Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional attachment devices struggle to securely attach electronic devices to thin walls without penetrating them, requiring additional support from pillars, and alignment in a horizontal direction is challenging without specialized tools.
Innovation Solution
An attachment device with a base featuring pin holes arranged at a predetermined angle, secured by pins that distribute the load over a wider area, and a sheet with symmetric openings for aligning and securing multiple devices horizontally, allowing for easy attachment and alignment without needing a level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional attachment devices are used to attach electronic devices to thin walls, then additional support from pillars is required, but this increases device complexity and installation difficulty
Solution Approach 1:
The base is divided into multiple pin holes arranged at different angles, allowing pins to be distributed across different locations and orientations. This segmentation enables the attachment device to securely attach to thin walls without requiring additional pillar support, as the multiple pinned connections collectively provide sufficient structural reliability.
2Manufacturing precision
If conventional attachment devices are used without alignment tools, then horizontal alignment is difficult to achieve, but using specialized tools increases device complexity
Solution Approach 1:
The base incorporates a symmetry axis and symmetrically arranged pin holes that enable self-alignment during installation. The symmetric structure allows the base to naturally align horizontally when mounted, eliminating the need for external alignment tools like levels while maintaining high horizontal alignment precision.
Solution Approach 2:
While the overall structure is symmetric, the pin holes are arranged at specific asymmetric angles relative to the symmetry axis. This controlled asymmetry in hole positioning, combined with the symmetric layout, provides both self-alignment capability and precise horizontal orientation without requiring additional alignment tools.
3Area of stationary object
If pins are inserted perpendicular to the wall surface, then the attachment area is limited, but increasing the pin insertion angle reduces attachment stability
Solution Approach 1:
Different pin holes are designed with different orientation angles relative to the wall surface. This local variation in pin angle allows some pins to penetrate deeper into the wall structure for enhanced stability, while others provide broader distribution across the attachment area. Each pin's orientation is optimized for its specific location, achieving both extended attachment area and maintained stability.
