Wall Connection Box Fastening for Adjustable Axial Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall installation connection box units lack flexibility in axial level adjustment and accessibility for user operation, particularly after installation, which limits their usability and manufacturing efficiency.
Innovation Solution
A wall installation connection box unit design featuring a functional surface body with a connection device that allows for releasable fastening to the base portion at different axial levels, with an actuation interface located on the side of the functional surface body facing away from the base portion, enabling user-operable movement between released and fastened positions, and incorporating rotatable and selectively positionable connection bodies for enhanced accessibility and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connection box unit is designed with a fixed axial level structure, then the manufacturing process is simpler, but the flexibility in adjusting the axial level post-installation is reduced
Solution Approach 1:
The connection body is designed to be movable between different axial positions relative to the base portion, allowing the functional surface body to be fastened at various axial levels. This dynamic positioning capability enables post-installation adjustment while maintaining a relatively simple overall structure through the use of a sliding or adjustable connection mechanism.
Solution Approach 2:
The connection device is divided into separate components: a connection structure on the base portion and a movable connection body. This segmentation allows independent adjustment of the connection body to different axial positions while keeping the base portion structure simple, thus achieving flexibility without excessive complexity.
2Ease of operation
If the actuation interface is located on the base portion side, then the fastening mechanism is more compact, but the accessibility for user operation after installation is reduced
Solution Approach 1:
The actuation interface is positioned on the functional surface body, which extends outward from the base portion. This spatial arrangement places the actuation interface in a different dimension (radially outward) from the base portion, making it accessible to users after installation while maintaining a compact overall structure through the integrated design of the functional surface body.
3Productivity
If the functional surface body is permanently fastened to the base portion, then the manufacturing process is simpler and faster, but the ability to adjust axial level and reposition is lost
Solution Approach 1:
The connection device employs a movable connection body that can be positioned at different axial levels and secured in place. This dynamic fastening mechanism allows for quick adjustment during installation to achieve the correct axial position, and once positioned, provides secure fastening. The system maintains both installation efficiency and repositioning capability through its adjustable locking mechanism.
Solution Approach 2:
The connection body can be preliminarily positioned at the desired axial level before final fastening. This preliminary positioning capability allows installers to adjust the axial level as needed, and then secure the position, combining the benefits of adjustable positioning with efficient final installation.
4Adaptability or versatility
If multiple connection structures are provided for different axial levels, then the adjustability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
Instead of providing multiple separate connection structures for different axial levels, the invention uses a single movable connection body that can be positioned at various axial levels along the base portion. This dynamic positioning approach achieves axial level variability without requiring multiple discrete connection structures, thereby simplifying manufacturing while maintaining adjustability.
Solution Approach 2:
The movable connection body serves multiple functions: it can be positioned at different axial levels, secured in place, and reused for repositioning. This multi-functional design eliminates the need for multiple specialized connection structures for different axial levels, reducing manufacturing complexity while providing the required versatility.
