Elastic Support with Interlocking Recess for Chassis Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching rubber legs to electronic device chassis, such as laptops, face issues with adhesion degradation over time and complex attachment processes, leading to potential separation of the rubber legs from the chassis.
Innovation Solution
A support system comprising a first elastic member with a recessed portion and a second member with a protruding portion, designed to be fitted together, allowing for easy attachment and secure fitting into the chassis opening, preventing separation through elastic deformation and rib engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If double-stick tape or adhesive is used to attach the rubber leg to the chassis, then the attachment process is simple, but the adhesion decreases over time resulting in separation
Solution Approach 1:
The support is divided into two distinct members: a first elastic member that fits into the chassis opening and a second member with a protruding portion that fits into the recessed portion of the first member. This segmentation allows each component to perform its specific function - the first member provides secure anchoring through elastic deformation while the second member provides additional mechanical interlocking, together solving the adhesion durability problem without complicating the overall attachment process
Solution Approach 2:
The second member with the protruding portion is nested into the recessed portion of the first elastic member, creating a multi-level interlocking structure. This nesting arrangement enhances the overall attachment reliability by adding a second mechanical connection point while maintaining a compact design that does not significantly increase assembly complexity
2Strength
If the rubber leg is thermally fused into a hole in the chassis, then attachment strength is improved, but the attachment operation becomes complicated
Solution Approach 1:
The invention replaces the thermal fusion process with a purely mechanical interlocking system. The first elastic member's recessed portion and the second member's protruding portion create a mechanical snap-fit connection that achieves strong attachment without requiring heat application, thereby maintaining attachment strength while significantly simplifying the attachment operation
Solution Approach 2:
The first elastic member is designed with specific elastic properties that allow it to deform during insertion and then recover to provide continuous holding force. This parameter change from rigid to elastic behavior enables the support to achieve strong attachment through simple insertion and recovery motion, eliminating the need for complex thermal fusion processes
3Ease of operation
If a simple attachment method is used, then the attachment operation is simple, but the support is more likely to separate from the chassis
Solution Approach 1:
The first elastic member is designed to dynamically respond to insertion forces by deforming during the attachment process and then recovering to provide continuous holding force. This dynamic behavior allows the support to be attached through a simple insertion motion while maintaining high attachment stability through the ongoing elastic recovery force that prevents separation
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
The support system provides a secure, easy-to-attach solution that prevents slipping, rattling, and shock absorption, maintaining stability and reducing the likelihood of separation from the chassis.
Implementation Method 1
the first member has elasticity and has the recessed portion, the first member is elastically deformed in a direction where the recessed portion narrows to be able to be easily fitted into the opening
Implementation Method 2
The first member is elastic, and therefore supports the chassis cushion-wise. For example, the action of preventing slipping or rattling of the chassis or absorbing shock is demonstrated
Implementation Method 3
the action of preventing slipping or rattling of the chassis or absorbing shock is demonstrated
Implementation Method 4
after the protruding portion of the second member is fitted into the recessed portion of the first member, the protruding portion of the second member prevents the elastic deformation of the first member in the direction where the recessed portion narrows, and therefore the first member fitted into the chassis can be prevented from falling off from the opening

AI summary
A support can be easily attached to and is less likely to separate from an opening of a chassis of an electronic device. The support has a first elastic member having a recessed portion and configured to be fitted into the opening so that an opening surface of the recessed portion is directed to an inside of the chassis, and a second member having a protruding portion configured to be fitted into the recessed portion of the first member.
