Movable Support Structure Resilient Retaining Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable support structures fail to securely maintain the connection between components, leading to potential disengagement due to manufacturing or assembly errors, especially in devices with interlock connectors.
Innovation Solution
A movable support structure featuring a first component with a movable supporting portion and a second component with a supported portion, where the retaining/restricting portion is resiliently deformable to be retracted from a catching posture, and a deformation restricting portion prevents the retaining/restricting portion from releasing, ensuring the first component remains securely attached to the second component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a movable supporting portion supports a supported portion with relative movability, then the ease of operation is improved, but the reliability deteriorates due to potential disengagement
Solution Approach 1:
The retaining/restricting portion is designed to proactively prevent disengagement before it occurs. The resilient portion creates a preliminary restraining force that counteracts any forces that might cause the supported portion to detach, while still allowing controlled movement during normal operation.
Solution Approach 2:
The retaining/restricting portion incorporates a resilient element that can dynamically adjust its state. The resilient portion can elastically deform to accommodate movement during operation, then return to its restraining position to prevent disengagement, providing adaptive behavior that balances movability and reliability.
2Ease of operation
If a retaining/restricting portion is made resiliently deformable to allow insertion, then the ease of operation is improved, but the reliability worsens due to potential release
Solution Approach 1:
The resilient portion provides dynamic behavior during insertion by elastically deforming to allow the supported portion to pass through, then automatically returning to its restraining position to secure the connection. This dynamic response enables easy insertion while maintaining reliable retention.
Solution Approach 2:
The resilient portion acts as a cushioning element that absorbs the energy and force of insertion. By deforming elastically during insertion, it cushions the engagement process and then maintains a stable restraining force to prevent accidental release during operation.
3Ease of manufacture
If the retaining/restricting portion can be easily retracted for assembly, then the ease of manufacture is improved, but the reliability deteriorates due to potential disengagement
Solution Approach 1:
The resilient portion provides automatic dynamic locking through elastic deformation. During assembly, the resilient portion naturally deforms to allow insertion, then self-locks in the restraining position without requiring additional fastening operations, achieving both ease of manufacture and high reliability.
Solution Approach 2:
The resilient portion performs self-service by automatically assuming the restraining position after insertion without requiring external intervention. The elastic nature of the resilient portion causes it to self-lock into place, eliminating the need for separate securing steps while ensuring reliable connection.

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 solution effectively prevents the first component from coming off the second component, maintaining a stable connection even under varying conditions and errors, thus enhancing the reliability of the support structure.
Implementation Method 1
the retaining/restricting portion is resiliently deformable in a direction to be retracted from a relative passage path for the receiving portion when the supported portion is inserted into the movable supporting portion from a catching posture
Implementation Method 2
the deformation restricting portion restricts resilient deformation of the retaining/restricting portion in a direction to be retracted from the catching posture
