Solution Overview

Problem

Existing poles with externally attached devices are susceptible to environmental factors and lack effective user access control, leading to potential damage and tampering.

Innovation Solution

A pole unit with a device accommodation part that includes a first region accessible by a first user and a second region accessible by a second user, separated by partitions and cover members, allowing controlled access and protection of devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the device is externally attached to the coupling pole, then the device can be installed and accessed, but the device is easily affected by the external environment and lacks protection

Engineering Contradiction:

Improvedevice installationVSAvoidenvironmental exposure

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The device is nested within the coupling pole structure. The coupling pole includes a hollow interior space that accommodates the device, with the device positioned inside the pole rather than externally attached. This nesting provides environmental protection while maintaining accessibility through openings in the pole structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the device is externally attached to the coupling pole, then the device can be accessed by users, but the device lacks security and is susceptible to tampering

Engineering Contradiction:

Improvedevice accessibilityVSAvoiddevice security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The coupling pole is segmented into multiple access openings at different heights and positions. The first opening provides access to the device for general users, while the second opening (equipped with a lock) provides secure access for authorized personnel. This segmentation enables differentiated access control while maintaining device security.

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If the device is accommodated within the pole unit, then the device is protected from environmental factors, but the pole unit structure becomes more complex

Engineering Contradiction:

Improveenvironmental protectionVSAvoidpole unit structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The coupling pole serves multiple functions: it provides structural support, contains the device within its hollow interior, provides environmental protection, and offers multiple access openings for different user needs. By integrating these functions into a single multi-functional structure, the design achieves protection without excessive complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If multiple access openings are provided in the pole unit, then different users can access the device, but the pole structure becomes more complex

Engineering Contradiction:

Improveuser access controlVSAvoidpole structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Different regions of the coupling pole have different access characteristics. The first opening is designed for general access, while the second opening is equipped with locking mechanisms for secure access. This local differentiation of access quality enables versatile user control while maintaining overall structural simplicity.

Inventive Principle:

Principle #3Local quality
