Eccentric Adjustment Mechanism for Ski Boot Clamping Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping closure devices for shoes, such as ski and snowboard boots, are technically complex and expensive due to their fine adjustment mechanisms, which are often thread-like or gear-like, and lack a simple, cost-effective solution for precise, stepless adjustment of clamping force.
Innovation Solution
A toggle fastener device with an eccentric adjustment mechanism that allows for precise, stepless adjustment of the clamping force by connecting the elongated pulling device to an eccentric module, enabling rotational movement to be converted into longitudinal movement, thereby adjusting the clamping length and angle without releasing the device, using fewer components and avoiding unintentional adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If thread-like or gear-like fine adjustment devices are used, then precise adjustment of clamping force is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces complex thread-like or gear-like adjustment mechanisms with a simple elongate pulling device that can be directly adjusted in length. This substitution eliminates the need for intricate mechanical components while maintaining precise adjustment capability through the fundamental tensioning action of the pulling device itself.
Solution Approach 2:
The invention changes the adjustment parameter from rotational movement (threads/gears) to direct linear dimension changes of the pulling device. By making the pulling device itself length-adjustable, the system achieves fine adjustment of clamping force through a simpler parameter change mechanism that reduces overall device complexity.
2Measurement precision
If thread-like or gear-like fine adjustment devices are used, then precise adjustment of clamping force is achieved, but manufacturing cost increases
Solution Approach 1:
The patent replaces complex thread-like or gear-like adjustment mechanisms with a simple elongate pulling device that can be directly adjusted in length. This substitution eliminates the need for intricate mechanical components while maintaining precise adjustment capability through the fundamental tensioning action of the pulling device itself.
Solution Approach 2:
The invention employs a simpler pulling device structure that can be manufactured more economically. By eliminating complex adjustment mechanisms, the overall manufacturing cost is reduced while still achieving the desired precision through the basic tensioning function of the simplified component.
3Ease of operation
If the elongate pulling device is made length-adjustable, then comfortable adjustment of clamping force is enabled, but device complexity increases
Solution Approach 1:
The patent divides the pulling device into multiple segments or sections that can be independently adjusted in length. This segmentation allows for incremental length changes while keeping each individual segment simple in structure, thereby achieving adjustability without proportionally increasing overall device complexity.
Solution Approach 2:
The invention makes the pulling device dynamically adjustable in length, allowing it to adapt to different clamping requirements. This dynamic capability is achieved through a simplified mechanism that enables length modification without requiring complex static adjustment structures.
4Measurement precision
If fine adjustment devices are added to existing clamping closure devices, then precise adjustment of clamping force is achieved, but device complexity and cost increase
Solution Approach 1:
The patent merges the adjustment function directly into the pulling device itself rather than adding separate fine adjustment mechanisms. By combining the tensioning and adjustment functions into a single integrated component, the system achieves precise adjustment capability without increasing overall device complexity through additional separate mechanisms.
Solution Approach 2:
The invention makes the pulling device multi-functional by enabling it to perform both the primary tensioning function and the fine adjustment function. This universality eliminates the need for separate dedicated adjustment devices, thereby achieving precise control while maintaining simplicity in the overall system architecture.
