Foldable Enclosure Hinge With Nonlinear Load Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with foldable housings lack sufficient holding force to maintain the open and closed states due to mechanical losses from multiple components between the holding device and the enclosure.
Innovation Solution
A hinge holding device with a suction mechanism that includes a load generator within one enclosure, utilizing a slider cam and spring bracket to generate a non-linear load between the base frame and enclosure, ensuring secure open and closed states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple components are used in the holding device, then the structure can support the enclosure, but mechanical loss occurs and holding force is insufficient
Solution Approach 1:
The invention extracts and eliminates the intermediate components that cause mechanical loss from the force transmission path. By directly connecting the spring element to the enclosure and base frame, the patent removes the multiple components that were causing energy loss, thereby improving holding force efficiency.
Solution Approach 2:
The spring element is pre-loaded to generate holding force before the enclosure reaches the open or closed state. This preliminary action ensures that the maximum holding force is available when needed, compensating for any remaining mechanical losses in the hinge mechanism.
2Strength
If a simple structure with few parts is used, then manufacturing is easier, but sufficient holding force cannot be provided
Solution Approach 1:
The invention merges the holding function and the force generation function into a single integrated structure. The spring element directly connects the enclosure to the base frame, combining what would traditionally be separate components into one unified mechanism that provides both structural support and holding force.
Solution Approach 2:
The spring element serves multiple functions simultaneously: it provides holding force, acts as a structural connector, and compensates for mechanical losses. This multi-functionality allows the patent to achieve sufficient holding force with a minimal number of parts.
3Reliability
If traditional holding devices are used, then the structure is simple, but the open and closed states cannot be maintained firmly
Solution Approach 1:
The spring element automatically adjusts and maintains holding force throughout the enclosure's movement. The elastic deformation of the spring provides continuous force adjustment, ensuring reliable holding in both open and closed states without requiring complex control mechanisms or multiple adjustment components.

AI summary
A hinge holding device for firmly holding a pair of enclosures in an open or closed state has a base frame sandwiched between the pair of enclosures and supporting the pair of enclosures in an open or closed state, and a suction mechanism having a load generator disposed within at least one of the pair of enclosures. The suction mechanism generates a non-linear load between the base frame and one of the enclosures to maintain the open and closed state of one of the enclosures with respect to the base frame.
