cushioning by introducing tension springs that act as cushioning elements between the rigid binding components and the ski. These springs absorb and dampen vibrations and shocks before they can be transmitted to the skier, while still maintaining reliable binding function. The spring-based cushioning system protects against harmful vibrations and reduces fatigue, thus resolving the contradiction between reliability and harmful factors like vibration and fatigue.

AI summary
A ski binding system includes a binding support configured to support a toe piece and a heel piece of the ski binding system on a ski, wherein the bindings support includes at least one bindings support plate to which the toe piece and the heel piece are attached, wherein the at least one bindings support plate is maintained in parallel position to the ski under spring tension, and is configured to tilt when subjected to a tilting force to allow the ski bindings to sway, said tilting force being against the spring tension.
