Innovation Solution
A roller ski adapter system that includes a two-ski adapter set with front and rear adapters, featuring a wheel braking system with a braking bar held in tension by spring assemblies, and a squeeze plate assembly with cork padding to protect the skis, allowing for secure attachment and braking functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wheel braking system is added to the roller ski adapter, then braking functionality is improved, but device complexity increases
Solution Approach 1:
The braking bar is nested within the lower brake compartment, with the brake line aperture integrated into the compartment structure. The spring assembly is contained within the same compartment, creating a compact nested arrangement that provides braking functionality while minimizing overall system complexity and space requirements.
Solution Approach 2:
The brake line acts as an intermediary element connecting the brake lever assembly to the braking bar. This cable-mediated approach allows for simple transmission of braking force without requiring complex mechanical linkages, reducing overall system complexity while maintaining reliable braking functionality.
2Object-affected harmful factors
If protective padding is added to the squeeze plate assembly, then ski protection is improved, but device complexity increases
Solution Approach 1:
The cork padding is pre-installed on the squeeze plate assembly before attachment to the skis. This beforehand cushioning protects the ski surfaces from damage during the attachment process and throughout use, preventing harmful effects without requiring complex protective mechanisms or additional steps during operation.
Solution Approach 2:
The squeeze plate assembly combines metal or rigid material for structural integrity with cork material for protective cushioning. This composite construction provides both the mechanical strength needed for secure attachment and the protective qualities needed to prevent ski damage, achieving multiple functions without increasing complexity.
3Reliability
If spring assemblies are used to hold the braking bar in tension, then braking reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The spring assembly is designed to automatically maintain tension on the braking bar through its inherent elastic properties. The spring self-regulates the tension force, eliminating the need for complex adjustment mechanisms or pre-tensioning procedures during manufacturing and assembly. The system serves itself by using the spring's natural characteristics to maintain reliable braking bar tension.
