Slide Cover Linking Mechanism with Push Aid and End Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide cover linking mechanisms often result in violent deceleration and potential damage to components due to lack of effective buffering at the final stage of sliding travel, and require excessive user force to overcome resistance from buffering units, making operation inconvenient.
Innovation Solution
A slide cover linking mechanism with both push aid and end buffering effects, featuring a seat body with slide guide sections, elastic members, and a movable member that stores and releases energy to provide a smooth opening and closing action while minimizing impact through a combination of first and second elastic members and a turning section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a buffering unit is added to provide resistance against sliding, then the buffering effect is improved, but the ease of operation deteriorates due to greater force required
Solution Approach 1:
The buffering function is segmented into two distinct elastic members: the first elastic member provides buffering at the beginning and end of sliding travel, while the second elastic member provides buffering only at the end stage. This segmentation allows each member to be optimized for its specific function, with the second member having smaller elastic force specifically tuned for end-stage buffering without interfering with overall operability.
Solution Approach 2:
The buffering force is applied locally at different stages of sliding travel rather than uniformly throughout. The first elastic member acts locally at the start and end points, while the second elastic member acts locally only at the final stage. This local application of buffering force ensures that resistance is provided only where needed, maintaining ease of operation during most of the sliding行程 while still protecting against impact at the critical end stage.
2Reliability
If elastic elements are placed at the end for buffering, then the buffering effect is improved, but the slide cover is frequently impacted due to violent deceleration
Solution Approach 1:
The first elastic member performs preliminary buffering action at the beginning of the sliding travel, storing elastic potential energy as the slide cover moves away from its initial position. This preliminary action prepares the system for the end-stage buffering by the second elastic member, ensuring a more controlled deceleration profile and reducing violent impact at the final stage.
Solution Approach 2:
The second elastic member is pre-positioned and pre-loaded to provide cushioning specifically at the end stage of sliding travel. By having this dedicated cushioning mechanism ready in advance, the system can gradually absorb the kinetic energy of the sliding cover as it approaches the end of its travel, preventing violent deceleration and impact damage to components.
3Object-affected harmful factors
If a buffering unit is added between the main body and slide cover, then the impact avoidance is improved, but the device complexity increases
Solution Approach 1:
The first elastic member serves multiple functions: it provides buffering at both the beginning and end of the sliding travel, and it also assists in returning the slide cover to its initial position. The second elastic member, while specialized for end-stage buffering, works in conjunction with the first member to create a comprehensive buffering system. This multi-functionality reduces the need for additional separate buffering mechanisms, thereby limiting the increase in device complexity.
4Reliability
If the second elastic member provides smaller elastic force, then the end buffering effect is improved, but the overall driving force is reduced
Solution Approach 1:
The elastic force characteristics of the two members are dynamically optimized for different stages of operation. The first elastic member has larger elastic force to handle the main buffering and return functions during most of the sliding行程. The second elastic member has smaller, specifically tuned elastic force that activates only at the critical end stage. This dynamic differentiation ensures that the smaller force of the second member does not compromise overall driving force, as it supplements rather than replaces the primary elastic member during most operations.

Function Achieved in This Case
The mechanism reduces the need for excessive user force and minimizes the risk of component damage by providing a smooth sliding action and effective buffering at the end of the travel, ensuring stable operation and assembly of large-size electronic products.
Implementation Method 1
at least one first elastic member, a first end of the first elastic member being pivotally connected with a section in the receiving space near the turning section, a second end of the first elastic member being pivotally connected with a middle section of the slide seat, whereby the first elastic member serves to apply a force to the slide seat for driving the slide seat to slide toward two end sections of the second slide guide section
Implementation Method 2
at least one second elastic member for providing an elastic force smaller than that of the first elastic member in operation, a first end of the second elastic member being located in the receiving recess, a second end of the second elastic member being connected with a slide guide member slidable within the third slide guide section
