Rod-Shaped Counterpart for Thin-Walled Panel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mounting a counterpart behind a thin-walled panel, especially in narrow or hard-to-reach spaces, is challenging due to difficulties in aligning and securing the counterpart, leading to potential detachment and local deformations during fastener installation.
Innovation Solution
A device with a rod-shaped counterpart and an auxiliary assembly part that can be fixed to the counterpart on the front side of the panel, allowing it to be clamped and aligned on the back side, ensuring secure positioning and preventing detachment during assembly, with adhesive elements for temporary fixation and a flexible guide element for easy alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the counterpart is mounted on the back side of the thin-walled panel in narrow or hard-to-reach spaces, then the fastener can be securely connected to the panel, but it becomes difficult to align and position the counterpart accurately
Solution Approach 1:
An auxiliary assembly part is introduced as an intermediary component that can be fixed to the counterpart and placed on the front side of the panel. This auxiliary part serves as a mediator that allows the counterpart to be clamped and aligned from the accessible front side, rather than requiring direct manipulation from the inaccessible back side. The auxiliary assembly part includes alignment features and clamping mechanisms that enable precise positioning of the counterpart through the panel opening.
Solution Approach 2:
Instead of attempting to align and position the counterpart from the back side of the panel (where space is limited), the alignment process is inverted by working from the front side. The auxiliary assembly part is attached to the counterpart, extended through the panel opening, and aligned on the front side where adequate working space is available. This inversion of the alignment approach transforms an inaccessibile back-side operation into an accessible front-side operation.
2Stability of the object's composition
If the counterpart is secured with a thread or wire from the back side, then it can be held during assembly, but reliable positioning and alignment are hardly possible
Solution Approach 1:
The auxiliary assembly part acts as a mediator that provides both stabilization and alignment functionality. It includes clamping elements that secure the counterpart to the panel (providing stability) and alignment features such as guide pins or positioning surfaces that ensure accurate positioning. By integrating both functions into the auxiliary part that operates from the front side, the patent simultaneously achieves stable securing and precise alignment, resolving the contradiction between these two requirements.
3Ease of operation
If the counterpart is held by a user during assembly, then it can be positioned, but it may detach and fall down, requiring realignment
Solution Approach 1:
The auxiliary assembly part provides self-service functionality by automatically clamping and securing the counterpart to the panel once positioned. The clamping mechanism may include spring-loaded elements, cam actions, or threaded fasteners that automatically engage and lock the counterpart in place without requiring continuous manual holding. This self-securing mechanism ensures the counterpart remains reliably positioned throughout the assembly process, eliminating the need for user intervention to prevent detachment.
4Object-affected harmful factors
If a large-area counterpart is used to distribute forces, then local deformations are prevented, but mounting in narrow spaces becomes more difficult
Solution Approach 1:
The mounting system is segmented into two distinct components: the counterpart that remains on the back side of the panel (providing the large-area force distribution function), and the auxiliary assembly part that is attached to the counterpart and extends through the panel opening to the front side (providing the alignment and clamping functions). This segmentation allows the large-area counterpart to maintain its force-distributing geometry while the auxiliary part handles the difficult mounting operations from the accessible front side, thereby resolving the contradiction between these two requirements.
