Attachment member, member attachment structure, and member attachment method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment systems for electronic devices and members face a reduction in connection strength due to protrusions not corresponding to the target member's holes, leading to gaps and interference, which compromises the attachment's stability.
Innovation Solution
An attachment member with a first protrusion engaging with a target member's specific part and a second protrusion that retracts via an advancement and retraction mechanism to prevent interference and ensure close contact, enhancing the connection strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple positioning protrusions are provided on the support rail to fit different rack frame types, then the versatility of the support rail is improved, but the connection strength between the support rail and rack frame is reduced due to gaps formed by non-corresponding protrusions
Solution Approach 1:
The invention makes the protrusions dynamic by enabling them to advance and retract. The protrusions can advance to engage with positioning holes in different rack frame types, and retract when not needed to avoid forming gaps. This dynamic adjustment resolves the contradiction by allowing the support rail to maintain both versatility (adapting to different rack types) and connection strength (avoiding gaps when protrusions are retracted).
Solution Approach 2:
The invention segments the attachment function by providing multiple independent protrusions that can operate independently. Each protrusion can be advanced or retracted based on whether it corresponds to a positioning hole in the rack frame. This segmentation allows the system to maintain versatility while preventing the harmful effect of non-corresponding protrusions forming gaps, thereby preserving connection strength.
2Reliability
If protrusions are made larger to ensure engagement with positioning holes, then the reliability of engagement is improved, but the protrusions interfere with rack frame surfaces when not engaged, forming gaps and reducing attachment strength
Solution Approach 1:
The invention resolves this contradiction by making the protrusions dynamic rather than static. The protrusions can advance to engage with positioning holes (ensuring reliable engagement when needed) and retract to avoid interfering with the rack frame surface (preventing gap formation when not needed). This dynamic capability allows the protrusions to maintain larger dimensions for reliable engagement while eliminating the harmful interference effect.
3Adaptability or versatility
If the support rail is designed to fit multiple rack frame types with different positioning holes, then the adaptability is improved, but the end portion of the support rail cannot maintain close contact with the rack frame, reducing connection strength
Solution Approach 1:
The invention resolves this contradiction by enabling the protrusions to dynamically adjust their positions. When the support rail is attached to a specific rack frame type, the corresponding protrusions advance to engage with the positioning holes, while non-corresponding protrusions retract to avoid interference. This allows the end portion of the support rail to maintain close contact with the rack frame surface, ensuring strong connection while preserving adaptability to different rack frame types.
Solution Approach 2:
The invention applies preliminary action by pre-configuring multiple protrusions in advance, each corresponding to different rack frame types. Before attachment, the system is prepared with all possible protrusion configurations available. During attachment, the appropriate protrusions are advanced while others are retracted, ensuring optimal engagement and close contact without requiring complex real-time adjustments.
