Rotating Chassis Door Latch for Multi-Angle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latch systems for information handling systems face challenges in accommodating door operation from any direction, leading to suboptimal protection and potential damage to peripherals and ports.
Innovation Solution
A latch system with a rotatable door panel coupled to the chassis, featuring a base with spaced arms and a torsion spring, allowing movement from 0 to 90 degrees, and a rotary damper for controlled rotation and translation, enabling the door panel to open and close while preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional latch mechanism is used, then the door can be secured in a closed position, but it cannot accommodate door operation from any direction (0 to 90 degrees movement)
Solution Approach 1:
The latch mechanism incorporates a rotary damper and torsion spring that enable dynamic movement across a 0 to 90 degree range, allowing the door to be secured at multiple angles rather than a fixed position. This dynamic capability resolves the contradiction by providing versatile door operation while maintaining a relatively simple mechanical structure.
Solution Approach 2:
The latch system is divided into distinct functional components: a base, a movable arm, a rotary damper, and a torsion spring. This segmentation allows each component to handle specific aspects of the movement and securing function, enabling multi-directional operation without requiring an overly complex integrated mechanism.
2Adaptability or versatility
If a latch system with multi-directional movement capability is designed, then door operation from any direction is accommodated, but the design becomes difficult to optimize
Solution Approach 1:
The latch mechanism is designed as a universal system that can accommodate door operation from any direction within the 0 to 90 degree range. The rotary damper and torsion spring combination provides a standardized approach that simplifies design optimization while maintaining multi-directional capability, as the same basic mechanism handles all angular positions.
3Adaptability or versatility
If the door panel is allowed to move freely from 0 to 90 degrees, then versatility is improved, but secure engagement becomes more difficult to maintain
Solution Approach 1:
The torsion spring provides automatic restoring force that maintains secure engagement throughout the door's movement range. As the door moves from 0 to 90 degrees, the spring continuously applies torque to keep the latch arm engaged with the door panel, eliminating the need for additional active control mechanisms and ensuring reliable engagement across all positions.
Solution Approach 2:
The rotary damper provides damping force that controls the door's movement and prevents excessive forces during operation. This beforehand cushioning effect ensures that the latch mechanism remains engaged securely throughout the range of motion, accommodating versatile door operation while maintaining reliable engagement through controlled energy dissipation.

AI summary
A rotating door panel is coupled to a chassis. A pair of arms extend from a base connected to the chassis. The arms are movable between a first configuration and a second configuration. A latch is connected to the chassis, and a stryker connected to the door panel is engageable with the arms. The stryker is operable to angularly approach the latch for engagement with the latch.
