Wheeled Platform Locking Indicator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheeled platforms lack a clear indication of their locking state, making it difficult for users to determine whether the locking device is engaged with a wall-mounted striker.
Innovation Solution
Incorporating a locking device with an interlocked displacement member and an operation member that are displaceable between locking and non-locking positions, along with a spring that increases elastic deformation, allowing users to visually confirm the locking state through an indicator visible when the interlocked displacement member is at the non-locking position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is added to the wheeled platform, then the platform can be secured to a wall, but the user cannot determine whether the locking device is engaged
Solution Approach 1:
The patent employs visual indicators that change position or become visible to indicate the locking state. The indicator member moves between different positions corresponding to locked and unlocked states, providing clear visual feedback to the user about the current state of the locking device.
Solution Approach 2:
The patent implements a feedback mechanism where the position of the indicator member directly reflects the state of the locking device. When the locking device transitions between locked and unlocked states, the indicator member相应地 moves to provide real-time visual feedback to the user about the current locking status.
2Loss of information
If an indicator system is added to show locking state, then user awareness of locking state improves, but device complexity increases
Solution Approach 1:
The patent combines the indicator function with existing components of the locking mechanism. The indicator member is integrated into the structure of the locking device itself, sharing space and functional elements with the locking mechanism, thereby providing state indication without adding separate complex indicator systems.
Solution Approach 2:
The indicator member serves multiple functions: it indicates the locking state visually while also being mechanically linked to the locking mechanism. This multi-functionality reduces the need for separate dedicated indicator components, thereby limiting the increase in device complexity.
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
Enables users to easily determine the locking state of the wheeled platform by observing the positions of the interlocked displacement member and operation member, ensuring secure engagement and easy release from the wall.
Implementation Method 1
a spring configured to apply an elastic force to the operation member, the spring being configured such that an amount of elastic deformation thereof increases as the operation member is displaced from the second locking position to the second non-locking position

AI summary
A wheeled platform includes: an interlocked displacement member displaceable between a first locking position corresponding to a locking state of a locking device and a first non-locking position corresponding a non-locking state; an operation member displaceable between a second locking position corresponding to the locking state and a second non-locking position corresponding to the non-locking state, the operation member transmitting an operational force to the interlocked displacement member to displace the interlocked displacement member to the first non-locking position; and a spring that applies an elastic force to the operation member.
