Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices lack effective safety measures to prevent incorrect operation, particularly when components such as display means, switches, and plug connectors are exposed, leading to potential hazards during transportation and installation.
Innovation Solution
The electrical device features a pivotably mounted cover part with a locking mechanism that includes a pin and guide grooves, allowing for secure attachment to the housing while enabling easy exchange of the locking means, which is designed to be elastic and reusable, thereby enhancing safety by preventing accidental opening or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover part is firmly fixed to the housing, then safety and protection of internal components are improved, but ease of maintenance and replacement of locking mechanism are worsened
Solution Approach 1:
The locking mechanism is segmented into separate components: the locking means (23, 24) and the housing part (14, 25) are designed as separable elements. The locking means can be detached from the housing part, allowing maintenance and replacement without replacing the entire cover assembly, thus maintaining safety while enabling easy repair.
Solution Approach 2:
The locking means (23, 24) are designed to be extractable from the housing part (14, 25). The screw connections allow the locking means to be completely removed from the housing, enabling easy replacement of defective locking components while preserving the housing structure and other functional parts.
2Ease of repair
If the locking means is designed to be elastic and detachable, then ease of repair and replacement are improved, but connection strength and reliability are worsened
Solution Approach 1:
The connection parameters are designed to provide both ease of replacement and sufficient strength. The screw connections allow for controlled tightening torques that ensure strong connection during operation, while the same connection mechanism can be easily loosened and removed for replacement when needed, achieving both goals through parameter optimization.
3Reliability
If the cover part is pivotably mounted with locking means, then safety against incorrect operation is improved, but device complexity is worsened
Solution Approach 1:
The pivotable mounting and locking function are merged into a single integrated mechanism. The cover part (4, 63) is pivotably connected to the housing and simultaneously equipped with locking means (23, 24) that engage with the housing part (14, 25), combining movement and securing functions in one system to reduce overall complexity.
Solution Approach 2:
The cover part assembly serves multiple functions: it protects internal components, provides a pivotable opening mechanism for access, and incorporates locking means to prevent accidental opening. This multi-functionality reduces the need for separate components, thereby managing complexity while enhancing safety.
4Ease of manufacture
If the locking means is clip-connected to the housing part, then ease of manufacture and assembly are improved, but connection strength is worsened
Solution Approach 1:
The clip-connection design incorporates elastic deformation capability in the locking means (23, 24). The material and geometry are designed to allow controlled elastic deflection during assembly and operation, enabling the clip to flex into position and then maintain a strong, reliable connection under operational loads, thus achieving both ease of assembly and connection strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents incorrect operation and damage by ensuring the cover part can be securely locked, protecting internal components and reducing the risk of injury during handling and installation, while allowing for easy maintenance and replacement of the locking mechanism.
Implementation Method 1
the locking means is designed to be elastically deformable, at least in sections
Implementation Method 2
The projection is pressed into the recess by an elastically pretensioned area of the locking means. The advantage here is that the elastic force acting on the locking means fixes the locking means on the housing part.
