Hook Module Elastic Arm Restoring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hook modules for electronic devices require additional assembly steps and occupy more space due to the need for a spring, which can also fall off during operation, leading to instability.
Innovation Solution
A hook module with a base and a hook body featuring elastic arms that deform and provide a restoring force, eliminating the need for a spring by using positioning pillars and abutting portions to facilitate movement and return to the original position, integrated with a push button for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is used to provide restoring force for the hook module, then the hook can return to original position, but the assembly complexity increases and the spring may fall off during operation
Solution Approach 1:
The patent removes the spring component from the hook module design. Instead of using a separate spring element, the restoring force is generated by the elastic deformation of the hook body itself through its elastic arms and abutting portions. This extraction of the spring simplifies the assembly process while maintaining the essential function of returning the hook to its original position.
Solution Approach 2:
The patent integrates the spring function directly into the hook body structure. The elastic arms with abutting portions are designed to deform and provide restoring force as an integral part of the hook assembly, eliminating the need for a separate spring component. This merging reduces the number of parts and assembly steps while ensuring the spring cannot fall off during operation.
2Reliability
If a spring is added to the hook module for restoring function, then the hook can restore, but the space occupation increases
Solution Approach 1:
The restoring mechanism is merged into the hook body itself through the elastic arms. The abutting portions are positioned on the elastic arms, and when the hook is pressed, these portions deform elastically to provide the restoring force. This integration eliminates the need for additional space-consuming spring components while maintaining the restoring function.
Solution Approach 2:
The patent uses elastic arms that function as flexible structural elements. These elastic arms can deform under applied force and return to their original shape, providing the restoring mechanism within a compact form factor. The flexibility of the elastic arms allows the restoring function to be achieved without adding significant volume to the hook module.
3Ease of operation
If the hook structure includes an extending portion at the end, then the hook can engage with the cover, but the operation stroke increases and space is occupied
Solution Approach 1:
The patent changes the engagement mechanism from linear extension to a different dimensional approach. Instead of using a long extending portion that increases operation stroke, the hook body engages with the cover through a pressing motion that utilizes the elastic deformation of the arms. This dimensional change in the engagement approach reduces the operation stroke while maintaining effective hook-cover engagement.

Function Achieved in This Case
Simplifies the assembly process, reduces space occupation, and enhances stability by eliminating the need for a spring, while maintaining the hook's functionality and restoring mechanism.
Implementation Method 1
the two elastic arms deformed, and an elastic restoring force of the two elastic arms drives the hook body to restore

AI summary
A hook module of an electronic device is disclosed. The hook module includes a base and a hook body. The base includes two positioning pillars and a side board, and the hook body is located on the base with one end passing through the side board. The hook body includes two elastic arms located at two edges of the hook body, respectively, and each of the elastic arms includes an abutting portion. When the hook body is moved by force applied on it, the two abutting portions abut against the two positioning pillars. The two positioning pillars and the two abutting portions move relative to each other to make the two elastic arms deformed, and an elastic restoring force generated from the two elastic arms drives the hook body to restore.
