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

VSEngineering 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

Engineering Contradiction:
Improveease of mounting and detachingVSAvoidsecurity during shocks
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvesecure attachmentVSAvoidmounting and detaching operations
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvesecurity during shocksVSAvoidforce required to release
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation
