Building Block Wire Routing Structure for Protected Harness Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building block toys with wire harnesses are often cluttered, exposed, and prone to damage due to extrusion, leading to an incongruous and potentially broken wiring system.
Innovation Solution
The building block set incorporates a first block with a first wiring slot and a through-hole, allowing the wire harness to be routed inside or through the block, and includes a detachable wiring harness steering block that rotates to adjust the wire's direction, along with a block adapter block to manage the wire's path, forming channels and slots to minimize exposure and protect the harness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire harnesses are exposed on the building blocks, then electrical connection is achieved, but the appearance becomes cluttered and the wire harnesses are prone to damage
Solution Approach 1:
The wire harness is nested within hollow cavities of the building blocks. The first block contains a hollow cavity that accommodates the wire harness, and the second block's hollow cavity connects to the first block's cavity through a through-hole, creating a nested protection structure that hides the wire harness inside the blocks rather than exposing it externally.
Solution Approach 2:
A wire guide structure acts as an intermediary between the blocks to manage the wire harness. The wire guide includes a guide channel that directs the wire harness from the first block through the second block, and a guide hole that aligns with the through-hole to facilitate smooth wire passage while preventing extrusion damage.
2Device complexity
If wire harnesses are routed through blocks, then aesthetic appearance is improved, but the wire harness may be subject to extrusion and damage
Solution Approach 1:
The wire harness is nested within hollow cavities of the building blocks. The first block contains a hollow cavity that accommodates the wire harness, and the second block's hollow cavity connects to the first block's cavity through a through-hole, creating a nested protection structure that hides the wire harness inside the blocks rather than exposing it externally.
Solution Approach 2:
The hollow cavities and wire guide structure provide beforehand cushioning protection for the wire harness. The cavities create protective spaces that cushion the wire harness against extrusion forces, and the wire guide structure预先 (in advance) positions and protects the wire as it passes through the blocks, preventing damage before it can occur.
3Ease of manufacture
If wire harnesses are exposed and accessible, then ease of installation is improved, but the wire harnesses are more susceptible to damage and incongruous appearance
Solution Approach 1:
The hollow cavities and wire guide structures are pre-formed during block manufacturing. The wire harness installation path is prepared in advance through the through-holes and guide channels, allowing the wire to be easily routed through pre-prepared pathways rather than requiring complex post-assembly routing, thus maintaining ease of installation while ensuring protection.

AI summary
A building block assembly includes a first block formed with a first wiring slot located on an outer surface of the first block, the first wiring slot of the first block can cooperate with a second block to form a first harness channel for a wire harness to pass through and restricts a position of the wire harness. The first wiring harness channel is formed between the first block and the second block to limit the position of the wiring harness, which can avoid the wiring harness from being exposed to the outside world as far as possible and limit the routing of the wiring harness, so as to avoid confusion in the routing of the wiring harness.
