Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple lever actuating element is used to press directly on the release point, then the device structure is simple, but considerable force is required to release the gas spring and the release force is difficult to control
Solution Approach 1:
The patent employs a lever mechanism with movable components that can dynamically adjust the force application. The lever system includes a lever arm that pivots to provide mechanical advantage, transforming the actuating force into a controlled release force on the gas spring trigger, enabling easy operation while maintaining manageable actuating forces
Solution Approach 2:
The lever mechanism serves as an intermediary between the actuating element and the gas spring trigger. This intermediate lever system translates and controls the force transmission, providing force multiplication and directional control to achieve regulated release forces without requiring the actuating element to directly press on the trigger
2Reliability
If a through recess with internal thread is used for gas spring connection, then the connection is secure, but the device occupies more space and requires additional components like lock nuts
Solution Approach 1:
The patent combines the connection recess and locking function into a single integrated housing structure. The recess in the housing serves both as the mounting interface for the gas spring and as the locking mechanism, eliminating the need for separate lock nuts or additional securing components, thereby reducing space while maintaining connection reliability
Solution Approach 2:
The housing recess is designed to perform multiple functions: it provides structural support for the gas spring connection, acts as a locking mechanism through its geometric constraints, and serves as a mounting interface. This multi-functional design eliminates the need for dedicated separate components, reducing overall device volume while ensuring reliable connection
3Ease of operation
If complex lever mechanisms are used to reduce release forces, then the release force can be controlled, but the device complexity increases and space requirements increase
Solution Approach 1:
The lever mechanism is segmented into distinct functional components: a lever arm with defined pivot points, a trigger engagement section, and an actuating connection section. This segmentation allows each component to perform its specific function efficiently, reducing overall complexity while maintaining force control capabilities through the coordinated action of simplified individual elements
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 reliable, space-efficient, and easily adaptable gas spring operation with reduced assembly complexity and improved safety, facilitating use in diverse geometric conditions.
Implementation Method 1
designed as a force- and/or displacement-translating lever arrangement with an actuating lever which is operatively connected to the actuating device, and at least one trigger lever which acts on the trigger and which interacts directly or indirectly with the actuating lever
Implementation Method 2
Gas springs are known in a wide variety of practical designs. Many gas springs incorporate an integrated valve system, allowing the gas spring to be continuously locked or fixed in any position. The piston is sealed against a pressure tube, separating two gas chambers.
