Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joint structures that combine objects using screws or fasteners fail to allow for subsequent movement or separation, limiting their practical application.
Innovation Solution
A joint structure comprising a body part and an actuating piece with movable joint parts that can perform vertical, lateral, or rotational movements, equipped with elastic elements and stop parts, enabling the combination and separation of objects through controlled movement and elastic forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws or fasteners are used to combine objects, then the objects can be securely combined, but they cannot be moved or separated after combination
Solution Approach 1:
The joint structure employs a dynamic locking mechanism where the actuating piece can transition between locked and unlocked states. The elastic element provides continuous dynamic force to maintain engagement, while the movable configuration allows the joint to adapt between fixed and mobile states, resolving the contradiction between secure combination and subsequent movability.
Solution Approach 2:
The joint structure is divided into separable components: a body part, an actuating piece, and a fastening part. This segmentation allows the fastening part to be independently engaged or disengaged from the body part through the actuating piece, enabling secure combination when engaged and easy separation when disengaged, thus achieving both reliability and adaptability.
2Device complexity
If a fixed joint structure is used, then the structure is simple and stable, but it lacks versatility for different movement requirements
Solution Approach 1:
The joint structure is designed with multi-functional capability through the actuating piece that can perform multiple operations: pushing the fastening part to engage for secure combination, releasing it for separation, and enabling rotational or lateral movements. This single component handles multiple functions that would otherwise require separate mechanisms, maintaining simplicity while achieving versatility.
Solution Approach 2:
The joint structure utilizes parameter changes in the elastic element's force and the actuating piece's position to achieve different operational states. By changing the engagement parameter of the fastening part with the body part, the system transitions between locked and unlocked states, and by changing the positional parameter through lateral or rotational movement, it achieves different movement capabilities without increasing structural complexity.

AI summary
A joint structure, a joint module and a method of assembling a joint structure on an object. The joint structure includes a body part and an actuating piece. The actuating piece combines movably with the body part, the actuating piece has a first joint part, the first joint part is located outside of the body part, the first joint part can carry out a vertical movement, lateral movement or rotational movement. Accordingly, the body part of the disclosure can go with the actuating piece or the first joint part, and combine to the first object and the second object, or disengage from the first object and the second object for achieving the effect of combining or separating at least two objects.
