Two-Way-Opening Storage Box Lid Decelerator and Restrictor Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-way-opening storage boxes face challenges in decelerating lid closure speed, maintaining structural integrity, and preventing accidental opening when sliding, due to complex designs and increased weight, which lead to noise issues and potential damage.
Innovation Solution
A two-way-opening storage box design featuring a link mechanism with restrictors to prevent swinging when fully slid, a decelerator for controlled closure, and a circumventer to prevent sliding lock reengagement, allowing for reliable operation and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If decelerators are provided around both right and left swing shafts to decelerate lid closure speed, then noise is reduced, but device complexity and weight increase
Solution Approach 1:
The patent combines the deceleration functions for both swing shafts into a single decelerator unit. The decelerator includes a common housing that accommodates both deceleration mechanisms, with the housing serving multiple functions: providing structural support, containing the deceleration mechanisms, and reducing overall component count. This merging approach reduces device complexity while maintaining noise reduction benefits.
Solution Approach 2:
The decelerator housing serves multiple functions: it acts as the structural housing for the deceleration mechanisms, provides mounting surfaces for the swing shafts, and contributes to the overall structural integrity of the lid assembly. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while maintaining the noise reduction function.

3Reliability
If the lid structure is made complex to prevent accidental opening when sliding, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent incorporates a restrictor mechanism that prevents the lid from swinging when it is in the fully slid position. The restrictor includes a restrictor arm that engages with a restrictor protrusion on the lid, creating a mechanical interlock that prevents accidental opening. This preliminary anti-action is built into the structure, providing reliability without requiring complex control systems or additional sensors.

AI summary
A two-way-opening storage box includes a box body, a lid, a link mechanism, and a restrictor. The lid includes a base member, and a movable member. The base member covers the box body. The movable member is held onto the base member slidably. The restrictor is disposed in at least one of the base member and the movable member, and is capable of restricting the link mechanism from being actuated under such a condition as the movable member has fully slid, and/or under such another condition as the movable member is sliding
