Solution Overview

Problem

Automatic cycle storage systems are vulnerable to vandalism due to lack of effective resistance mechanisms, allowing unauthorized access and damage.

Innovation Solution

The system incorporates a second attachment member on the locking station with three degrees of freedom in rotation, elastically urged towards a rest position, providing an increasing return force when attempting to be displaced, and an abutment member that prevents locking when an anti-theft device is immobilized, enhancing security without increasing weight or size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the second attachment member is rigidly fixed to the support, then the cycle is securely locked, but the system becomes vulnerable to vandalism and damage

Engineering Contradiction:
ImprovesecurityVSAvoidvandalism resistance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The second attachment member is made movable with three rotational degrees of freedom instead of being rigidly fixed. It can pivot dynamically to absorb vandalism forces while maintaining locking capability through elastic restoration to its original position.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Elastic means (such as springs or elastomers) are incorporated to provide beforehand cushioning against vandalism forces. These elastic elements absorb impact energy and exert restoring forces to return the second attachment member to its locking position after disturbance.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Object-affected harmful factors

If the second attachment member is made movable to resist vandalism, then vandalism resistance improves, but the locking security may be compromised

Engineering Contradiction:
Improvevandalism resistanceVSAvoidlocking security
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

Elastic means are pre-configured to provide restoring force that automatically returns the second attachment member to its locking position after being displaced by vandalism attempts, thereby maintaining locking security despite movability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The elastic means convert the harmful displacement forces from vandalism into beneficial restoring forces that actively return the locking member to its secure position, transforming the vulnerability of movability into a protective feature.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Object-affected harmful factors

If elastic means are added to provide restoring force, then vandalism resistance improves, but the device complexity increases

Engineering Contradiction:
Improvevandalism resistanceVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Elastomer pads or flexible elastic elements are used instead of complex mechanical spring systems. These flexible components provide the necessary restoring force while occupying minimal space and adding little structural complexity to the locking station.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

An automatic cycle storage system comprising cycles (1) and a fixed infrastructure having a plurality of locking stations (7) adapted to receive and lock each cycle. Each cycle has a first locking member which locks onto a second locking member (8) articulated on the locking station with at least two degrees of rotational freedom.
