Sliding Accessory Mount With Elastic Locking for Shock Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for removable accessories on sport equipment or vehicles fail to securely attach and detach accessories during strong shocks, such as those experienced in ice-skating, while maintaining ease of operation.
Innovation Solution
A mounting device with a base plate and a support part that slide relative to each other along a longitudinal direction, featuring a locking tooth and opening, and an elastic organ to maintain engagement, allowing for secure attachment and effortless detachment through a simple unlocking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a weak locking force is used to enable easy operation, then the mounting device can be easily mounted and detached, but the accessory may be accidentally released during strong shocks
Solution Approach 1:
The locking mechanism uses a resilient element that provides dynamic locking force. The resilient nature allows the system to adapt between easy operation during normal use and secure locking during shocks, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The locking mechanism is segmented into a resilient element and a rigid structure. The resilient element provides the locking force while the rigid structure provides the locking interface, allowing independent optimization of each component for its specific function.
2Reliability
If a complex mounting scheme with screws is used, then the accessory can be securely attached, but the mounting and detaching operations become difficult and time-consuming
Solution Approach 1:
The traditional screw-based mechanical fastening system is replaced with a sliding resilient locking mechanism. This substitution maintains secure attachment through the resilient locking force while enabling simple one-handed operation for mounting and detaching.
Solution Approach 2:
The dynamic resilient locking mechanism replaces static screw fastening, allowing the locking force to be applied automatically during sliding insertion while maintaining ease of operation through simple linear motion rather than threaded rotation.
3Reliability
If the resilient element provides strong locking force, then the accessory remains secure during shocks, but excessive force is required to manually release the locking mechanism
Solution Approach 1:
The resilient element provides strong locking force during normal operation and shocks, but the same resilient nature allows easy release when sufficient force is applied in the opposite direction, resolving the contradiction between strong locking force and ease of release.
Solution Approach 2:
The locking and releasing functions are achieved through the same resilient element by applying force in opposite directions, eliminating the need for separate mechanisms for locking and releasing while maintaining both strong security and ease of operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a secure hold during shocks and easy mounting/detaching operations, reducing the risk of accidental release and requiring less manual effort compared to prior art designs.
Implementation Method 1
an elastic organ bearing said locking tooth and adapted to apply an elastic force on the rigid structure of the other main part, essentially parallel to said locking direction, so as to keep the locking tooth engaged in the locking opening
Implementation Method 2
Each of said two main parts comprises a rigid structure, said rigid structure comprising a pair of lateral guiding surfaces arranged so as to slide against the lateral surfaces of the other main part during said relative sliding movement
