Housing With Window Portion For Jumper Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting terminal cover designs face challenges in easily attaching and detaching jumper members due to the complexity of connecting them to inner terminals on densely mounted electronic circuit substrates, often resulting in damage to peripheral components and increased labor and risk of assembly errors.
Innovation Solution
A housing design featuring a main body with a distinct window portion opposed to the jumper, allowing for easy attachment and detachment without contacting other electronic parts, and a cover portion to manage the window, reducing the need to detach surrounding substrates and minimizing contact with electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the jumper member is connected to the inner connecting terminal on the electronic circuit substrate, then the alternative circuit is formed, but the working property is low due to difficulty in connection and risk of damaging peripheral electronic parts
Solution Approach 1:
The housing is segmented into a main body portion and a lid portion that can be separated. The lid portion covers the opening portion of the main body portion, creating a protected access point to the jumper member while keeping the electronic circuit substrate secure in the main body. This segmentation allows the jumper to be accessed through the lid opening without exposing the entire substrate to potential damage.
Solution Approach 2:
The lid portion acts as an intermediary structure that provides controlled access to the jumper member. By opening the lid, the jumper can be attached or detached through the opening portion without direct exposure to the entire electronic circuit substrate, thereby preventing accidental contact with and damage to peripheral electronic parts while still enabling reliable circuit connection.
2Reliability
If the jumper member is attached to the electronic circuit substrate, then the alternative circuit is formed, but electronic circuit substrates around the jumper need to be detached which requires time and labor
Solution Approach 1:
The housing structure is divided into separable lid and main body portions. The jumper member is positioned such that it can be accessed through the opening in the lid without requiring removal of the entire electronic circuit substrate or surrounding components. This segmentation enables the jumper to be independently attached or detached, significantly reducing maintenance time and improving productivity.
Solution Approach 2:
The jumper member is extracted as a separate, independently accessible component through the lid opening. This allows the jumper to be removed and reattached without detaching the electronic circuit substrates around it, eliminating the time-consuming process of complete substrate removal and reassembly while maintaining circuit configuration flexibility.
3Ease of operation
If the electronic circuit substrates are detached for jumper attachment, then the jumper can be accessed, but the electronic circuit substrates and wires may be assembled at inappropriate positions causing failure or malfunction
Solution Approach 1:
The housing is divided into a stationary main body portion containing the electronic circuit substrate and a removable lid portion. The jumper member is accessed through an opening in the lid without removing the substrate from the main body. This segmentation ensures the substrate remains in its correct positioned throughout the jumper attachment process, eliminating the risk of misassembly while maintaining easy jumper accessibility.
Solution Approach 2:
The lid portion serves as an intermediary access point that allows the jumper to be reached and manipulated without disturbing the electronic circuit substrate. By providing this intermediate access path, the substrate and its wires remain securely in place, ensuring assembly accuracy is maintained while still enabling straightforward jumper attachment operations.
